Hay guys

Got boared and wanted to see wat my car would run on my old 3.5 TH standard ecu car ran fine sounded normal i kinda booted it in 1st and 2nd gear seemed to go well also. I've heard it's ok to use the 3.5 ecu in the 3.8 but I heard not too use it also.? Put my tuned ecu back in after short drive off the 3.5.

Cheers kurt

6g74 runs 5-10 degrees btdc, so there should be no issues on a 6g75, however, a 6g72 runs 15 degrees btdc so there could be det issues there.

I run lots of 3.8 with 3.5 ecu

Brendons kf has the kf ecu, gets driven hard and has been running over a year now

I assumed u had to make changes for the 3.8 engine to the tune. Is there any difference or gain?
