Ecumaster forum

when I am not connected to the EMU i have all the features fuel trims adjustments ignition lock some others but mostly focused on those main ones. but when i connect to the emu those are gone. why would it be doing that.

have you updated the firmware on the ecu ??

yes that was exactly the issue for that. now im having issues where it will start for a second then die or if it idles for a couple seconds then it just dies like its not getting enough of something.

Was the car tuned before the upgrade?

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.

sound like you have no live after start

Wherr would I go for live afterstart? Is there something specific I should look for?

Post here your base map and log file when you try to start the engine

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.
