So So Sorry to bother you folks but I'm desperate.

I'm in the middle of building an Exocet with a LFX. The engine came from a 2014 Camaro and had the E39A. I was told that I need an E39, so, I bought one on Ebay and that came from a 2010 Cadillac.

The wiring harness came from V8Roadsters where they eliminated anything I didn't need and I have it and the engine installed.

It starts for ~2 seconds and dies. I have fuel to the rail from a 58psi regulator. But, the ECU is reporting fuel failure. I pasted the log below.

Also, I have a tune from a person that has the same setup. I was told not to flash my ECU with his tune because the OS's are different. Is this true, or can I just write is tune complete onto my ECU??

V8Roadsters is telling me that I have the wrong OS but I'm afraid they're getting tired of me and are not providing much help now. I really can't blame them. I've been a PIA.

I don't know what to do.
- can I flash the complete tune from this other person? (different OS)
- if not can I make this one work, or do I need another ECU?
- and if I do need another ECU then which one - which OS?

Thanks
Frank
