Solid CEL and IACV humming
Hi there,
I have a a chipped JDM P30 set up with Moates Demon 1. Problem is I get a solid CEL and the IACV making a buzzing noise when J1 is jumped. I can upload and verify maps to the Demon fine. Fuel pump primes. When I cut J1 there is no CEL so that rules out the ECU being faulty.
What do you guys think is?
Here's a video

Thanks

Re: Solid CEL and IACV humming
it's probably just a corrupted rom. start over with a new rom. if that doesn't fix it, make sure the demon battery isn't bad, make sure the headers are seated correctly, then try the demon in a different ecu to see if it follows the demon or stays with the ecu.

most people don't tend to notice that unless their fuel pump isn't priming. however, if your rom or ECU is bad the IACV will pulse at a different rate causing a lower hum, which can be louder.
