Shift point adjustment...going from 26's to 28's need help...
 

or advice:D I am going from 26x11.5x15 ET streets to a 28x10x15 ET drag. I know I will have to correct the tire size in ls1edit to the height of the 28. But will I have to correct my shift RPM and MPH and by how much? I need this advice PDQ as I will be racing it tomorrow night.

Thanks,
J:D

going to copy to Drag Racing tech and see if you can get some help in their too with this one ;)

Thanks:D:D:D:D

If you had HPTuners you could adjust it in the Speedometer dialogue and it would rescale your shift points automaticall. LS1Edit supports rescaling too. Enter in the new tyre size and it will optionally rescale your shift tables. Too easy.

Cool MNR-0 Really didn't know that about edit:emb: I still getting use to it.
Thanks:cheers:
