BMW M3 3.2

Hi Simon,

I got my colleague, a former motor engineer, who has also raced cars to
sum up what the cams are like. I thought this would get the point across
with maximum impact!

Cheers,

Andrew

Chip re-flash - report

--------------------------------------------------------------------------------

Garry - Melbourne, as posted on the DTM Power forum.

After listening to many respected and not so respected opinions on "chipping"
the engine management system on the M3-3.2ltr.

Some respected ppl suggested that performing this mod is a waste of $$$, and even if done in real time with an intercerpor management system, perhaps lucky to reap 5kW at best, and there were others saying that the 3.2 is tuned very conservatively (compared to the 3.0 M3)and there is good power to be had, around 15rwkw, suggesting why the 3.2 feels doughy and flat compared to the 3.0, is mainly in the timing maps.

The lure of potential hidden kW was just to much and I decied to take the punt, as the chip tuner offered me a 7 day money back no Q's asked condition.

The proceedure took about 3hrs, and im happy to report, that there is a significant differece with the new engine software. Firstly the engine feels more "alive" and respods well to low throttle inputs. It seems more flexible as well, pulling without protest 40-45km/h in 6th on flat ground. At full throttle it revs with more urgency, and it keeps pulling to the extended rpm cutout. With the sticky tyres ive got there is a nice chrip on the redline 1-2 shift (which wasnt there before), and 4th gear overtaking responce is certanly better.

Id say based on the right foot dyno, it definetly feels significantly more urgent & powerful, where often you cannot really feel a small power gain, this one you can definetly feel.

Id say this software upgrade is a winner, and well worth the investment.
Thanx to Simon at QSZ, for giving me good advice, and giving me value for my $$$.
