Radio Interference with RR ECM...

[DuramaxPowered]

I have had a problem with radio interference since I installed my RR ECM. Anyone else have this problem?

What sort of interference?
Does it happen all the time?
I'd recheck the ECM connectors are in nice and tight (not too tight), sounds like a ground might be missing.

Could try spiral wound spark plug wires, like MSD Superconductor; they produce pretty much zero EM emissions.

Sorry, I should have said the vehicle is an LB7 Duramax.

lol... I suspected that, but I went ahead anyway...

What sort of interference? Radio stations that used to come in clearly are don't have clear reception anymore. I have put my stock ECM back in and the radio is fine with it in, the problem only happens with the RR installed.

Does it happen all the time? Yes, if using RR ECM.

Everything is properly connected.

Hopefully we can figure this out........

I have had issues with my radio reception recently as well. Seems worst around 92 FM. But I think it is there across the band. Never related it to the RR though. Haven't tried putting the stock PCM back in yet.

I also have issues with radio reception when using my RR also. I can put my factory PCM in and my radio reception is much better. I noticed that when I shut the car off once everything drops out except the radio keeps playing as long as the door isn't opened the reception gets much better. I do have MSD plug wires.

I am thinking that it is not an ignition problem since I have the problem on my Duramax Diesel. I'm going to call Craig Moates and ask him if he knows what to do to fix the problem.
