Re: increasing throttle sensitivity in DBW? (not_too_shabby)

it caqn be increased thru the software in the ecu... most aftermarket ecu chips deal with that issue... but from what i have found drive by wire even with the chips or custom programming still doenst come close to good old fashion cable drives.

 

Re: increasing throttle sensitivity in DBW? (Image Dynamics Passat)

I wonder if the ecu adapts the throttle sensitivty. So if you drive like a grandma one week, you get reduced throttle sensitivity till you drive like a madman for a couple days to get it back.

 

Re: increasing throttle sensitivity in DBW? (not_too_shabby)

Maybe something changed with the 2003, or the V6, as my drive by wire throttle seems VERY sensitive.
The car is VERY responsive, but its a bit touchy when taking off, you have to really
pay attention to opening the throttle slowly, otherwise you burn rubber, get neck snap, etc. I would like to decrease the initial throttle sensitivity.
Maybe I will look into it when the bently CD gets here, and I figure out the hex-com....

Re: increasing throttle sensitivity in DBW? (Brett)

Interesting...... I came from a 2000 328i which didn't have the drive by wire. In 2001 they did. Anyway, it's taking me a while to get use to it. It seems that if you push on the gas, there is definitely a short delay and then like you say, it jumps off quick. It's not a big deal, but just something I'm adjusting to.

My 99 V6 is like that too. Too much quickness sometimes. The tip is adaptive though, so depending on how hard/easy you drive it adjusts itself.

The DBW on my 2001 with manual transmission is flawless.
