Holy Crap you guys.....sneaky ECU reset WORKS!!!
Figured what the hell, and gave it a shot per the instructions someone posted. I get her out and punch it from a start and it feels weird....a bit unstable. I am like great, I broke something, then I realize it is pulling like a friggin freight train and my a$$ is wiggling. I can't wait til the ECU sets me up this way....maybe better, that would smoke.
Anyway proceeded to do some launches and I can really tell a difference in shifts. Someone said it best....feels like the car had a tune up or something.
I COMMAND all of you to try this (well if you are not happy with your current setup). I just know now my car set me up wimpy due to long highway miles after driving back from Klee. Enjoy!!!
1. Turn the ignition key to the on (not start) position.
2. Press the gas pedal to the floor and hold for five seconds.
3. Turn the key to the "off" position (don't remove the key), then release the gas pedal.
4. Wait at least two minutes for ECU to reset.

Jak...what type of launches did you try after you reset the ECU?
1. ESP on off?
2. Mode? Sport/Comfort/Manual
3. Jam the accelerator vs. Slight pump, then jamming the accelerator to the floor?

Jak,
Do you have an aftermarket ECU? Would it reflash that somehow? Your stock ECU + Nos if I am correct?
I used to pull fuses in my Supra and it would make a BIG difference, similar to what sounds like here.

I printed the protocol out but have yet to try it. Who figures this crap out?
I will definitely try it before the ride home tonight. I hope I don't lose K2.

The ECU reset procedure only erases the ADAPTIVE transmission & throttle settings. It does not erase any of the fuel/timing or other programming.
I've been doing this since I had the car, only I was doing it the hard way; disconnecting the battery terminal overnight. This procedure described is what the techs use when they want to reset those settings.
It works great, but, as soon as you get back into a pattern of slow, constant speed driving, it will go back and you'll have to do this again.

Sooo...this procedure--resetting ECU--is a function of "tuning up vehicle"? Similar to A/B service?....So, how often do you do this?
....Please forgive me for my lack of knowledge and for asking many questions...
Will it, then, reset my A/B service reminder?
How significant is the difference of feeling and/or driving, afterwards?
Lastly...This process is applicable to which model(s) & yr?
Thank-you in advance!...I'm fascinated w/ your finding--thank-you for sharing!
Kind regards,
Reynaldo

On a car like an OBDII E36M3, the reset can be good for 5-7 hp. An old trick some of the M3 tuners used to do would be to dyno a customer car, bolt on a useless mod and then re-dyno after resetting the ECU. Guaranteed 5-7 hp.

You are obviously a man of extraordinarily good taste. Carry on.

ok, so I just did it... is there any confirmation of the reset? Do you just assume its done? I just drove the hell out of it and it chirped in 2nd gear with traction control on... conicidence?
Maybe its my new tinted tail lights making me feel faster...

This car just rips up the tarmac and the orange ESP light (which I hardly ever see unless I am taking a sharp corner too fast) stays on for 100' in a straight line after launch! I really struggled to keep it on a straight and narrow on a suburban street.
From now on, every night after parking my car in the garage, I am going to
"tune it up" so it's ready for the next day! Thanks for the tip!

I guess the big question this leads to is.....
When the tranny ECU learns the radical pattern (the drive like you stole), will it adjust and make even more power, or just lock the car in this already incredible performance pattern.
I am serious, mine is pretty dramatic. I am sure the guys already setup with the more aggresive pattern will not see a huge difference, but for geezer setup guys like me...WOW.
Like I said, a$$ wiggling on the thing.....felt like Beyonce.

now all we need is for somebody to come up with a ecu that keeps the aggressive driving ecu or a switchable to go from aggresive to smooth....

On-topic, I tried it with my S55 and it seems to work. After the 'reset' I drove like a maniac for a couple of miles of stop & go traffic, and the result is that driving away from a stoplight makes foor screaming tires.
