Stock ECM tune says 3.73
Stock TCM tune says 4.10
Both are called H0103. Is this normal and why?

: ECM and TCM not showing same final drive ratio bballer182 03-29-2008, 01:31 PM It's my understanding that all tcm say 4.10 as final ratio. I just made sure that the revs per mile match in the ecm and tcm. EFI Support 03-29-2008, 05:45 PM It's normal.
