I have a 84 Z28 that I converted to MAF TPI. I'm using Painless wiring 60102 for early TPI and a 1227165 ECM. I have 24lb injectors, and a holley AFPR. My engine is a GM Goodwrench 350 with a comp 12-314-4 cam for Stock 350 TPI. I can get you the specs if you need. The top is Dart Iron Eagle 64cc heads with 180cc intake runners. Flowtech shortys and Y-pipe into a 3 in Flowmaster cat back. I'm using a Borg warner M39 5-speed manual and was wondering which Bin file I should start with. I bought a hypertech 127062 chip for a 1987 350, but it only came with auto tranny and wasn't really optimum for my injectors. I was hoping to change to $6E and eliminate the cold start injector. I have a copy of the AUJN.bin and the APYP.bin, but they have very different timing schemes and was wondering if there was a better place to start with that setup.

 

APYP is for a Corvette, aluminum heads and a ZF.

AUJN is for a Camaro and may be the best place to start. At least for the timing tables.

Can copy over the IAC stuff from APYP and un-check the TCC bit first.

Which is the TCC bit??
