1989 1 ton chevy 454-th400 truck. 90,000 miles

Current setup on ecu is Moates 24>28 pin, G2x tbi switching adapter, zif, 27sf512 chip, apu1, tuner pro:

just got all up and running yesterday. did a short datalog. using (AKUN 89 truck 7.4tbi 3 speed auto.bin)
($42-1227747-V4T.xdf) and ($42-1227747-V3T.adx)

Question is: IAC desired idle is at 750 rpm on all cels (idle in tuner-pro shows rpm at 1000-1200) when i try and change idle rpm there is no change. When I shut down the motor and restart check engine light is on and IAC is wide open. I have to change all the cels back to 750 and restart motor (sometimes 2 or 3 times) to get idle back and happy light again.

looking foreward to figuring out tuner pro and them bin files!
