V9 IS FANTASTIC !!! MY CAR LOVES IT !!! No placebo affect. and with my straight pipes with catless downpipes holy EFF!!! the burble is loud always on shift change and letting off the gas and the huge pop when down shifting and love it
Needed 5 comments..straight pipe it mate.😀 I just installed version 9. 1+. Its night and day on my 09 335i xdrive. Very smooth acceleration accross all gears. Version 8.1..I was not getting boost until 3 gear or 4.5k rpm. Iam still hesitant to floor it until I get CP installed. Only have FMIC and DCI so far. Keep up the great videos. Cheers.
Haha thanks for the comment..... I guess the exhaust is going to get cut up now. Haha We were really happy with how the v9 played out. Looking forward to getting a cooler on this car and drive stage 1 plus!
It definitely gets addicting and pretty amazing how mhd2 + litterally transformed my car. I started with a cat back and now have a fmic,dci,inlets,charge pipe and dps. Just make sure you handle all maintenance first! These cars are definitely one of the best bang for your bucks out there imo. Once I get sick of the n54 I will upgrade to the big brother s55, basically the n54 on steroids. The cooling is phenomenal. Also, if you don't have an oil cooler on ur n54 you will still heat soak after pushing it and it doesn't take much.. Easy way to tell is by turning your wheel all the way to the left and looking to see if you have a vent in your wheel well. I thought all 08+ came equipped but apparently it was sport models only which is a bougs move on BMW because these mfers are ovens,lol. Edit: when I mention heak soat I've personally never ran into an issue because I know my car and when to give it a break. I don't let it go past 250F and on 90-100 degree days that doesn't take much. But in the cold weather it is a different animal..
@@6mtcruiser truthfully, I’d recommend staying updated on the map versions unless you have a custom tune with a specific map. I haven’t really paid too close of attention to give a brief description of the difference besides at that time I noticed a much smoother ideal and throttle response.
Version changes in MHD are not really about more power but mostly more driveability and smoothness... You should make videos about the different stages and their mods, comparing Vbox times and monitoring. :D
You think leave the resonator? The miltek on my black car, is so quiet there are quite a few people online talking about how quiet they are. I think we need one more comment and i'll start cutting parts out and see how it goes haha.
@@ZeroTo60Tube The E92 has no resonator, only secondary cats... The E90 does have a resonator. The best sounding exhaust IMO is catless downpipes and rest of the exhaust stock with muffler valve permanently open. Try it :D If you want it loud then as suggested above, full straight pipe with an aftermarket resonator to kill the rasp. :D
@@JerainJezza To be honest i havent had a good look under this 335 with the modified stock exhaust. My black one with the miltek does have resonators. No cats, but my is so quiet i assumed they all had resonators. This might explain why mine sounds so close to stock.
Zero To 60 I have an e90 single turbo so it’s a catless dp. Resonators are still on but with a muffler delete. It’s loud enough but not too loud. Sounds great
@@ZeroTo60Tube I have a 135i with a custom single 3.5" straight pipe from the downpipes with quad tail pipes, it just has a Vibrant Performance resonator in the middle to avoid rasp. It sounds amazing, intoxicating. You can search for BMR exhaust on 135i, it is the same setup that I have.
Well V9 will be installed tomorrow that's for sure. One thing I was wondering was if you were thinking of installing an XHP tune on the trans? I am hearing that removing the torque limitations that the TCU manages gives even more mid range grunt. Also MHD has a flash option that takes into account an XHP trans tune, perhaps a new avenue to explore and if you had the resources a dyno day would be great. As usual great work and keep em coming.
Just open up the left muffler and wrap the perforated pipe then wire the exhaust flap on a switch .you can have cat back straight pipe but have it switchable not that it gets that loud . The secondary cats and standard turbo really dull the sound.
Sincerely appreciate all the testing and knowledge you guys bring to this channel! I have been running stock map (MHD) for around two weeks, no issues/noises/shudders/faults/etc. Two days ago I changed to stage 1 MHD (Have previously used before and every time noticed the following) and have noticed an intermittent shuddering (Vague but noticeable) when idling more so in Drive but still in Park, a lurching sensation when applying throttle again after slowing down (not complete stop), as well as a non-linear acceleration (At just under 3K RPM it feels as though full boost suddenly kicks in if I am anywhere from mid to full throttle). Is this a sign the turbos or even one of the fuel pumps are nearing failure? (All the above are fixed when re-mapped to stock map).
There are a few things that could be going on that spring to mind. Firstly the MHD tune is probably trying to get the car up on boost sooner, it may be requesting x amount of wgdc to hit x amount of boost at a certain rpm and load, then over cooking it. Assuming the hardware is all as it should be, this will eventually relearn and sort itself out over time and become smoother. Using MHD wastegate rattle fix can cause a similar effect. Have you tried linear throttle mapping option in MHD. I believe even the OTS tunes for MHD manipulate pedal input to give the “effect” of more power. So you may be inputting 10% throttle but the tune is opening the throttle body by 50% etc. This is how the pedal tuners work which a lot of people seem to rave about. It’s basically tricking our brains into thinking the car has more power. As for the judder at idle. I can’t think of anything that would directly cause this within the tune. It may be O2 sensor adaptations, or even coils/plugs on their way out. Have you gone through the typical maintenance steps for the N54s yet? Tuning a N54 is very different to the older EFI systems. No longer do the tuners program x amount of timing advance and x amount of fuel for a said rpm range. Its a matter of manipulating so many tables like load, fuel, timing, boost and many more etc that all bounce of each other to get a desired result. So generally they are not that different from a stock map in the way the cars behave themselves.
@@ZeroTo60Tube Thanks for the feedback. Understandably it's hard to tell what's going on without reading logs (might be worth me investing in this). But, I have already chosen for linear throttle mapping and have not enabled wastegate rattle fix. I gave her a fresh new set of plugs about 11 months ago after going to MHD v7 Stage 1 and getting consistent misfires. After changing the plugs I didnt have any issues, including this sudden increase in boost. I had gone back to stock map for around 5 months purely for daily driving and theoretically better efficiency. Only now on V8 and V9 Beta have I had these new issues (also the same when tested on V7). Also, should there be a sensation of increased vibrations when under full load on these higher maps? I've noticed this when on full load, I can only describe it has an engine that doesnt feel like it is running quite as smooth as it should be under full load. How long would you typically expect for the map to "learn"?
I’ve code via MHD scan with 3100 and 2abc in active, 2fda and 2fdb in shadow. Due to these codes, changed boost solenoids, CP sensor and crank sensor. Any advise?
Do not straight pipe it. Mine was essentially a straight pipe and still had vibrant resonators in the middle. Bought a whole new OEM exhaust and just run downipes with oem secondary cats and flapper stays open. All the sound I need
Ohhhh interesting.... I think i might be on your page. But we got 5 comments, sooooooo i will at least try the straight pipe idea. I think i will get a bolt in rear section made, so i can go back to my current setup with out too much hassle. Just to be safe.... we'll see what it sounds like.
Hi Guys, Newbie with e92 N54 DCT 335i and just acquired MHD app and monitoring. Have done all maintenance, new solenoids, delphi coils, bosch plugs, serviced injectors incl decouplers and seals. MHD V8 stage 1 98 ron throws up wide variations in timing corrections, fine with 95 ron. Using BP 98 plus 6 lts e85 to a full tank. Installed MHD v9 stage 1 95 ron today and runs really smooth and feels quicker. no timing corrections. However after finishing logs on the way home in manual sports mode gunning it, an engine warning light came up and car ran like a chaff cutter! Checked codes and it was a misfire in cylinder 6.

Or process of elimination by substituting coils or injectors? Any advice appreciated, tkx.
Hi Gerard, thanks for the message. Assuming its a spark misfire. First port of call for me would be the plugs. I'd be tempted to try the NGK 1 step colder. Gapped down to .22, they will help reduce the chance of misfires over the bosch plugs. Other than that have you checked the condition of the battery lately? Even if they start the car fine, they can cause spark missfire if they are not maintaining proper voltage when under load. Also what country are you based in?
@@ZeroTo60Tube In Australia too. Will try swapping coils, plugs first, then injector. Yes battery is a bit weak so could be fuel pump not getting enough power under load. Will let u know how I go. Tkx for advice.
Hi Guys got it sorted faulty injector on cylinder 6. Swapped it into 5 and misfires there. Installed mate's spare index 6 (3) rear bank and no misfires or faults. Will run some logs this week. FMIC and stage 1+ next few months.
Hi Richard, Thanks for the comment. Yes we are, the AC turns off at a certain rpm anyway, it doesn't seem to affect the times at all whether it's on or off. We have tried every single way possible to get best time out of this car. Including low rpm shifts, starting in second you name it. The biggest thing that makes a difference is how you get it off the line. It's a very fine line between getting traction and accelerating vs too much wheel spin. The vbox has been so good for seeing what actually works.
I've done a couple of DIY fuel pump upgrades with the walbro 460s and modifying the mount in the stock bucket, in all honesty if i had the money for a decent one like the race-works stage 2, i would jump on it. If you have any other questions let us know. Done quite a few mods to a few N54s now.
Hey guys I have done version 9 yesterday and my car started to hesitate a little in high gears it may be that my car is adapting to the tune ? How long was yours not performing perfectly? I’m thinking about going to version 8
Hey Lilsims, I think read last week that it can take up to 100miles for a car to fully "adapt", however you should see pretty close to normal behaviour with in an hour of driving. There were a few people that commented on the first vid we put up about version 9 who said it took 3 days for their cars to settle down. So let us know how you go. Drive sensibly in the mean time and if you are doing any wot runs, try and log them so you can check everything is running safely. As we mention in this video, if your car doesn't sort itself out, it will be a warning sign that something hardware related is on the way out.
@@ZeroTo60Tube Hey, I tried V9 yesterday but felt a bit jerky compared to V10 which I have been using, had tried V9 cause I ready somewhere that you won't get throttle closures, which I have been getting with V10 albeit it is imperceptable..what parameteres would you say the cars "learn" or "adapt" to? timing? wastegate duty cycle? etc?
@@dextershumba7262 The DME adapts to everything. Every sensor is used in its calculations and reflect what it does. It has targets to meet from the calculation and it will escentially adjust sensor data minimally to meet those targets. Thats what the adaption is. Throttle closures are not the end of the world, assuming you have an accurate boost reading. The tune is made for cars up high in Colorado and at sea level. The same car with the same tune in those 2 locations will make a big difference in boost levels with the same targets with the tune. If the sea level car exceeds the boost limit it will close throttle. Also if you remove a restriction in the inlets, it will do the same. The turbos make boost easier and over shoot boost target. If your hardware is spot on run the latest maps. they will work better. V10 is the most complex map and will be smarter with how it makes power. However hardware has to be in good condition. If v9 is better, you have a hardware issue that V9 can't see with is more basic tuning.
@@ZeroTo60Tube sincere apologies for not having seen this till now alas. I am always going through your channel and referencing videos and comments for the sake of learning and understanding the platform better. Apprecite the shring of knowledge, it really makes sense and ill keep tht in mind. Jut got BMS intercooler so going to be messing around with some maps and see what the car likes best. I'm still blown away by Christians 10sec 17t e40 run. I have some "questions/thoughts" ref ots maps nd upgraded turbos.
Dylan is getting very annoyed that we keep buying other cars..... he has downpipes, LPFP and a few other bits we are due to fit and get it up to stage 2 plus. Will be on the channel very soon.
Richard Hill, you should definitely be running a MHD back end flash with the JB4 at least. The JB4s are brilliant if you are a self tinkerer. But if you aren't playing with the extra features of the JB4, you might not need it. The JB4 is a brilliant tool, but it is probably overkill for 80% of the N54 cars out there. I'm keeping mine, but i want to go big with power. If you have things mods port injection, the JB4 makes a lot of sense.
Ken who writes the MHD n54 maps is now a zeroto60 member and he has been telling our group about how good these V10 is. Not only the tuning side but the way MHD in the back end works has some big improvements. 100% get on v10. If the car is in good mechanically condition and stock turbos it will be the best it and smoothest its ever run.
This one is stock, we will be doing a transmission service, with the bridge seal replacement soon. Once that is done we will get on to XHP. Well thats the plan anyway.
Guys those times are not right . I’ve done exhaust Down pipes, jb4 tune , air filters 5”stepped Intercooler and Nanking AR1 and on 8psi got 5.1 and on 12 psi 4.5 , on the e85 tune at around 17-18psi I clock below 4seconds every time best at 3.7sec I’d be looking for what’s wrong cause those times are way high,FYI all my runs are with traction off altogether,I’m. not trolling u guys just trying to help but I’d be checking for a boost leak , plugs and anything on the cold side,
They are amazing times man, assuming you are talking about street times not on a prepped surface, the only people i see getting those times on the street are using a very optimistic timing device (meaning they are wrong) or all wheel drive. Have you ever used a dragy or a vbox to get an accurate time? Let me know your dragy username if you have one would love to check the verified times out.
This car, with 2 people in it, on this particular road was around 6.6. The factory claimed times are very hard to get in real world scenario. We’ve done around a 1000 timed runs now and not much gets close to claimed times. And even when you add power it then becomes a battle for traction on a crap surface.
Some cars we’ve tested it makes a difference but the 335s are already on the edge of spinning the tyres and losing traction so it didn’t really make a difference in 0-100 time. Maybe top speed would? But it definitely doesn’t take half a second off the 0-100 time... unfortunately. If it did I would never run AC 😂
@@Richard-ck5zk Out of curiosity, have you ever actually measured the performance difference back to back with something accurate. I fear placebo may be having an impact here on what you are feeling. Dont get me wrong on a car with 100hp yes, a/c is a noticeable. But on something with getting on close to 400hp the 3--5 hp the compressor draws would be mighty hard to pick up on. Also like i mentioned on your other post nearly all modern cars cut the ac compressor off past a certain rpm point.
I can't comment for road course, but think you'll be fine. The most important thing is get it on the car and do some logs before the event. You dont really want to be running an untested setup on race day. Do the prep and make sure the day goes smooth.
@@ZeroTo60Tube Yes that's what I'm doing now, logs look fine but I will go on a 30 minute backroad drive and log again just in case. Also, have the rfp v13 maps but they might be too aggressive and create too much engine oil heat. If nothing works I'll run stock map or stage 1 until I get a custom map. Thank you for your feedback!
@@in54ne82 Fingers crossed for you dude. Sounds like you have it under control. Honestly both v9 and rfp should be safe. Its really just a matter of keeping an eye on any hardware faults that may be arising.
@@ZeroTo60Tube My previous track days had no issues on stage 1 rfp boost by gear maps at around 70F degree weather, 20 minute sessions. This time I'm commuting 2.5 hours away then beat on the car at a 90F to 100F degree weather maybe more then I'll have to drive back. That's why I was mainly asking lol I'm a little nervous not gonna lie. For sure I'll keep an eye on my logs.
@@xXPred4torXx Out of curiosity how did you measure your performance difference? You can see in the vid, i think it's going to be quicker on 9 but i was really sure. I've done around 400 0-100kmh in the last few years so my but dyno is little more sensitive than most and version 9 still took me by surprise.
@@tuiwilson5486 It will definitely be fixable. What are the full specs on your setup. Car, flash, mods, location or anything else relevant. Lets get to the bottom of this.
@@ZeroTo60Tube I live in Australia so it's a euro spec. However when I use RFP its maps I don't get this code, only when I switch to MHD. Only mods are msd81, new index 12s, fmic, ngk plugs stock dp's. And also 2A2C code. Bmw e90 335i
Anyone compared v5.1 stage 2 vs v9 st a ge 2+? I got both dyno'd. V5.1 definitely has more low down power and torque. Similar top end compared to the v9.0. Have others compared versions?
We haven't tried v9 on anything yet. But would like to give it a go at some point. The plan is to wait for the winter months. Its just so hot here in summer and it would increase the risk with the V5.1 maps.
@@simonpaton2168 5.1 uses desensitised knock tables. So the car wont pull timing so aggressively. It's the timing pulls which make the other maps feel slower. This car is near stock and we are quite warm this time of the year in QLD, not to mention Aussie fuel isn't as potent as the US. All those things combined make the chance of knock more likely. But in the colder months or when this does get its cooler fitted, we will give 5.1 a go.
Cant thank you lads enough, So happy with V9 MHD. + Great video, keep em coming !!!
Gotta get that cooler done next and stage 1 plus 🏋️♀️
n54 dumps oil when reving above 6200 rpm, you could be blowing burnt oil on your exhaust solenoid. Most shift at 6200, there's less torque above that.

The biggest thing that makes a difference is how you get it off the line. It's a very fine line between getting traction and accelerating vs too much wheel spin. The vbox has been so good for seeing what actually works.
Stock LPFP? Looking into Precision Raceworks stage 2. Let me know what you think. Keep up the content!
I've done a couple of DIY fuel pump upgrades with the walbro 460s and modifying the mount in the stock bucket, in all honesty if i had the money for a decent one like the race-works stage 2, i would jump on it. If you have any other questions let us know. Done quite a few mods to a few N54s now.
Hey guys I have done version 9 yesterday and my car started to hesitate a little in high gears it may be that my car is adapting to the tune ? How long was yours not performing perfectly? I’m thinking about going to version 8
Hey Lilsims, I think read last week that it can take up to 100miles for a car to fully "adapt", however you should see pretty close to normal behaviour with in an hour of driving. There were a few people that commented on the first vid we put up about version 9 who said it took 3 days for their cars to settle down. So let us know how you go.
Drive sensibly in the mean time and if you are doing any wot runs, try and log them so you can check everything is running safely.
As we mention in this video, if your car doesn't sort itself out, it will be a warning sign that something hardware related is on the way out.
@@ZeroTo60Tube Hey, I tried V9 yesterday but felt a bit jerky compared to V10 which I have been using, had tried V9 cause I ready somewhere that you won't get throttle closures, which I have been getting with V10 albeit it is imperceptable..what parameteres would you say the cars "learn" or "adapt" to? timing? wastegate duty cycle? etc?
@@dextershumba7262 The DME adapts to everything. Every sensor is used in its calculations and reflect what it does. It has targets to meet from the calculation and it will escentially adjust sensor data minimally to meet those targets. Thats what the adaption is. Throttle closures are not the end of the world, assuming you have an accurate boost reading. The tune is made for cars up high in Colorado and at sea level. The same car with the same tune in those 2 locations will make a big difference in boost levels with the same targets with the tune. If the sea level car exceeds the boost limit it will close throttle. Also if you remove a restriction in the inlets, it will do the same. The turbos make boost easier and over shoot boost target. If your hardware is spot on run the latest maps. they will work better. V10 is the most complex map and will be smarter with how it makes power. However hardware has to be in good condition. If v9 is better, you have a hardware issue that V9 can't see with is more basic tuning.
@@ZeroTo60Tube sincere apologies for not having seen this till now alas. I am always going through your channel and referencing videos and comments for the sake of learning and understanding the platform better. Apprecite the shring of knowledge, it really makes sense and ill keep tht in mind. Jut got BMS intercooler so going to be messing around with some maps and see what the car likes best. I'm still blown away by Christians 10sec 17t e40 run. I have some "questions/thoughts" ref ots maps nd upgraded turbos.
Here to feed into straight pipe!!
mufller delete of full straight pipe please. Just don't throw the exhaust bits away. You might want it quiet again at some point.
Great video but where is the datazap link
u guys should make a book about n54@@!!!
How's Dylan's BMW has not been on your videos in a long time?
Dylan is getting very annoyed that we keep buying other cars..... he has downpipes, LPFP and a few other bits we are due to fit and get it up to stage 2 plus. Will be on the channel very soon.
Awesome guys, not so good I now need to decide between keep my JB4 or changing to MHD 😳
I have a custom tune and jb4, plus fbo no mhd fbo in my town can beat me.
Richard Hill, you should definitely be running a MHD back end flash with the JB4 at least. The JB4s are brilliant if you are a self tinkerer. But if you aren't playing with the extra features of the JB4, you might not need it. The JB4 is a brilliant tool, but it is probably overkill for 80% of the N54 cars out there. I'm keeping mine, but i want to go big with power. If you have things mods port injection, the JB4 makes a lot of sense.
Hey Frankdogg, you are living my dream. Who did the custom BEF?
@@ZeroTo60Tube a custom race shop here in GA, called solo motorsports
How about the MHD N54 V10
Ken who writes the MHD n54 maps is now a zeroto60 member and he has been telling our group about how good these V10 is. Not only the tuning side but the way MHD in the back end works has some big improvements. 100% get on v10. If the car is in good mechanically condition and stock turbos it will be the best it and smoothest its ever run.
But don't just turn it off before the test, have it off a mile before the test. Or just don't run it until your on the way back home with it.
It is wayyyy too hot in QLD to not be using air con right now haha 🥵 🥵 🥵
@@ZeroTo60Tube dang...
These fuckin cars are so hot. Almost makes me upset i bought an f30 n20
Alpina Flash or XHP or Stock for Automatik?
This one is stock, we will be doing a transmission service, with the bridge seal replacement soon. Once that is done we will get on to XHP. Well thats the plan anyway.
@@ZeroTo60Tube very nice Plan👍 good Luck
Guys those times are not right . I’ve done exhaust Down pipes, jb4 tune , air filters
5”stepped Intercooler and Nanking AR1 and on 8psi got 5.1 and on 12 psi 4.5 , on the e85 tune at around 17-18psi I clock below 4seconds every time best at 3.7sec
I’d be looking for what’s wrong cause those times are way high,FYI all my runs are with traction off altogether,I’m. not trolling u guys just trying to help but I’d be checking for a boost leak , plugs and anything on the cold side,
They are amazing times man, assuming you are talking about street times not on a prepped surface, the only people i see getting those times on the street are using a very optimistic timing device (meaning they are wrong) or all wheel drive. Have you ever used a dragy or a vbox to get an accurate time? Let me know your dragy username if you have one would love to check the verified times out.
subscribed!!!
Thanks man!!!!
Aren't these cars supposed to run 0-100 in under 5 seconds stock?
This car, with 2 people in it, on this particular road was around 6.6. The factory claimed times are very hard to get in real world scenario.
We’ve done around a 1000 timed runs now and not much gets close to claimed times. And even when you add power it then becomes a battle for traction on a crap surface.
5.8 secs is factory time,
Under 5 secs you would need Stage 2+ car.
Main issue is traction, once it grips, it rips.
Lol
yes..its time for a straight pipe
I wish you would try these tests with the air conditioning off. It kills my n54! I bet you hit 4 seconds!
Some cars we’ve tested it makes a difference but the 335s are already on the edge of spinning the tyres and losing traction so it didn’t really make a difference in 0-100 time. Maybe top speed would? But it definitely doesn’t take half a second off the 0-100 time... unfortunately. If it did I would never run AC 😂
@@ZeroTo60Tube lol 😅
I agree, aircon kills my car, and I've had a 135i and 335i both N54s...
@@Richard-ck5zk Out of curiosity, have you ever actually measured the performance difference back to back with something accurate. I fear placebo may be having an impact here on what you are feeling. Dont get me wrong on a car with 100hp yes, a/c is a noticeable. But on something with getting on close to 400hp the 3--5 hp the compressor draws would be mighty hard to pick up on. Also like i mentioned on your other post nearly all modern cars cut the ac compressor off past a certain rpm point.
@@ZeroTo60Tube I've done it down the 1/4 mile, was a while ago though. Can't remember exact number but it averaged out to around a half second
Has anyone used the v9 maps for road course racing? Any issues? I was thinking about running the v9 91oct map with race fuel just to be safe.
I can't comment for road course, but think you'll be fine. The most important thing is get it on the car and do some logs before the event. You dont really want to be running an untested setup on race day. Do the prep and make sure the day goes smooth.
@@ZeroTo60Tube Yes that's what I'm doing now, logs look fine but I will go on a 30 minute backroad drive and log again just in case. Also, have the rfp v13 maps but they might be too aggressive and create too much engine oil heat. If nothing works I'll run stock map or stage 1 until I get a custom map. Thank you for your feedback!
@@in54ne82 Fingers crossed for you dude. Sounds like you have it under control. Honestly both v9 and rfp should be safe. Its really just a matter of keeping an eye on any hardware faults that may be arising.
@@ZeroTo60Tube My previous track days had no issues on stage 1 rfp boost by gear maps at around 70F degree weather, 20 minute sessions. This time I'm commuting 2.5 hours away then beat on the car at a 90F to 100F degree weather maybe more then I'll have to drive back. That's why I was mainly asking lol I'm a little nervous not gonna lie. For sure I'll keep an eye on my logs.
There is a V9?😳
There is and it’s definitely a bigger difference between 8 and 9 then 7 and 8.... worth a try.
since when? Alright thanks, I'll try👍🏻
@@xXPred4torXx Let us know how it goes on your car and what you think of it.
Zero To 60 hmm the v9 feels much softer but the performance remains the same.
@@xXPred4torXx Out of curiosity how did you measure your performance difference? You can see in the vid, i think it's going to be quicker on 9 but i was really sure. I've done around 400 0-100kmh in the last few years so my but dyno is little more sensitive than most and version 9 still took me by surprise.
Do you get the 2A18 code?
No, however our Australian cars don’t have e the DTML system at all.
@@ZeroTo60Tube I always get this code with mhd
@@tuiwilson5486 It will definitely be fixable. What are the full specs on your setup. Car, flash, mods, location or anything else relevant. Lets get to the bottom of this.
@@tuiwilson5486 Also are there any other codes coming up at all?
@@ZeroTo60Tube I live in Australia so it's a euro spec. However when I use RFP its maps I don't get this code, only when I switch to MHD. Only mods are msd81, new index 12s, fmic, ngk plugs stock dp's. And also 2A2C code. Bmw e90 335i
Anyone compared v5.1 stage 2 vs v9 st a ge 2+? I got both dyno'd. V5.1 definitely has more low down power and torque. Similar top end compared to the v9.0. Have others compared versions?
We haven't tried v9 on anything yet. But would like to give it a go at some point. The plan is to wait for the winter months. Its just so hot here in summer and it would increase the risk with the V5.1 maps.
@@ZeroTo60Tube what's the problem with the v5.1 mapping? Is it around 12 air/fuel ratio?
@@simonpaton2168 5.1 uses desensitised knock tables. So the car wont pull timing so aggressively. It's the timing pulls which make the other maps feel slower. This car is near stock and we are quite warm this time of the year in QLD, not to mention Aussie fuel isn't as potent as the US. All those things combined make the chance of knock more likely. But in the colder months or when this does get its cooler fitted, we will give 5.1 a go.
Let me know when you give v5.1 a go. Cheers
Simon Paton I’m running v5.1 Rn dnt know if to run v9 I just want the fastest map lol I’m in Miami Fl tho so it does get hot and I run 93 oct
Dude just straight pipe
