Electronic Throttle Adaptation reset procedures

that throttle adaptation works almost like the short and long term trim adjustments. You have some level of base maps and as you drive under low throttle or hard throttle it will update either or and use a variant of the two numbers to determine current throttle response. Obviously the more you drive under low throttle, the more it will adapt to providing lower throttle response. The problem with this equation is that adaptation isn't instantly and may occur over hundred if not thousands of miles depending on driving style.

Personally I have a 20 mile commute and part of the distance I'm driving slow with the wife and kids and the other half I let loose. So that goes with saying that my throttle response if not very good. Once I reset the adaptation, it seems like within 20 miles or so of "spirited driving" performance was even better. I'd say a once a week or week and a half reset is in order unless I've been doing quite a bit of foot mashing.

It's just throttle response... and i imagine if u drive with a heavy foot it would adapt as such...no need to do it every morning lol...

thanks for the info.....going to go and try it out now!

Hey guys.. I tried it with my 99 323i automatics but did not hear a beep. I tried the 1) turn the engine to the "on" position then pressed on the pedal to the floor 4 times. Does this flood your engine with fuel though?? The car did seem like it pulled harder.. but I thought it could be psychological. Anyone else try this with a pre-2000 model?

u deserve a m3 kevin man... if i had 4 i'd guve u one
good stuff... i havent tried.. but what if its all in ur heads peeps

Anyone know if this works on an M3? I commute stop and go every day and I had noticed a BIG drop in performance and acceleration ... I will try this when I get my car back if it works.

Yes give me a M3! Come on I know there's someone who has to much money and just want to give away their old M3 for a new one. PM me! or PM me and I will give you my paypal email to wire the money for me to buy a new one. It's what only $56k? That shouldn't be alot for you rich dudes.

Remember this is the real deal reset procedure from BMW! I will post the actual document later. It definitely isn't in my head. The reason I know is my little 18 month old girl in her car seat in the back When I had my MAF screens off and accelerated, she would say wwwwwhhhhhhhhoooooooeeeeee. I put them back on. nothing. Throttle adaptation reset, and she goes wwwwwhhhhhhhhoooooooeeeee! That's validation enough for me! (no I'm not really going fast, just accelerating through a light :smile

fun tip! After i press the return key im running to my car and trying it.

Just got back...It felt it pulled much harder throughout the gears!! Watch me do this at each stop light :-P Haha

I don't understand exactly what you guys are doing. Ignition on, off for 10 secs, then start the car, I get it, but then what? Drive fast? foot to the floor? maintain high rpm? for how long? I'd be stunned if it adapts to 5 minutes of driving. How long did you drive to notice a difference? I'm very confused.

i just did it. i think it's more responsive.. but i'm not sure if it's all in my head or not.

THis should work on all cars with electronic throttle control meaning some later 323 and 328's as well as all 325 and 330's.

I believe 323/328's that were built 10/00-12/00 will have electronic throttle control or what is called "throttle by wire". It is with this new electronic throttle that these 323/328's got the new mototronics that this will work with.

For the old models meaning prior to 10/00, I've been told that you can try turning your ingnition to the on position (not started) and press the gas peddle all the way to the floor 4 times, then you will hear a beep or something and that tells you it worked.

Hmm - my 00 328ci was built after 10/00 but it is mechanical throttle, not drive by wire. It was my understanding that it wasnt put on any 3ers until the 01 model year

I think some people are confusing the adaptive step software and the adaptive throttle in drive by wire. I can't explain the difference except that fact that per the BMW info my car with out drive by wire has the adaptive step listed. I do have the Dinan tranny software which over years has not been adapted away but i do not think the adaption is removed, just adjusted. Also, it definately does other thing beyond the improved responsiveness - such as changing the way the step works for me (goes to first at stops, etc)

I had to go out again and try it... I do feel like my car is going faster. Even if it really isn't.. my mind is playing good tricks..

Valerie,

In fact some 323's and 328's do have throttle by wire that were build at the end of the production cycle. This information is according to BMW not me and is referenced in thier technical information cd's. In addition, this production run converted to the new engine management with a 16 pin OBDII port instead of the older 20 pin DLC port.

Yes there is a difference between throttle adaptation and adaptive steptronic transmission. The procedure outline for resetting electronic adaptive throttle in no way resets the adaptive transmission software unless there is some easter egg proceedure like hold the brake and fart. If people are confused about throttle control versus transmission, then they probably should ignore this thread and keep driving. We are talking apples and oranges (throttle vs. transmission).

As far as i'm aware...your car won't 'pull harder'.... it will just increase throttle response if u drive slowly quite often.... ie. it will give u more power for less throttle travel; u slightly press the pedal and it'll give u more power. But if u floor it - same amount of power regardless of reset or not.

guess non of this applies to me then - the mechanical throttle is , no excessive travel, no need to reset

I agree. That's the feeling I have to. If I slightly press the pedal the rpm rises faster and higher. In other words little throttle travel does more. When I floor it the car feels the same. It's a bit the same as an X5. That car reacts aggressive to a slight press on the pedal. If i compare an X5 4.4 with my dads ML500 the ML has more power but doesn't feel faster because you have to press the pedal hard to make it go faster..

i did it this morning, this is a great tip! the car certainly seems more responsive.

Actually kinda annoys me....having it so responsive on such short travel....cos when u get to the middle there's like no difference lol...

How does all this effect cars with Sport button?

I would assume the sport button changes the throttle adaptation map?

Tarkan

When you say turn to the on postion, do you mean the second click for the accessories, where all the lighst on the dash come up, or the first click to where the ignition is on?
