Hello everyone, I'm very new to the tuning world and I'm having issues with keeping my car running after it cranks. I can get it to catch and idle for about two seconds before it dies out and I am unable to keep it alive with the throttle. I have tried comparing my cranking, base engine, and idle settings with a couple of other tunes but I have not had any success. I hope its something simple that I am overlooking.
Here is a video of a crank attempt https://youtu.be/zcfLzjrNCcI
The log of that crank attempt https://rusefi.com/online/view.php?log=448
And here is my current tune https://rusefi.com/online/view.php?msq=754
Any help would be greatly appreciated

Re: NA6 Miata Dies After Cranking
Thank you for the good detail! I don't see anything immediately wrong with the tune or log. Are you still running the stock injectors? If so, I assume the car still runs properly on the factory ECU?

Yeah, it's still on stock injectors and it ran fine before I pulled the stock ECU. The only note worthy "mod" I did with the stock ECU was advance the ignition timing to about 14 degrees BTDC.Thank you for the good detail!

Re: NA6 Miata Dies After Cranking
can you try and check ignition timing with a timing light? You may need to adjust the trigger offset if you've moved the CAS (and even if not, the position is not particularly well defined from the factory)

Re: NA6 Miata Dies After Cranking
I meant to come back and post my fix but it has slipped my mind.
My issue ended up being that I did not have my fuel pump correctly jumpered at my AFM connector. I found the correct jumper configuration here under "wiring the peripherals" https://trubokitty.com/#/installation
