Hello

We have LS1 in kit car in this configuration:

- custom wiring, whats not listed, is not present
- Mechanical throttle body with GM 3 wire TPS (working ok, according to EFILIVE software) - no TAC module
- Stock 1 bar MAP sensor - working ok
- no MAF (maf table zeroed out)
- intake air temp sensor - working ok
- no body control module, Vehicle anti theft control set to NONE
- no lambda (disabled)
- no errors

We tried to copy map from our other LS1 equipped kit car , which is running perfectly and no help. Other car has MAF...

We suspect problem is with VATS, but there shouldnt be when its set to NONE...

When trying all different settings, we were able to get PCM into UNSECURED status and then engine was running. Now is PCM back in NOT LOCKED status... and starts and dies...

Thanks for any suggestions...
