Thread: got ran by a 2002ish bmw m3

I'm surprised with just those mods you kept him behind you. Those m3's aren't slow.

i was messing around with him on the highway and he finaly got the hint that i wanted to play. he got up behind me at about 90 and i laid into it . he was stuck to my bumper like glue. the lane next to us was open but he never attempted to come around me till i went into forth gear (125) and by 130 he was pulling up beside me and then we shut it down due to traffic. he deffently had me covered but i was suprised i held him off for so long.

hopefully when i get my headers on, 3.4 pulley and a tune ill be the one walking around him . what do you guys think??

Since you have a stock PCM, you should have been cut off by the speed limiter and you should have shifted into 4th well before 125. See if I can find that comg G stock bin, to make sure I'm not dreaming. You must have an aftermarket PCM.

A stock GTP with 2.93 gears has 3>4 shift at 124 and a speed limiter of 127. Since a Comp G has 3.29 gearing I would assume the 3>4 shift would be set a little lower but the limiter the same. Looks like you were pushing it to limit and maybe beyond.

Thought you might find this interesting. Again, this is a GTP so the MPH shift points are likely higher than a Comp G.

Because of the drive-by-wire system there are the equivalent of 2 throttle position sensors. A safety feature, incase one of the sensors fail. The PCM looks at both sensors and if they arent reading within a certain tolerance of each other, then action is taken to prevent a possibily dangerous situation.

Yes the Comp G (GTP) has 3.29 and the standard GTP 2.93. This is why I said the WOT shift MPH would likely be lower on the Comp G. At the same MPH in the same gear the Comp would be at a higher RPM (200) than it's brother.

and my car is the gtp. i thought all comp g's were gtp's?? sorry i dont know that much about the comp g's.

You are correct, I wasn't clear.
