2001 throttle response question?

Wow, thanks for jarring my memory. I threw this question at the Volvo press relations manager here in the US. He told me to check back with him and I completely spaced it. I'll call him back today.

Dear George,

Thanks. Could you find out if this chip can be ordered directly from Bosch.

I think that George should be able to get you the right answer to this question, but since all new Volvo's use drive-by-wire throttle management, it could be just be an 'ECU' change, but I am not really sure. It could also be a 'flash' done by the VADIS to the 'TCM', so there are two possibilities.

I have heard that all 02' model Volvo's have a different ECU significantly improved by Bosch. From what I have been hearing, the difference is so big, that all 02' Volvo act very different now. In this new setting, initial throttle tip-in is supposed to give a large fuel/air mix to compensate for the overall small displacement engines and slow spinning turbo from a standstill.

I have not noticed any difference in the n/a S60/V70s and S60/V70T5s. The changes were largely made in the 2.4l LPT engines and the 2.9 n/a S80 engine since both the XC the S80 2.9 did suffer from poor low-end torque. They are the only two engines that one can notice a difference. Although I like th quicker feeling, I kinda loathe the "jerky" reaction of the car, you have to really learn how to modulate the pressure on the gas pedal (from a complete stop) in order to avoid that type of jerky start. I really liked the "older" feeling, which was a smooth and predictable start.
