85 Y Body TPI 1226870 ECU Tunerpro Help

Hi everyone im seeking help in burning a chip for my customers 85 Corvette TPI. 870 ECU.

99% of the time I don't get any data logging via ALDL cable.

I am using flash and burn to burn to SST512 chip.

I have made changes to the $1f bin via Tunerpro but every time I burn the chip the check engine light is on. If I stab the gas pedal the car acts if there is no fuel but slow rev it will rev hesitantly. I've put in the deadtimes for 24lb injectors and tried scaling the MAF in both directions + & - and same result.

Can anyone who has experience with tunerpro help me out please

Offsets? <click What are you using to connect to the aldl?

Absolutely was chip offsets. I downloaded someone else’s stock $1f file and saved and tried to burn and the Chip offset was correct and worked. I was able to start tuning the car today. You telepathically helped :rockon:
