I'm about to buy an Accessport for my '09. I have them for three STI's. I see that Cobb offers an adapter to allow many Subarus to get fuel pressure data and possibly more... from the CAN bus. However, a tuner told me that this utilization of a TGV connector doesn't work with my year of FXT. I'm in the process of dieting a newer WRX harness to put on the car. I'll have a built engine and will be using an Aeromotive FPR. Usually I just run a liquid-filled gauge on them, but I like the idea of being able to see it on my AP, or at least datalog some data or just use part of the wiring that's available for running a gauge cable. I'd like to do the same with an oil pressure sensor. I'm hoping the tuner can make changes so I can read these off the CAN. Part of this is I have an AIM EVO4S datalogger I can use while I am breaking in the car and doing an E-Tune with the AP (and gather additional data). I'd like to be able to record both if I can. Do you know about this or where I can go for help? www.cobbtuning.com/.../subaru-fuel-pressure...
I had apr fuel pump and shit was so poorly manufactured it completely shit the bed after the car got to operating temperatures causing the car to stall and die. Moved over to cobb tuning and hardware so no issues. This is really helpful
So I have an 04 STI with a new motor in it, cold air intake, down pipe, the works, I am currently running the stage 2 map and my DAM reading is consistently at .7 Is this something to be concerned about? There is no Fine Knock or feedback knock
Hey Blake, just got my AP .... you say you have a tuner, but i don't. any suggestions? and I'm new with this data logging. Watching your vids does help me understand what and where the numbers should be ... back again with, what should i do if i don't have a tuner ?
Thanks for the info bro. My 2015 sti had its check engine light came on which was a p0171 system too lean. I cleared it out on my accessport even though it said that it will reset the ecu as well. How did you do the p0171 code with its datalog after you cleared the code out even though it said reset the ecu on accessport?
Blake, you're awesome man, your videos help a lot. Keep up the good work man. I am tuning my car etune, and my tuner wants the pulls from 2k-5k, so do we hit the start and stop log from 2k and stop when it hit the 5k? can we hit stop after we shift it to 4th? thanks.
Am I wrong on this but wouldn't data logging from the actual vehicle on the road be more precise than putting it on a dyno? To me it feels like one is not the real world and the other is but if I'm not mistaken Dyno Tunes are known to be more accurate?
Great vid man. I've been watching your stuff since the E tune. We have a very similar setup. I'm still TP stage 1 with SF/box on a 2012 sedan. I never thought about reflashing now and then. Great idea. Eric at TP is the man. Anyway, I appreciate your vids and I hope you keep them coming! I'm curious how she runs after Eric fine tunes your map. Feedback knock always makes me cringe, probably for no reason as I rarely see over 1.4 at random times. Still tho. 👍🏻 this vid for running the exact same gauge layout.
Hii can plz make a video on af correction 1 and af learning 1 what number range they have to be in Are they have to be ona one side or opposite sides like if one in negative so other one have to be in postive
My car always get FBK when its hot out, I seen as bad as -2.80 to -4.20 (once), cant figure out if its pre det or drivetrain shock giving a ghost knock because I shift pretty fast to the next gear. I try to spray the I/C down roll a bit to let it evap the alcohol and water and give it a pull, seems to help out A LOT. I thought 3rd gear pulls were at 3k, i been doing them wrong lol. During the vid where was the knock occurring? I know starting at low revs it causes a lot of vibrations and registers knock or the engine just plain doesnt like it.
+Blake's Garage I've been seeing -1.40 for fine knock learning and feedback knock about once daily but its never during a pull. I might try re-flashing my ecu due to the big temp change since i initially installed it and see if it corrects it.
Thanks for the video Blake! Data logging is so important to know what's going on with your motor. Looks like you're peaking @ 19 psi of boost, which is about right for a stage 2 tune. BTW, your car is LOUD! I like it. What's your exhaust setup?
+Blake's Garage Interesting. I'm running a Cobb catted downpipe as well but my Q300 has a resonator. I wish Invidia made a non resonated midpipe that I could swap in. I may end up trying the Invidia N1 Race which is non resonated for more volume.
Max Speed Media Also I have 2 audio source for this video. One with an external mic by my exhaust. So that probably why it sounds so mean. It does sound good in person just not super loud.
I just put the Cobb accessport v3 and the Cobb sf intake and in my area I have 93 so I put stage 1+sf 93 and I was wondering if this tune is ok ? I am also going to put the nameless axel back exhaust with 4" mufflers do I need to change the tune ? I am very new to this any info you can give me most appreciated don't want to blow up my engine or anything. And after I put the full turbo back exhaust should I get it pro tuned, or do you think the accessport is safe and good enough? great channel I watch it all the time.
+LastHumansGarage Yeah I have never had an issue with it its always at 1.0 so I don't car to waste the space. I also data log my cruses a lot and check on the spreadsheet no issues with DAM.
Nartl Eric at Torqued Performance say's this is fine and knock is not to be worried about as long as it is not at WOT. Essentially, knock is inevitable from time to time and normal. I personally think feedback and fine knock should always remain at 0.00 regardless of eTune?
It can happen from getting on/off the gas too quick or rough shifts. I also got -2.8 and notice if I was smoother on the the throttle it didn't happen.
I got a 2016 wrx this year. In your opinion would you get an accessport or wait for the warranty to run out before you do any modifications that might get a claim denied. Thanks!
+Blake's Garage I'm kinda with you on getting one. I have a birthday coming up. I was going to go with the Cobb accessport with the sf intake. This is my first wrx. If I install these parts are they fairly safe in your opinion? And is an accessport enough to make the car run safe?
Blake's Garage yeah I was trying to figure that out I thought I might of had a boost leak because my accessport reads the same thing . I was worried because my homies reads at 0 psi on boost until he uses boost but it’s also a different car
I just bought u subaru wrx sti 2008 has invidia dowpipe, it was all good, I managed it a week, and now I got the check engine light, has the code po420, you think if I buy the access sports help me remove the check engine Light
Yony Loya if the car has a Downpipe it should already have an accessport and a tune. But yeah immediately take it to a Tuner and get a protune if you're running catless also I recommend to do a compression test. Make sure the engine is healthy.
Hey Blake, thanks for the great info... it helped answered a lot of questions. Would you by any chance know if need to re-tune my wrx if i'm swapping out for a catted down pipe? i'm going from catless to catted. I bought the car already like that... but Newbie question...on the accessport itself, is the stock map backed up on it? Thanks!
Hey dude another quick question for you. I'm really leaning towards the accessport. I noticed in the video you said your going to send in your data logs to a buddy to fine tune them. I don't know any one to do this personally. Is this something Cobb does? Also even though you have some knock is it causing any damage to your car while this is happening before you get it more fine tuned? Thanks again for your help!
+Blake Eaton I'm sending the logs to Eric at Torqued Performance you can check out his website he does E-Tune's. Eventually I will get Travis at Snail Performance to tune my car but I'm wanting to do the whole E85 Setup first. The knock I'm getting in this video is mostly due to my heat shield around my uppipe making rattling noises and a little during the shift after I reviewed the logs. A -1.4 can just be noise or false knock it's not a huge issue but it is something to keep an eye on if its repeatable. Cobb does not due fine tuning over the web as far as I know. When you first install the Cobb map keep an eye on these gauges you will probably notice some numbers coming up. Thats when you have to make the decision to get the car more dialed in. Or just wait until you have more mods and install them all at once so you don't have to go back in 6months and pay for another tune because you changed something.
+Blake's Garage First of all, very helpful videos! thanks a lot man ! .. I'm thinking of getting myself an AP, but also thinking of installing the Cobb SF intake and catback exhuast. Which should I go for first? Install all mods go for that logging(AP) and finish it off with the tune?? And if the mods come in first which AP would be best suitable? Any suggestions? Thank in advance! btw I have a 2011 subi wrx limited ...
Get the V3 Accesport first. DO NOT install the SF Intake without a Accessport tune. I would get the catback first then Accessport after that get the SF Intake.
Oh, that makes way more sense ! Thank you so much! Glad you actually have the time to respond to people! Love your vids! I'm learning a lot from 'em since I'm a beginner and all! Keep them coming! Subbed!
I've been told that monitoring feedback knock will make you go insane because of how much false knock these cars pick up! It's impossible to tune out all knock! It's an engine with explosions and its constantly dealing with different air temps, crappy gas, driver errors ect the knock sensor is there to protect the engine as well as fine knock learn! If your getting a -1.40 I wouldn't lose sleep over it!
+MaherMic Yeah -1.4 is normal. During pulls though it should be clean under WOT. I was getting some -2.8 and -4.20 randomly so that's why I was revising the tune. Also the latest revision is much better now. I have only gotten -1.4 feedback knock randomly under light throttle.
That's good! I need to get a Protune ASAP I don't throw any knock under load but when I am cruising in 5th I get a TON of Feedback knock. Case in point today I had a -11 feedback knock, again it only happens in 5th cruising with like 18-25% throttle. I cleaned the MAF and that didn't do anything gonna try and get it to a shop soon.
MaherMic Yeah that horrible. I would be scared to run that map too. Also thought you should downshift to 4th if you getting on the throttle in 5th. Most tuners will tell you to never go WOT in 5th unless your going like 130mph.
+MrDJC247 Yep it can be false knock from road noise. when you get higher numbers its something to be concerned about. If you can recreate the knock with your throttle inputs you most likely need to get your tune looked at.
Bro i have a question while driving normal i forgot to click data logging off while i'm driving the car will that be ok? Will it do any bad thing to my car engine or no?
Elisio Principe Well I recommend looking at a data log and you’ll know what I mean. Basically just a 20 second data log is a huge Excel file. And if you have no idea what the numbers mean then it’s basically useless garbage to you. Once you start understanding what all the information means then you can use it to your advantage but there’s no point and just did a login for a long period of time usually just during pull so maybe 10 seconds and then turn it off. Even that will be hard for a beginner to sort through.
Dude my fine knock learn has seen up to -4 and it's not even wot. Scaring me about meow a bit. It happens when I hit boost around 3500-4000 rpm. I noticed the more pressure I put on, the higher it returns in fine knock learn.
@@Flossydope yea. I had a cold air intake by mishi. Also had drop in filter by k&n. Both were causing heaps of false reading cause I didn't have a tgv delete. Went back to stock intake and all the false reading vanished. Runs smoother too.
Khang Xiong mmmmhhh, I have the Cobb sf intake installed and I’m running the ACN91 sf stage 1 map. I mean the car sounds normal nothing different just when I get on it I start getting negative reading from my feedback knock and my fine know learn. I get reading from -1.40 to 4.20 and depending on how much I accelerate it goes up to the -5’s so I don’t know what it could be I’m kinda scared lol.
@@Flossydope exactly. It's cause the tgv flapping causing false reading. If you get pro or etuned, you can ignore those false reading. Tho it's always gonna happen when you get on it even a little bit. And it causes your dam drop and lower multiplier. Which is a big reason I chose to go back. You could choose to do a that delete to help with that. Tho whatever happens next I dunno. Probably nothing if get a real tune. Not ots maps. It's just more money and not any significant gain for me as a daily driver. Yours is your choice tho.
+Blake's Garage Word Eric told me it wasn't a big deal as long as it wasn't under WOT so I was just curious if this normal cuz when you start seeing numbers when you cruising makes your heart jump a bit lol. Keep up the good work homie
I’ve been having a/f problems only when cruising, my a/f learning 1 is giving me +8/-8 numbers only when normal cruising. Idling and WOT is perfectly fine a/f at 14.7 and around 11-10 for wot.
What are your mods Blake? Sounds beastly. I had some feedback knock last night and it reached - 6.30 just crusing, is that a bad number? I don't know whether I have a problem or not? Maybe you can help me, I have a Cobb V3 ap and a 04 wrx with a lot of mods. This whole knock thing is new to me and data logging. Please let me know. Thank you, Eric Miller
+eric miller hey Eric. Ever so often you can get false knock. Just make sure it's not happening under load and you can't replicate it with throttle inputs. You may want to ref lash the map sometimes that can help.
I am stock 100% with HD heat shields and blankets. Including air filter oem. Car ran like poo w high flow air filter -10 miles only. Has 26000 miles. Oil changes 3000-4000 miles all at dealership. (Free- lifetime Gold member 2 free oil changes a year (they dont care if more- 100k warranty)
Ulises Jaquez yeah that's not good you're gonna want to get your tooth looked at what tune are you running? If you're having issues like that I would probably take it to a protuner and get them to figure it out. Basically her car is seeing Doc and pulling timing I would most likely replace the spark plugs first if you haven't in a long time just because that can cause issues and that's an easy repair. I have a video on how to do that if you look it up.
ok thanks man that really help me alot! i havent change the spark plugs in like 7 months, but i will take it to a protuner, im just running the stock cobb tunes
Ulises Jaquez yeah if you're running the stock OTS map I would definitely take it easy on that sounds like you're having issues and I wouldn't want that to become a problem. You may have to take it to a shop where they can diagnose the issues.
why do you bother with the intake temp? the air passes thru your intercooler before it combusts. the charge temp!! and it must be hot as shit down in Mexico!!

www.cobbtuning.com/.../subaru-fuel-pressure...
awesome video. the liver night i did a third gear pull on it showed the -1.4. now I feel better having watched your video.
I had apr fuel pump and shit was so poorly manufactured it completely shit the bed after the car got to operating temperatures causing the car to stall and die. Moved over to cobb tuning and hardware so no issues. This is really helpful
great explanation sir!! Im sure this will help alot of audience.
Jw, are you bilingual?
Everyone needs there own 'Lil Mexico, there home away from home LOL. Good vid man! Hope everything gets worked out. Keep us updated!
Thanks for the vid! Helped a lot. Just got my base map for my custom tune.
Logging as we speak.
Cool channel man, met you out at sac raceway, silver 02 bugeye, thanks for all the information and help. I'll be peepin your videos, keep em comin!!
+Robert Molina Hey what's up Robert, no problem man. It was cool to see you shave 1 second off your first pass.
haha, too perfect Blake. I gotta send Eric a couple pulls I did last weekend too.
Excellent video man. Very informative. Thanks for posting it.
So I have an 04 STI with a new motor in it, cold air intake, down pipe, the works, I am currently running the stage 2 map and my DAM reading is consistently at .7
Is this something to be concerned about? There is no Fine Knock or feedback knock
Great video! Well explained and right on point. Thanks
Dude fantastic video explanation on this!! Great info, will have to refer back to this someday I have an AP!! :p Have a great weekend man!!!
great video, i got an etune from a place in upstate NY called Turbotek tunning. i will be doing this tonight!
+65PontiacTempest Nice! Make sure to check out my Exporting datalogs video if you haven't already.
+Blake's Garage thanks, i watched it after i already sent the logs back. it was pretty simple though.
Thanks man im in the proccess of logging as of right now
Hey Blake, just got my AP .... you say you have a tuner, but i don't. any suggestions? and I'm new with this data logging. Watching your vids does help me understand what and where the numbers should be ... back again with, what should i do if i don't have a tuner ?
Thanks for the info bro. My 2015 sti had its check engine light came on which was a p0171 system too lean. I cleared it out on my accessport even though it said that it will reset the ecu as well. How did you do the p0171 code with its datalog after you cleared the code out even though it said reset the ecu on accessport?
Thanks your doing a lot of help
Will the accessport save multiple data logs? Or each time it logs, it overwrites the last one?
Yeah it can save multiple data logs..
You need to get a cold air intake! My intake temps are usually only a few degrees off from the outside temp.
David Mudrik You could also have a better inner cooler 🤷🏻♀️
Gota love those 3rd gear pulls in Mexico 😀
+WRX508 Always!
In Mexico la vida Es más sabrosa bro!
Due you have a upgraded intercooler? Seems like it would be a nice upgrade.
+Andrew Thomson Nope, not yet when funds allow it will happen.
Very informational video nicely done! When are you gonna post the quarter mile video?
+David Mudrik Probably Monday.
Can you delete your old data log? If you can....how do you do it? Thanks. By the way. great video.
Blake, you're awesome man, your videos help a lot. Keep up the good work man. I am tuning my car etune, and my tuner wants the pulls from 2k-5k, so do we hit the start and stop log from 2k and stop when it hit the 5k? can we hit stop after we shift it to 4th? thanks.
Trung Ho you can start stop before and after you can tell what's going on in a log no problem.
I don’t have the intake box and my intake temps never get 20 degrees above ambient temps, not sure why the cold air box is makin it warmer
Am I wrong on this but wouldn't data logging from the actual vehicle on the road be more precise than putting it on a dyno? To me it feels like one is not the real world and the other is but if I'm not mistaken Dyno Tunes are known to be more accurate?

+Adam Fiekens Thanks Adam! yeah i don't like seeing anything but -1.4 is not that scary. Eric does a great job at fixing stuff up.
Can I use stage 2 aggressive map with 92 octane gas here in seattle?
Hii can plz make a video on af correction 1 and af learning 1 what number range they have to be in
Are they have to be ona one side or opposite sides like if one in negative so other one have to be in postive

Thank you so much bruh you have been very helpful. Thank you.
+Blake's Garage
I've been seeing -1.40 for fine knock learning and feedback knock about once daily but its never during a pull. I might try re-flashing my ecu due to the big temp change since i initially installed it and see if it corrects it.
+Griffin Hall a lot of time that helps for a bit. -1.4 is pretty common. If it reads anything higher you may want to get the tune cleaned up.
What exactly do you mean by re-flashing the ECU? Just putting the map back on to reset it?
Thanks for the video Blake! Data logging is so important to know what's going on with your motor. Looks like you're peaking @ 19 psi of boost, which is about right for a stage 2 tune. BTW, your car is LOUD! I like it. What's your exhaust setup?
+Max Speed Media Cobb DP Catted and SPT Catback the midpipe is SPT and its non resonated.
+Blake's Garage Interesting. I'm running a Cobb catted downpipe as well but my Q300 has a resonator. I wish Invidia made a non resonated midpipe that I could swap in. I may end up trying the Invidia N1 Race which is non resonated for more volume.

What exhaust system and header/manifold do you have? Sounds really good!
SPT and Cobb downpipe stock headers
wow bro you're awesome, teaching me alot
I just put the Cobb accessport v3 and the Cobb sf intake and in my area I have 93 so I put stage 1+sf 93 and I was wondering if this tune is ok ? I am also going to put the nameless axel back exhaust with 4" mufflers do I need to change the tune ? I am very new to this any info you can give me most appreciated don't want to blow up my engine or anything. And after I put the full turbo back exhaust should I get it pro tuned, or do you think the accessport is safe and good enough? great channel I watch it all the time.
123valve I would always recommend a pro tune wouldn't run the OTS tune for very long.
+Blake's Garage why is that? Cobb stage 1 ots map goes mostly off the stock tune. Stage 1 is basically stock.
my feedback knock went to -9.80 and sometimes goes -7.00. ive been getting knocks lately. what should I do? I don't have a tuner.
Sell the car. Go back to stock tune.
first thing i notice is DAM isn't one of your 6 gauge choices. still watching.. I like the idea of monitoring intake temps tho..
damn ur car sounds mean.
+LastHumansGarage Yeah I have never had an issue with it its always at 1.0 so I don't car to waste the space. I also data log my cruses a lot and check on the spreadsheet no issues with DAM.
+LastHumansGarage Thanks!
Would this be usefull on a wrx 2013 stock ?
good video. helped out a lot.
I know this is an old video but is that a center console riser?
so you just click data log before 3rd gear pull or while cruising?
I need an etune but I’m genuinely not experienced on how to drive this car fast...
My 2017 STI on the stage 1 map will read a 1.4 or 2.80 feedback knock. Should I worry about it?
Nartl Eric at Torqued Performance say's this is fine and knock is not to be worried about as long as it is not at WOT. Essentially, knock is inevitable from time to time and normal. I personally think feedback and fine knock should always remain at 0.00 regardless of eTune?
It can happen from getting on/off the gas too quick or rough shifts. I also got -2.8 and notice if I was smoother on the the throttle it didn't happen.
thanks very informative
+Cooper Connell No problem glad I could help.
now you should do a video on how to find the tune on the ap software and email it?
+Ricky Archundia I can if you want, do you really want to see that?
Yeah that be awesome thats the part i was struggling with when i was tuning my fiesta ST
Ricky Archundia Ok cool, I can do a video on that soon.
My af learning 1 is always at 10-11 is that bad.?
Hey so I’m on a stage on with sf intake but I can’t seem to get more then 13 psi of boost but I see your up in the 18 psi why would that be ?
Hey just found the channel subbed.
+Moto WINGOO Cool Thanks man!
I got a 2016 wrx this year. In your opinion would you get an accessport or wait for the warranty to run out before you do any modifications that might get a claim denied. Thanks!
+Blake Eaton If it were me I would get one. But thats the hard decision everyone has to make. Power or Warranty.
+Blake's Garage I'm kinda with you on getting one. I have a birthday coming up. I was going to go with the Cobb accessport with the sf intake. This is my first wrx. If I install these parts are they fairly safe in your opinion? And is an accessport enough to make the car run safe?
How do you upload and send the data log to a tuner
PC cobb ap
I get some feedback knock randomly and it’s concerning idk why like -1.40 randomly
what sort of engine is that to have no vacuum on idle should be -18 to -23
those applicable into 335i also?
So I’m trying to figure out why your boost is at negative reading ?
Why would that be
Vacuum at idle, boost when boost is built in the manifold.
Blake's Garage yeah I was trying to figure that out I thought I might of had a boost leak because my accessport reads the same thing . I was worried because my homies reads at 0 psi on boost until he uses boost but it’s also a different car
I just bought u subaru wrx sti 2008 has invidia dowpipe, it was all good, I managed it a week, and now I got the check engine light, has the code po420, you think if I buy the access sports help me remove the check engine Light
Yony Loya if the car has a Downpipe it should already have an accessport and a tune. But yeah immediately take it to a Tuner and get a protune if you're running catless also I recommend to do a compression test. Make sure the engine is healthy.

Hey Blake, thanks for the great info... it helped answered a lot of questions. Would you by any chance know if need to re-tune my wrx if i'm swapping out for a catted down pipe? i'm going from catless to catted. I bought the car already like that... but Newbie question...on the accessport itself, is the stock map backed up on it? Thanks!
Phuong On yes you will definitely need a tune.
I'm unsure if Eric is a Cobb tunner or your personal tunner?
Jose Camacho cobb tuner, go to torqued performance.com but he does strictly subarus
Hey dude another quick question for you. I'm really leaning towards the accessport. I noticed in the video you said your going to send in your data logs to a buddy to fine tune them. I don't know any one to do this personally. Is this something Cobb does? Also even though you have some knock is it causing any damage to your car while this is happening before you get it more fine tuned? Thanks again for your help!
+Blake Eaton I'm sending the logs to Eric at Torqued Performance you can check out his website he does E-Tune's. Eventually I will get Travis at Snail Performance to tune my car but I'm wanting to do the whole E85 Setup first. The knock I'm getting in this video is mostly due to my heat shield around my uppipe making rattling noises and a little during the shift after I reviewed the logs. A -1.4 can just be noise or false knock it's not a huge issue but it is something to keep an eye on if its repeatable. Cobb does not due fine tuning over the web as far as I know. When you first install the Cobb map keep an eye on these gauges you will probably notice some numbers coming up. Thats when you have to make the decision to get the car more dialed in. Or just wait until you have more mods and install them all at once so you don't have to go back in 6months and pay for another tune because you changed something.
+Blake's Garage ok very good! Thanks so much for all the great info! I really appreciate it!

Get the V3 Accesport first. DO NOT install the SF Intake without a Accessport tune. I would get the catback first then Accessport after that get the SF Intake.
Oh, that makes way more sense ! Thank you so much! Glad you actually have the time to respond to people! Love your vids! I'm learning a lot from 'em since I'm a beginner and all! Keep them coming! Subbed!
Hey Blake I have a question when I'm driving my wrx which is stage 1 I get -1.4 knock feedback should be worried ?
+harrisbest1 no that is normal. Just make sure you can't keep repeating the knock with throttle input.
Will this work for a 2016 Subaru Impreza hatchback 2.0
nope
I think someone may already mentioned it but you should do a video on how to pull the log from the ap to what it looks like on the spreadsheet
+Dustin Fox Thanks for the feedback. I'm surprised how many people want to see this. I will definitely make a video on it.
I've been told that monitoring feedback knock will make you go insane because of how much false knock these cars pick up! It's impossible to tune out all knock! It's an engine with explosions and its constantly dealing with different air temps, crappy gas, driver errors ect the knock sensor is there to protect the engine as well as fine knock learn! If your getting a -1.40 I wouldn't lose sleep over it!
+MaherMic Yeah -1.4 is normal. During pulls though it should be clean under WOT. I was getting some -2.8 and -4.20 randomly so that's why I was revising the tune. Also the latest revision is much better now. I have only gotten -1.4 feedback knock randomly under light throttle.
That's good! I need to get a Protune ASAP I don't throw any knock under load but when I am cruising in 5th I get a TON of Feedback knock. Case in point today I had a -11 feedback knock, again it only happens in 5th cruising with like 18-25% throttle. I cleaned the MAF and that didn't do anything gonna try and get it to a shop soon.
And that's just on a Stage 1 91 octane Cobb OTS Map
MaherMic Yeah that horrible. I would be scared to run that map too. Also thought you should downshift to 4th if you getting on the throttle in 5th. Most tuners will tell you to never go WOT in 5th unless your going like 130mph.
Yes sir :) I have never or will never go WOT in 5th!
I always seem to get about -1.40 feedback knock..
But apparently it can be set off by any noise similar to the sound of actual knock. Is that true?
+MrDJC247 yea 1.4 is okay. The higher the number the worse it is (obviously).
+MrDJC247 Yep it can be false knock from road noise. when you get higher numbers its something to be concerned about. If you can recreate the knock with your throttle inputs you most likely need to get your tune looked at.
+Blake's Garage exactly. repeatable means you need to reach out to your tuner asap.
+Blake's Garage Isn't it bad to put all that load on your engine by going WOT at 2500 rpm?
+Bryce not it you are in the correct gear. Don't do it in 4th or 5th
Bro i have a question while driving normal i forgot to click data logging off while i'm driving the car will that be ok? Will it do any bad thing to my car engine or no?
Nothing will happen to the engine. Just a giant log to go through.
@@BlakesGarage ok thanks. Does giant log a bad thing or not at all?
Elisio Principe Well I recommend looking at a data log and you’ll know what I mean. Basically just a 20 second data log is a huge Excel file. And if you have no idea what the numbers mean then it’s basically useless garbage to you. Once you start understanding what all the information means then you can use it to your advantage but there’s no point and just did a login for a long period of time usually just during pull so maybe 10 seconds and then turn it off. Even that will be hard for a beginner to sort through.
Dude my fine knock learn has seen up to -4 and it's not even wot. Scaring me about meow a bit. It happens when I hit boost around 3500-4000 rpm. I noticed the more pressure I put on, the higher it returns in fine knock learn.
Khang Xiong Same, did you ever find out why?
@@Flossydope yea. I had a cold air intake by mishi. Also had drop in filter by k&n. Both were causing heaps of false reading cause I didn't have a tgv delete. Went back to stock intake and all the false reading vanished. Runs smoother too.
Khang Xiong mmmmhhh, I have the Cobb sf intake installed and I’m running the ACN91 sf stage 1 map. I mean the car sounds normal nothing different just when I get on it I start getting negative reading from my feedback knock and my fine know learn. I get reading from -1.40 to 4.20 and depending on how much I accelerate it goes up to the -5’s so I don’t know what it could be I’m kinda scared lol.
@@Flossydope exactly. It's cause the tgv flapping causing false reading. If you get pro or etuned, you can ignore those false reading. Tho it's always gonna happen when you get on it even a little bit. And it causes your dam drop and lower multiplier. Which is a big reason I chose to go back. You could choose to do a that delete to help with that. Tho whatever happens next I dunno. Probably nothing if get a real tune. Not ots maps. It's just more money and not any significant gain for me as a daily driver. Yours is your choice tho.
Khang Xiong So your basically saying it’s just giving me false readings and I don’t have too much to worry about.
Hey do you get random feed back knocks when cruising in 4th?
+jon cash usually more so in 5th. Only under light throttle. It's getting worked out right now and its way better with the revised maps.
+Blake's Garage Word Eric told me it wasn't a big deal as long as it wasn't under WOT so I was just curious if this normal cuz when you start seeing numbers when you cruising makes your heart jump a bit lol. Keep up the good work homie
jon cash Yeah, WOT is the scary one. I was getting some kick but it may be the uppipe making some noise form the heat shield.
Starting a pull at 2.5k with wot? Seems a little low...
Drew H every Dyno tuner starts pulls at 2.5K on Subarus.
3-4k
I’ve been having a/f problems only when cruising, my a/f learning 1 is giving me +8/-8 numbers only when normal cruising. Idling and WOT is perfectly fine a/f at 14.7 and around 11-10 for wot.
I sure love those mexican's roads lol
Cobb mentions FB K and FB K Learn of 1.40-1.41 / -1.40-1.41 is not abnormal.
What are your mods Blake? Sounds beastly. I had some feedback knock last night and it reached - 6.30 just crusing, is that a bad number? I don't know whether I have a problem or not? Maybe you can help me, I have a Cobb V3 ap and a 04 wrx with a lot of mods. This whole knock thing is new to me and data logging. Please let me know.
Thank you,
Eric Miller
+eric miller hey Eric. Ever so often you can get false knock. Just make sure it's not happening under load and you can't replicate it with throttle inputs. You may want to ref lash the map sometimes that can help.
Awesome... Thanks for the great info. Keep the sweet videos coming.. Btw what's your mod list?
What speed do I start at and what speed do I end at for third gear tune thanks
Ha! I'm always forgetting to hit the data-logging botton too. Frustrating!
is it me or hes double shifting instead of skipping gears?
Not to be rude or anything but you mistyped Accessport in the video title
+Andreas Scherrer HAHAH Oh yeah thanks! Fixed.
My 14Wrx has -20 psi vacuum warm at idle
Toby Head you may have a vacuum leak. That's the af learn?
Blake's Garage
If i had a vacuum leak- it would pull less vacuum not more.
You have a leak, or worn rings, or low compression.
Also
My vacuum has been identical for every start up since new.
I am stock 100% with HD heat shields and blankets. Including air filter oem.
Car ran like poo w high flow air filter -10 miles only. Has 26000 miles. Oil changes 3000-4000 miles all at dealership. (Free- lifetime Gold member 2 free oil changes a year (they dont care if more- 100k warranty)
The stock intercooler to Throttle body hose like to leak. I can literally make a boost leak on the stock hose after one autox run.
Where'd the top of your forehead go? Lol
+Cali_WRX It fell off!
deadliest facial
Monitoring intake temps is useless
Is the low DAM dangerous?
Ulises Jaquez DAM should stay constant. For my ECU it should be 1.0 if this changes you have issues. Get it figured out before you start doing pulls.
oh ok, yea im getting 1.0 and then sometimes drop to .652 on stage 2, on stage one it change from 1.0 to .750
Ulises Jaquez yeah that's not good you're gonna want to get your tooth looked at what tune are you running? If you're having issues like that I would probably take it to a protuner and get them to figure it out. Basically her car is seeing Doc and pulling timing I would most likely replace the spark plugs first if you haven't in a long time just because that can cause issues and that's an easy repair. I have a video on how to do that if you look it up.
ok thanks man that really help me alot! i havent change the spark plugs in like 7 months, but i will take it to a protuner, im just running the stock cobb tunes
Ulises Jaquez yeah if you're running the stock OTS map I would definitely take it easy on that sounds like you're having issues and I wouldn't want that to become a problem. You may have to take it to a shop where they can diagnose the issues.
Your hands seem very shakey
Isaac Miller wheels and tires need balancing...
why do you bother with the intake temp? the air passes thru your intercooler before it combusts. the charge temp!! and it must be hot as shit down in Mexico!!
Hey just found the channel subbed.
