Torque Management IN ACTION!
For some reason I couldn't get the link to this to post and direct you correctly so I'll just repost it here. I found this:
This snippet is about 700 frames, or approx. 7 seconds.
Starting from left, with about 2% to 100% throttle (floored!), you can see the transmission downshift into first, as RPM and VSS start to climb. Then as PCM calls for tranny to upshift into second, note the spark advance - it goes from the +25 range to -5 for a FRACTION of a second as the tranny shifts, as indicated by the RPM drop. Also note the (insignificant) 0.4 of KR.
Those who think TM is a major ET limiter or HP killer, can see why it'* not that big of a factor, and why leaving it alone, if modifying your PCM program, is a good idea for the life of the car.
Now if you have substantially modified the drivetrain.....

Ok me again. You can see what is being talked about, its the sharp dip you notice. Its really very short. Interesting to actually see it happen.

I ran the car w/o the traction control the other day in slippery road conditions, I didnt like it. Too much unnecessary load on the tranny. Keep it unless you are gonna race on ideal road conditions. We keep ours on all the time on the '97 and still have the original tranny. The most we have done is a fluid flush I think.
