Hello,
Thanks to all who spend any time helping, in advance.
I'm getting ready to do a rear end swap to the 3.09 differential, however in the tune file I do not see where the differential can be changed.
Will I need to adjust each and every gear ratio to account for the differential change ? Or do I just need to adjust the shift tables by the % of different in the new rear ratio causing the output shaft to spin faster ?
Sorry, I primarily tune on the GM side and the dodge ecm's seem much different.
Thanks again
