TBA (Throttle Body Adaptation) reset???

hyperzulu · 08-11-2014, 02:46 PM

Did you guys buy off the lot or custom order? Just wondering if the cars had been driven by others or not...

Lot. But to be clear, MY car is an N55 135i, not a M235, but theyre the same engine and basically the same fuel control (the M235 has the PPK tune from the factory, whereas it is an option on the 135).

it's the button at the end of the throttle...

you can try with the car turned off... just push all the way and then a little bit harder you will feel like a click

custom.

I think the kick down is for autos only?!? I have a manual.

manual or auto?

or ultimately, is this simply updating where the throttle senses WOT/flooring it?

The main thing I noticed (and the reason I did it in the first place) is throttle response. Like blipping the throttle for rev matching. Just sitting in neutral and tapping it - it wasn't responding like I thought it should before. It felt like turbo lag was excessive compared to what I had gotten to know from the car early on. So I did the reset, and...instant improvement exactly where I was looking for it.

I don't know if it pulled harder, but it felt like it was quicker to start pulling hard once I got on the throttle - like it used to be.

curious if you have a manual vs. auto as well...

Yes of course... only for the auto......

I guess that answers my own question... else you wouldn't be able to the the reset for the manual

Manual...the way it should be. ;-)

bubsterino · 08-14-2014, 03:55 PM

interestingly enough, i found that when i tried a reset again, it actually made the throttle response worse...i'm going to simply drive it more aggressively over the next 50 miles or so as suggested by some others to get the throttle back to expecting a lead foot :-P

as a question to all, i've heard that the car should be smoothed into open throttle - however, i want the car to pull the second i hit the gas - when you "floor it", do you do it quickly or smoothly?

did you notice your "boost" only lasting a day or so?!

Sorry for resurrecting this thread, but I didn't see any more recent ones that were relevant.

I was searching for topics related to TBA and ATC, and I came across this: http://www.bimmerforums.com/forum/sh...0#post16506160. It seems to definitively state that driver state is not stored, and that the reset should only be carried out as a maintenance task.

Is that now outdated information? If so, can someone point me to the newer stuff?

I took my 228 in for service recently and all the service guys told me it was bs. that said, I am personally convinced that my car drives like a bat out of hell when I do the reset as directed. I've found tons of posts to the contrary, and minimal posts confirming. never dyno'd so who knows.

I've read through a ton of threads on this for older models, but was curious if this was applicable for the new 2er. The procedure goes like this:

- Put the power on but do not start the engine.
- Floor the throttle for 30-60 seconds
- Keep the throttle to the floor and put the power OFF
- Release the throttle and wait 2 minutes.

During the 2 minutes you should feel or hear some kind of mechanical sound. That should tell you the reset is complete.

Anyone have thoughts on this? True vs. placebo? Does it work on the newer models? Thanks all.

Do you Press the start button once or twice?

I notice a similareffect after going from regular commuting (comfort) to a decent bit of spirited driving in sport. when I go back to comfort, it is closer to the sport-type responsiveness, less of that soft onset. I think I'm spoiled by now to call it 'lag' because it is more like a short period where it acts like a car with a hot 2 liter NA motor, not the old LAG that felt like a low-compression bus engine. The recent nostalgic articles about the old RUF and the 930s have made me remember a bit about what turbo lag really used to mean (especially w/ the 5 speeds, keeping them above 4k was not really compatible with those pesky traffic laws - but a buddy of mine actually dodged a ticket by showing the cop where the manual stated something like 'engine damage will occur if operated below 4000rpm').
