P0335/rpm noise
#1 · May 4, 2019, 5:27 pm
Has anyone found a real remedy for this? I’m not using timing control, blue wire is tapped into my tach wire in my 6al box, I’ve wrapped and insulated the wire... suggestions appreciated..

Can be other things. Not just the blue wire. Bad grounds. Coil or plug wires too close to ecu. Fitech wires laying on plug wires. Blue wire loomed with hot wires. Etc.
Also try rounding the shielding.
Many people solve this issue, but is install specific on each one. Send some pics of engine bay.
