I dropped a L03 from a 90' rs in my 92' 1500 with a 7747 in it with a TH400 and currently have a ADTJ in it but after datalogging it seems it runs rich while cruising and lean whenever the MAP gets around 50kpa and just gets worse the higher the map goes. I read the bin from the chip that came out of the car that I got the L03 from and was wondering if it would just be easier to tune what I have now or copy over all of the values on the table from the 8746 bin to the tables for my 7747? I ported the heads and all that simple stuff so I figured I'd learn how to tune it anyways but yea.

And if it would be better to start out by copying the values for the tables from the 8746 bin I figured I need to keep my TCC stuff the same but what else do I not have to copy over? Thanks

 

They are both for the same engine. So the differences shouldn't be that much. Compare the two VE tables between the two cals. If there are large differences then copy the '8746 ones over.

Need to be careful copy SA tables over. As an f-body is lighter and geared differently.

Other then that, I'd just move forward and tune it.

Alright thanks, the VE tables are pretty different but because of the physical difference between vehicles I reckon I'll just tune it from here.

Thanks for the help.
