a good tbi ecm should be way easier, and probably be WAY better in the end, ditching the maf and just working a good speed density tune out

alternatively a standalone transmission controller should work well

if all you want is overdrive, though, why not just get a 700R4?
Steveo, I'm going to run my 4l60e and tpi off an TBI ecu. I saw a bin file for this very swap a few months ago and now I can't find it. Any searches came up empty cause I can't recall the title. Does anyone have a link to the thread and or the bin file. Thanks.
