Try to load the last know configuration.
From what firmware version (and to what version) did you upgrade ?
What engine ?

Sorry it's a 2jz na-t setup on 7m electronics 7m cps and coilpacks. FFIM 880cc injectors precision 6776 turbo 255 fuel pump. No this is on a 7mgte basemap. First startup After converting to EMU. thinking it might need a 12v mod relay done to the car its a 89 toyota supra.
If i hold the key to start for a few seconds when it starts it revs up a little higher and runs longer till I let go of the key and then it immediately dies.

Sounds like the fuel pump isn't turning on. The stock wiring powers the fuel pump whenever the starter is engaged. You can always jumper power to the fuel pump for testing by connecting a wire between the +B and FP terminals on the diagnostic block connector on your engine harness. If it runs with that jumpered, you need to look at your fuel pump output settings and possibly rewire it, as you said.
