OK, so am I crazy to try this with my 2012 M35H? When in Sport mode it feels plenty peppy but that may just be the initial torque from the electric motor...

good to all , I'm trying to do this on my 2013 M37 sport , not having much luck . any help will be greatly apreseated.
thanks David

Worked like a charm for me on this first attempt. Def noticed a difference.

Any chance this would work on a 2012 m35h?

I'd imagine it will.

Did this today on my relatively "new-to-me" 2012 M37 and noticed a big difference pulling out of the garage. LIKe others have stated I did not feel my car was at all unresponsive prior to resetting the ECU, however there was a distinctly noticable chane in tip-in, shift point and and overall throttle response. Also before the reset I had noticed just a small and subtle difference between "Sport" And "Standard" modes--that has changed.

Do others do this periodically? With my Mustangs I would reset the ECU to clear the learned parameters twice a year--the Ford EEC-V system was much less complex anfd they were manual trasnissions. If somne out there are doing this routinely, any advice/experience re: frequency of same?

Can't stand the throttle lag some time its bad sometimes its not, depends on how I drive it....Is there a faster method than doing the pedal dance to reset the ECU? I was unable to get it to reset. I saw a video where he disconnects the negative battery cable and pumps brakes for a G35-g37 for check engine light. Or a tuner device that will do the same thing to reset the ecu. Also - If you have a tune like uprev or a tunner like bulludog does it remove the lag for good. several companies are offering a throttle controller thats supposed to remove the lag. link. https://jetchip.com/products-for-model/

I'm tuned with UpRev and the lag is still there, but usually happens in high heat situations like summer time. Not as frequent or pronounced once fall and winter arrive.

I use a cheap Amazon OBDII scan tool and the Torque android app to reset my ECU.

Greetings,

Just a question : when you say you notice a difference with the ecu reset, do you notice it in automatic mode only or does it improve also manual shifting ? Thank you.

Cheers

I do the reset twice a year (time change, smoke detector batteries & Infiniti pedal dance), or if I feel it needs it, and have not noticed any difference in manual shifting mode, which is always prompt and smooth (except for 3 to 4, which has a rough edge).

Since realizing how the whole thing works (ish), I have played around with it a bit and found that if you very judiciously use a mode (Sport only when flogging it) the car maintains responsiveness for many months - but who the hell wants to go without the sweet rev matching of Sport mode? I noticed this the first time (before I knew how to do the reset) when Snow mode was BY FAR the best/quickest/"maybe my transmission isn't broken after all!" mode when both Std and Sport were clearly in granny mode. I think the previous owner spent a lot of time at low rpm's, and I doubt the ECU had ever been reset - the car was completely changed the first time I did the dance.

Ok, thank you for the answer crrraaig !

What command/feature of Torque are you using to reset the ECU? I’d like to rig this up on my VLine.

Sorry, I should clarifiy that by reset I mean resetting the drive cycles using the clear codes function in the code scan screen. This may not be 100% the same type of reset as the one that is performed by the start button process, etc.

Is there anything that will show or tell you if the reset was successful, or will you just have to go drive it after each attempt to know?

Step 5 and 7 (blinking) should tell you if it was done right.

Gotcha, thank you.

Ever since I bought this car in 2016, when the temps get above 85F performance seems to lag, particularly when making turns to the right or trying to accelerate after a rolling stop. I've had the car checked by the dealer many times and also by my mechanic. There are never any codes posted. Ran across this thread and tried this procedure on my 2013 FX37. Unfortunately, it does not appear to work for my particular vehicle. Is there a different procedure to reset the ECU for a 2013 FX37?

I think just unplugging the battery for 24hrs or so should do a pretty functional 'reset'.

Guess I can give that a try though means a lot of reprogramming of radio, etc.
