I've noticed during launches with "pwr on" that the ecu shift points are around 5K rpms. Should I be targeting this same rpm range when I manually upshift? Where do you want to keep the rpms in order to maximize within the power band?


Thanks,

Optimum shift point is where the power curve of the lower gear intersects the power curve of the next higher gear.

If I had the power curve and the transmission ratios, I could calculate shift points.

Does anyone have: A) Power Curve, B) Transmission ratios?

Not sure what you're looking to accomplish but all the reviews I've read said that best acceleration times occurred by putting the trans in D and letting it upshift automatically.

yap... that was what I heard too.... I forgot where I read that article... but I remembered that they said to get the best performance is by putting in power mode with vehicle skid control on....
