you put a resistor where a diode should go. the idle valve flyback protection...
you need to remove r39.
you need U5 installed.
You have your INJ outputs going to both your injectors AND coils.
What directions are you following, because youre not being as meticulously as you think.

1995 Miata M edition home, brew sr20 t25 turbo setup. I built a diypnp, 76 pin ecu, meticulously went over the board and loaded firmware off diys website. I put all the jumpers and what not in according to the instructions, and I cannot get an rpm for the life of me. The car ran fine, just lean, with the stock ecu. I don't know what I did wrong, but loaded a start up map off their site and double checked the ignition settings, then burnt the first coils out, and just burnt the second ones... like smoke coming off of them. I'm pulling my hair out, I thought this would be fun. I was wrong, should have had someone else built it. Any info would be greatly appreciated.
