I know how to calibrate the speedo, but will I need to change my shift points if I change gears?

If I do by how much? Is it safe to do the following for the appropriate shift tables (because they seem to by Throttle % & MPH for the shift points)

3.73 / 3.23 = 1.155

Increase all shift points to approximatly 15% more than what they are right now?

 

If the car shifts based on mph & throttle % I don't see why you'd change the shift tables if you've already changed the speedometer calibration.

I'm no expert though, you might want to post this in the computer/programming section, you'll get a more technical response there.

 

Good Point, I'll do that now. Right now (looking at the tables a bit more) it looks like if the car shifts at XX mph now, id want it to shift a bit sooner with new gears since the rpm will be running 15% quicker. Basically the car @ XX mph will be at a much higher rpm if i don't. Thnx for the input though... Hopefully the comp guys will clear things up a bit

 

Oh ok.. sorry for the confusion. I thought you were saying make the mph 15% higher Now that I understand your way seems like it would be fairly accurate.

 

yea got my jumbers all numbled up Copied the post into the computer forums so hopefully someone sheds some light on this. I'm pretty sure now i'll have to adjust shifts too by the looks of it
