Hi guys,
I have a 86 325i e30, that I converted to Speeduino, the car ran for one year now, when suddenly it wont start anymore and does not get any spark, I swap the coil, the cps sensor, the relays and nothing seams to halp. I quickly went over tha wiring, nothing seams out of the ordinary. Now I started to check the speeduino, and noticed that the LEDs for the Ignition drivers don't come on when I'm cranking the car, I assume that the the ignition drivers would be at fault, is there any way to say for sure.
If anybody knows anything about this please let me know. Thanks

Can you share a data log of it cranking?
