- Doc Harley from the Service Clinic at Low Country Harley-Davidson to help you with the health of your motorcycle! This week he talks about tuners- what questions to ask yourself and the pros/cons of different ones.
We know there are other tuners out there. These are the tuners Doc has worked with and had available for filming. Like the video says - make sure you talk with your tuner/mechanic about what they are familiar with and able to work with before buying a tuner.

I've been a Harley dealership tech for 25 years. I keep watching these videos waiting for Doc to say something stupid or incorrect. I'm still waiting.....
@@jif4639 . Yes...it will work on stage 1234
Maybe you can answer this for me regarding a tuner. I have an 2009 Road King with Vance and Hines power duals, hi-output and screaming eagle high flow air intake. Is was tuned by Harley and ran fine. Now I just installed an S&S 551 cams, pushrods, lifters, oil pump with cam support plate. I tuned it with the V&H Fuelpack with their recommended mapping but is running rich on the rear cylinder and smoked out my left pipe. What should I do? Thank you in advance.
@@falconator3419 with all of the stuff done I’d get it dyno tuned
@@jif4639 dynojet powervision is the best tuner hands down
He explains stuff really well.
I bought a 2020 and had a stage 4 kit put in before I got it, with the Harley tuner. The check engine light was constantly coming on. The dealership service department could not figure out what to do, they told me the Harley tuner wasn’t designed for tuning for max power and they recommended I take it to a Dyno tuner. The Dyno tuner told me it was a waste of money to try and tune with the new Harley tuner. So basically Harley took money for an upgrade and tuner that they don’t allow you to use full power. If you go to a tuner that allows you to use full power they flag my warranty. A $5000 “gotcha”from HD. Thanks for the explanation of how they work, very informative.
Absolutely the best explanation of tuners I have heard. Thank you, Doc.
@Shark GUA qqq1¹
Uúuuúuúuuuuuuyúuuuutyuoyoouyo
Doc, that was the most informative explanation of tuners I've seen. You definitely have a knack for putting it in layman terms. Many thanks for your great videos. Always learn something watching them.
Yeah, he does a good job with these videos.
This is a FANTASTIC video and very cut and dry!!!!!
I've had a ThunderMaxx on 2 of my Harley's and it never let me down. That's the only tunner I'll ever use. No matter you want to do with your bike that tunner can and will handle it....💯😎
Magnuson-Moss Warranty Act. They have to show you proof that what you put on the bike is what caused the problem before they can deny the warranty and your also allowed to have your certified motorcycle mechanic look at it to not just Harley and also doc I do love watching you videos
POWERVISION FROM FUELMOTO USA...BEST IN THE BUSINESS.....30,000 miles on my 2010 107 build 116/126 not 1 hiccup !!!!
ThunderMax 😎 it's on a whole different level
@@DeuceRollinChainSmokin in which way? I have a 05 fxdi pre o2 system and debating between both systems.
@@LiTLflor self learning and it tunes itself with wide band o2 sensors. You can tune out literally anything about the bike. It literally teaches itself how you ride and what fuel/air suits you best. Powervision is a close 2nd but it's limited in some areas. ThunderMax is a better option if you are BUILDING a monster. Cams, intake and exhaust get the PV. Doing compression heads and the full works get the TM.
Thank you so much for this great video. Just bought a 2020 Low Rider S and put Vance & Hines mufflers on it. So glad to hear I don't need a tune!
The Magnuson-Moss Warranty Act (P.L. 93-637) is a United States federal law that governs warranties on consumer products. The Act also makes it illegal for companies to void a warranty or deny coverage under the warranty solely because an aftermarket or recycled part was used. An aftermarket part is defined as a part manufactured by a company other than the original vehicle manufacturer or original equipment manufacturer (OEM)
Quoted several times but irrelevant in real life…..Doc
My California dealer fully honored my extended warranty with the V&H FuelPak, after a major electronics failure in my 2016 FXDB. I asked if the tuner will change the warranty, they said, emphatically, no. Nice thing about the Y&H, is you can switch back to the factory ECM tune, at will.
I've had Power Commanders on HD's for years with no problem. I've never seen any of the issues with it you have noted. My latest build I used a TTS and yep, it is a much better tuner than the Power Commander, but like I said, never had a problem with the Power Commander and I've used it on 3 bikes so far without issues.
He is selling the Harley product. In other words he is full of the ---------.
@@semperfipar1299 what part of this video was he selling the Harley products? The only part I saw was if your still under warranty !!
So correct me if I am incorrect here but basically what the doc stating that harley davidson ecm will shut down after year if PCV was installed fooling ecm?
The Doc is a very good teacher. Explains well and knows his stuff. Thanks
It's scripted direct from Milwaukee
Warranty makes zero difference. Unless they proof your changes caused the issue they have to cover it. FTC slapped Harleys hand for deceptive warranty as they should. Failure analysis has distinctive failure Moses that are identifiable. This warranty is only as good as your dealership. This is why I only buy bikes from Family owned dealerships and avoid corporate owned Harley dealers. Bottom line since the FTC slapped Harleys hands with their warranty policies applications the game has changed.
2010 Superglide with a stage one only. I used a Fuel Pack with the Android App. It was super easy and took literally 4 minutes. It took a typically crappy running Harley and made it run smooth, and stronger.
Great video Doc. Thank you. All this makes carburetors look easy.
Doc, your knowledge doesn't cease to amaze me. Thank you
You are an absolutely fantastic doctor. Very well explained. I ride 2019 slim in London England 🏴 now in know what to choose without voiding my warranty. Cheers
Great Info, Thank You, Had a Zippers Injection Kit Put on My 01 HD Road King Police, it comes with the Thunder Max,talk about night and day. I have a Great Tuner locally.
I really enjoy hearing and seeing their guys with the exotic bikes. No doubt they are getting a lot out of their machines.
I believe the design team contemplated most of what a bike could be subjected to by us consumers and planned accordingly. Here in Arizona, a guy could have a long walk if he needed help. Likewise, I have never asked a gunsmith to “improve” a firearm. Sometimes it is good to have dependability as a performance goal.
Doc thx you nailed it now I understand exactly what I need.
I remember the days when you could spend 500 bucks on a set of pipes an air cleaner and some jets, i miss carburetors
I've got a 03 Harley don't have an O2 sensor on I have a Cobra FI tuner and it works just fine I've had it on there since 2003
What Bolt-Ons are you running? I have True Duals front to back and a Ram A/C.. Unsure of going the Fi2000r route or if I have to go up to the more expensive ones because of the True Duals. I do not intend to do anything further to the 01 Road King motor.
Great overview of tuners. I had read the ThunderMax tuner isn’t compatible with the RDRS system. I’d love to hear how these tuning companies will deal with the RDRS system in Harley’s.
I don't own a Harley, but this video has so much information great stuff. I enjoyed watching the whole video.
"Black Flagging" customers motorcycles, one more way that Harley is destroying it's customer base.
Well. I for one understand them. If you use a tuner that will change the signals from the HD system you don´t know what will happend to the bike in the long run. So HD don´t want ppl coming in saying something is wrong with their "stock" Harley... It´s just comon sence for a Company. Protect your Product.
None HD tuner that is..
This was a required action forced on Harley when the Obama administration's EPA sued them. They got backed into a corner and had to agree to this practice as part of the settlement. I think John Maxwell explained it pretty good on one of his videos.
Hey Doc DK Says you don't need a tuner with slip Ons and air cleaner cause they did a sniffer test and the Harley Davidson M8 factory tuning is rich enough!
So you're saying, if I swapped my exhaust from stock to v&h short shots or big radius while keeping the stock air cleaner, I don't need to tune? Not even with an FP3? I have a 2019 sportster 48.
aDRIAN pAMINTUAN Yes.
As long as your ok with the decel pop you will get then ya dont need one.
Think of your engine as a big air pump which is restricting suction with the use of a stock A/C. Just because you add some sound doesn't mean you're pulling in more air. Exhaust only will change scavenging and may even hurt performance, probably not much if any depending on type.
Going back to the 10% with mufflers.... what about drag pipes with stock air cleaner and stock tune. Am I still safe?
Fuel pak 3 for me love it best part if you need assistance the vendor is only. Phone call away send them the map they tweak it you use it and enjoy the results.
yes .. they are great.. and like you said.. you can download map to your phone and since its a smart phone you can send them the map and info on bike . they tweak it, send it back and you can then flash your ECM with the tweaked map.. also it can hold a few Maps in memory..
The bad part is that is not stable. The values change to previous ones in a random base, and populate large tables is a very uncomfortable thing. Both is from my personal experience with the FP3 after I do a little biggest change in my bike. Now I need to purchase a PV-1 and all is more easy and works as expected to works
FP3 is a good product, but V&H tech support is terrible.
sounds good for d.i.y noob like me
great video doc iam just now getting into the world of tuning and boy let me tell you it can be so frustrating getting this stuff right.sometimes i really miss carburetors.
Fool me once
Shame on you
Fool me twice
Shame on me
Fool me three times
Its time to Change brands.
I'm starting to rethink getting
an aftermarket exhaust.
If the exhaust didn't look
so hideous on my Fat Bob
I wouldn't worry about
changing it out.
I like the Vance & Hines
Slash cut short shots.
They look & sound
Awesome!
If your gonna spend a lot of money on a full exhaust system. Go with a 2 into 1. They provide better performance than any duel exhaust system.
Wow, bring back the carburetor I say. Good video Doc
Great advice , Doc , thanks . I don’t think I’m going to mess with mine for now . I don’t feel ready to open a can of worms .
That is absolutely not true. The Magnison Moss warranty act does not allow Harley to cancel or deny a warranty because you used aftermarket parts. The burden of proof is on Harley to prove the part you installed caused the problem. Sorry Doc but they can’t delete your power train warranty as they please. This BS is put out all the time by the dealerships to scare you into using only Harley parts. If Low Country Harley is doing that to their customers then they are lying and violating the law. I like the videos Doc but very disappointing you are mis leading on warranty information!
So what do I do when the Big Red Screen comes up, sends HD the message, This VIN is modified and forevermore when we call HD for warrenty coverage they say, It shows on our screen this bike has Non HD parts......Doc
@@LowCountryHarleyDavidson you don't have to do anything other then follow your employers policy. But he is right in which harley must prove how the after market part caused the failure. It's is a battle that will eventually be fought in court.
Just adding slips ons and air. Should I just have the dealer re map?
That was clearly covered in in the video.
Emil George people just don't pay attention
At the 2:15 mark he does start to address the issue of adding exhaust and an air cleaner. He then talks about needing a turner. However, I believe there is a less expensive option that he omits and that is the dealer downloading a possible map directly to the ECM. This is usually less costly than buying a tuner if H-D has created a map for the particular exhaust and air cleaner that you are using. Not sure why Doc didn't elaborate on this option.
OMG for once an unbiased opinion towards one or the other just the truth thank you so much I just got the fp3 tuner and s&s header and I thought the map I downloaded would be the fix all now I know I need to get to a tuner to get it finished off correctly thank you for this valuable information and I did subscribe to you
Thanks for taking the time to watch...Doc
The only thing I put on my bikes are miles.
Well that cleared up a bunch of questions....thanks doc.
Doc your great love your videos but Harley just wants to over charge you for there crap💩
Excellent video Doc, but what I want to know is who the hell thumbs this down...
Just ordered a new exhaust. Good to know that I don't need a tune because of the sensors ! Thanks Doc !!
No, you don't NEED to tune, but even a stock bike will benefit from a tune by a tech that knows what they are doing.
You mentioned needing a tuner after changing the air cleaner and exhaust. I swapped the air cleaner, but kept the stock box and changed to aftermarket slip ons. I still need the Harley tuner to maintain my warranty?
You are asking the wrong question. HD warrenty covers HD part snd Service. Will HD cover all Harley-Davidson parts and accessories? YES. How can Hd cover aftermarket parts?……and yes I recommend a tune after your modification……Doc
Also you need to call and ask your performance parts company and ask them what tuner works best with their product. Example: Rhinehart recommends Power Vision... and man does it work!!!! Bottom Line have it Dyno Tuned
I have a question. My dealership installed an aftermarket headpipe ( Tab 2-1-2 ) and Tab exhaust and of course I upgraded the air cleaner and they used the Screamin eagle pro tuner and also their tourqe cam.they are saying I don't need a dyno tune . what are your thoughts ? I don't need to squeeze out every little hp .
In my humble opinion, they can believe your tune is close but in fact a custom dyno tune can deliver a better ride…Doc
Doc , Thanks for breaking it down for me and the rest of us weekend warriors! Lol
Of course if HD's own tuning devices can accommodate you all the way to stage IV, that's the way to go and it's guaranteed to work!
It's a restricted/limited EPA parameter tune.
That's also why the 131 kit includes a headpipe with a cat. For epa.
And.... why the HD 131 makes smaller torque and hp numbers vs. aftermarket big bores (with even smaller cubes).
Add to those 2 limiting factors, that HD cams are also often lacking in performance compared to some aftermarket cams.
@gemini232003 Exactly. Harley marketed their tuner as an aftermarket "race tuner" AKA:Non EPA Compliant, just like the other aftermarket tuners. Where Harley differed from the other tuners, is that Harley Davidson Motor Company was an oem vehicle manufacturer and although they didn't authorize the installation of that product on street bikes, their dealerships were installing the "race tuner" on street builds. As far as the EPA concerned the MOCO was turning a blind eye to the dealers circumventing EPA regs. Harley ate that fine for the dealerships. If they hadn't, it might have seriously jeopardized the long term viability of many of their dealerships. As part of the agreement Harley stopped selling the "race tuner" and now you just get the street tuner which only has canned maps which are epa compliant, which you can't edit. Which is one of the reasons that the dealers like to sell you a Smart Tune Pro if you stray away from stock or screaming eagle parts, but want to keep your warranty.
@@pR1mal. I gave the current SETuner software and you can edit you maps. It is fully tunable. But it is limited because of the narrow band O2 sensors. But you can tune it. I bought the Fuelpack when it was not fully tunable. And now they have the Pro version.
@@jobeta22 Thank you. I had a FP3 on my 14. What is the richest AFR you can set in the SET software?
Thanks for the very informative and honest information!
As for the newer riders. Welcome to the mystique of upgrading and tuning your rides. It certainly comes down to each person's level of upgrades, ultimate goals, and finished project.
Ride safely and as Doc said, investigate, educate, and realize what your end goal is, before purchasing some things you may not need or won't be compatible with what you want to accomplish. Also, make sure you have plenty of cash in your "Hog" bank.....lol
FTW
Excellent advice! After initially changing to mild slip ons and the HD torque cam with the HD tuner I wasn't happy with the results. I did a lot of internet research and thought Thundermax might be the right solution. I ended up going to a local shop and he recommended the TTS tuner and explained why. I changed my setup to a D&D 2-1 pipe, Redshift 472 cam, bigger air cleaner, S&S manifold, etc and went with the recommended TTS tuner. The end result was a bike that runs great and suits my riding style. My takeaway was exactly what was suggested in this video, if you're changing your tune, talk to the person who will be doing the work, they know what works for them.
Thank you for your testimony…..Doc
Thank you Doc.. That was so informative and helpful.
Ride safe from Sydney, Australia 👍
I have a 2011 Ultra Classic with no changes and it runs perfectly. What can I say?
If it's not broken, doesn't need fixing.
you always right sir
I appreciate your kind words….Doc
Power vision with target tune. Went from 103 to FM 107 with level b heads to a s&s 124 and never had an issue or had to see a dyno. Simply get a base map and tune.
Ur the best EXPLAINER so far!!! Thxz!!!
Glad you think so!..Doc
Powervision is the best out there. Can only be beat by a tuner and his dyno.
yeah i was kinda surprised he didnt talk about PV.. arguably in the top 2 tuners on the market
Yup.. im a power vision guy..
Thundermax is the best by far.
Power Vision beat out my experienced dealership dyno guy using a Harley Race Tuner. Thanks Fuel Moto.
So if you buy a used bike from Harley with a ESP and the bike has a aftermarket tuner would you still be in warranty ? Million dollar question. Great video doc !
Wow! Finally a good overview of tuning. Your not trying to sell a product, just clear information. Now it's up to us on what level of tune fits pocketbook and riding style ..... thanks Doc.
He’s incredible, love his advice and information
Thank you...Doc
I chose the best ..... cheapest..... left it alone... stock. Let’s face it, Harley has enough of my hard earned money.
The best😂 you mean the epa compliant lean as fuck tune??? Lol
I have a 2011 tri glide with a stage one kit it was on it when I bought it I would like to have a little more torque I'm thinking of the se255 cam do I need a tuner
Yes Yes Yes..in fact your Stage 1 would run better with a good tune….Doc
Doc Harley is THE MAN!! GREAT VIDEOS 👍
This was an AWESOME video. Doc? Thanks, man. You’re a master!
By far the best tuner I use us the power vision 💪
Hi Doc' I do have another question? If I do change the cam, do i any tuner at all!! Just by changing the cam, and' putting in the S&S cam plate and oil pump?
Darrin you have been following a lot of forums and read the answers everywhere. Changing the exhaust is the number one game changer in a Harley tune 2nd is cam! Changing the cam plate and oil pump will not need tuning. Will it feel like your bike is running better, well yes but it has not changed the air flow in and out of your motor. People are always asking,” should I tune?” Tuning is an investment not a waste…..Doc
Great video! I like to hear more about the 4.5 screamingeagle street canons please!
Vance Burks I have some street cannons on my 2019 CV O Rd. guide the street cannons are nice mufflers straight through nice exhaust sound but not very loud the good mufflers but if you want louder you may Want to go in a different direction
Personally they're sub-standard at best. I "HAD" them in a 18 RGS with a Screamin Eagle Stage 3 build with FuelMoto Jackpot headers. Sound wise...I thought they sucked. Performance wise...eh. I used them plus the Pro Street tuner to stay in warranty and I got 114.3ft lb torque and 105hp. I just came out of factory warranty and installed the Vance & Hines Torquer 450 muffler and Zippers Redshift 468 cam and had it tuned using PowerVision. My numbers changed big time. I'm now pulling 134.97 lbs torque and 118hp. The Street Cannons are a Ford Pinto vs the V&H which are a Ford Mustang GT.
The Race tuner (the orange Harley one) is the equivalent of TTS. It used to be the best Harley tuner with no EPA restrictions but it’s hard to get one that is ‘virgin’ and hard to find a tuner that knows how to work them out
HD has made the original Orange box software not compatible. If you want to use this the New Software must be loaded into it which is now limited to EPA standards :(
Thanks Doc. Great information as always. Stock works just fine for me. Plus a little extra chrome here and there.
I had a power commander for 5 years, no problems ever on a full build.
Hey Doc thanks for the information it was great learned a little bit more about the tuners
Ok, so I got a full stage IV pro street on my 2019 1200 Iron... except for the pipes. Those were swapped for V & H grenades hi outputs.
Should I get the HD screamin eagle + the pro tuner with wide bands? Or the FP4 + Bosch wide bands?
Talk with your local tuner. In my opinion neither will give you the tune you deserve….Doc
@@LowCountryHarleyDavidson thank you
Why would I use tune on a bike manufacturer’s product that’s not capable to make a timing/cam chain tensioner??😜😂
they have not made spring tension cam shoes in 14 years get out of your parent basement and turn off fox news
j Eber I rest my case! Lol
@@1957eberhart MAGA
I realize fuel injection is the way nowadays, but if I have an older model that is carburetor and I change pipes etc. Am I only needed to adjust the carb or does electronics still make a difference when it comes to the performance of my bike? Thanks again and I will continue watching your videos for future topics.
Great information delivered in a no nonsense easy to understand format. Wish I had a local dealership that believed in this approach.
That's what I am up against
I have a 21 Road Glide Special. My service advisor at Harley told me that the 114cu already has a high flow air cleaner therefore me upgrading to the screaming eagle heavy breather would not require a tune. The Harley dealer installed my Vance & Hines torquer 450 slip one and my screaming eagle heavy breather without a tune and actually my bike seems a little faster. What are your thoughts on this.
For the DYI person, the DynoJet Powervision, ordered from Fuel Moto is the best way to go. They have many more bike, air cleaner/exhaust combo specific canned maps than the FP3. I ran the FP3 on my last two bikes & it's a great product. But not as robust as the Powervision & Fuel Moto gives an extra year of warranty & support is terrific. Just my opinion & experience.
I ran a Power Commander and FP3 on my FXDB and eventually went for the Powervision. When I bought my FXDLS the previous owner provided a TTS with it but still I cut the bs and went right for the Powervision this time like you said from FuelMoto. The unlimited map support alone is worth the money. PV is my goto recommendation for anybody regardless of how minimal they plan on going with their upgrades.
Agreed! PV on my FXLRS and honestly a litt;e annoyed they didn't mention it on this video especially considering it's neck and neck with the FP3
Great video DOC!!, Crystal clear
Another great video Doc! I feel that the Fuelpak is the way to go for 90% of DIY riders.
Agreed.
I love mine on my 16 SGS.
It's great for the person like me that cant afford to have all the upgrades done at once. A little here ,tweak, a little there ,tweak...
Dynojet power vision much more features....
BrewCityRider FuelPack sucks. Seen it burn up too many cylinders
@@@richardedwin5980 any one of them will do that when ya dont know how to use them properly.
gaknskk this is true but I've seen more problems on bikes using the FuelPack than I have using say TTS, PowerVision etc
This is probably a dumb newbie question.........if you tune a bike with one brand of tuner, can you tune it again later with a different brand tuner? Bought my bike used, was told it was tuned but i have no idea if it really was or what tuner they used. Can I just go pick a tuner and have it tuned with that? Just so I know it really has been tuned and with what. thanks!
Not a newbie question and a difficult to answer. A few tuners do lock out an attempt to add a different tuner. A possible direction for u is to go to a dealer and ask to hook up their digital tech lap top. This can look at your software and see if it has been tuned and the tuning ID. This does not tell you what tuner. Some shops can identify the ID. If you wanted to start from scratch. A dealer can download the Factory stock ECM program then have you choose the tuner you desire….Doc
@@LowCountryHarleyDavidson Thanks very much for the answer Doc. Very informative I appreciate that. Jeff
Doc, thanks for the good teaching.

This is the year and bike I have, it works good you say?
Hey Doc your the man bro but I’m new to the Harley life my question is how would you tune an older bike? My first bike I purchased is a FXDL and I love it no regrets but I want to keep it running smooth with a little more power.
A Harley-Davidson with Carb is much easier to modify. I am familiar with Dynojet Carb kits. Good instructions with parts that work. I do not promote changing the accel. shaft. the stock shaft with nozzle works well. Dyna also offers several options for adjusting timing....Doc
Just leave it stock & enjoy the ride !

Outstanding review of how tuners work!
Very well explained! Thanks a lot! My 04 Heritage had 2 mufflers installed, that werent ment for this bike, as it didn't use the interference pipe. So it was running terrible. I got stock us mufflers without the catalyst. Bike ran, as it should! Now as i sold it and got a honda fury, which the previous owner had the Powercommander V pfofessionalky installed and which has been tuned on a dyno by a professinal tuner, this bike runs soft and smooth with very little fuel consumption. I got all the documents and diagrams. As I have no clue about all this stuff, i highly recommend, not to tinker like a Teenager on a moped, but go to a professional tuner and let them do the work!
Excellent explanation, thank you!
So basically these tuners are good when you just add slip ons and high flow air cleaner, anything else added on like cams, heads, etc should be done by a dyno tuner. Am i correct on that or no?
You are BUT any modification would benifit from a good dyno tune….Doc
@@LowCountryHarleyDavidson , thanks for the info. I think im going to get the SE tuner because i dont plan on going any further than pipes and high flow air cleaner. Also are the other tuners EPA compliant now?
Good video. I have had the Harley tuner and the FP3 but in my experience, the best so far has been the Power Vision with a Fuel Moto map. Buyers be warned that the FP3 is fine for stage 1 but it has a very difficult time with stage 2 or higher...
Doc thank you for your work. I enjoy learning from you. Rumor has it that the 2021 / 107 doesn’t require a tune if you add slip ons and a more “open” Air cleaner. True? Or false? My gut tells me to get the tune - do it right and move forward! Ps - not looking for more power, just better thump in pipes.
I have seen DK Rumor too. I prefer to walk the Company's instructions...mufflers and air cleaner change= Stage 1 download....Just to be safe. Enjoy your Thumpen Harley...Doc
Just curious on what your outcome was I have same 2022/107 and want same ?
I get a kick out of these m8’s. guys spending huge money on kits but if it’s got a Harley tuner top speed is only 110 mph 😆
Mine is twin cam is limited at 160 mph with power vision
LMAO, 160mph on a Harley. That'll be the day!
Fred I didn’t say it will go 160 I said it’s limited at 160 mph. But it will go much faster than 112 mph that the m8’s are limited at.
dude, w/ the FP3 you can turn off that limiter. I walk on stock M8's all the time....the look on their face is priceless!
Jeff Helm
My TC was limited at 115 from factory. the power vision raised it to 160 mph. Not sure if the limit came from dyno jet or fuel Moto who I bought the powervision from. Are you saying a fp3 takes the limit of the m8 ? Because I heard you can’t override the m8 ECM. Don’t know if that’s true.
Hey Doc. Just bought a 2005 ElectraGlide Ultra that blows black smoke and pops and cracks on decel. It has Rinehart pipes and a hi-flow air filter aftermarket. I cannot find a tuner on it. I am getting a lot of conflicting opinions about what to do about it. Any advice (besides taking it to the Pro who knows his a** from a moosetrack)?
First remove the spark plugs. Look at their condition. Replace with OEM spark plugs. Run bike. Test for intake leaks. You’re a DIY guy I’m sure you and TH-cam will figure it out….Doc
Thank you Doc, it’s about time someone explained these tuners in a way most of us can understand. Is it true that after my bike is Dyno Tuned there is no need to touch anymore unless I get more work done to the motor. Rob in Australia
All i did was put a pair of 2inch straight down pipes on my Iron 883, im thinking the Vance & Hines fp3 is my best buy for the money. Comments?
I went with the ThunderMax....the cost of the TTS system plus to get the local dyno expert to tune my bike was very close to the cost of the ThunderMax. I did my research and installed it myself. No dyno required, and it is always searching for the correct fuel/air mixture for whatever conditions or altitude I'm at. From riding Beartooth Highway (14,000 ft) or on the coast it is in tune as opposed to the TTS where it "was in tune" the day you had it installed.
All the reason why you never buy the Harley extended warrantee if you buy a "USED" Harley!
Always try to get financing through your bank or credit union and buy the extended warrantee from them!
They are usually cheaper, and who's going to argue with you whether you installed the power commander or not?
Thanks for sharing your opinion and options...Doc
Always informative and much appreciated. Thanks again doc.
Datonatech, best service ever, you used to be able to tell them about the motor your building, and they would bench tune the ECM for you with no extra charge, not sure if it was because I was a dealer, or if the did it for everyone.
you shouldn't need a tuner. for the explosive cost we pay for harleys, they should be pushing 120 hp. out the door when new from the factory. just another way they stick it to us. won't buy another.
2 QUESTION FOR YOU DOC, WHAT HAPPENS IF YOU GET A USED BIKE, AND WANT TO SEND IT BACK TO "ORIGINAL" SPECS? DO YOU THINK THAT SOME PEOPLE HAVE A QUESTION ON THIS? I OWN A 14 SPORTSTER 883... AND THE ORIGINAL OWNER REMOVED THE BAFFLES FROM THE EXHAUST.. CAN THIS HURT THE BIKE OR NOT?
