Hi guys and gals. I’m finally in the starting/tuning stage on my big block chevy MPI setup with a 0.4.3c board, fuel only. I have found a bad MOSFET for INJ3 that is stuck on constantly. The other 3 outputs are working fine. I am just curious how common is this to happen? I have checked my harness to verify nothing is shorted.
This seems like a bit of a big deal as this one failed on and was dumping fuel constantly when the Speeduino was powered up. Just looking for thoughts on previous experience. Thank you in advance!
