I know there are several topics on this and I have helped a guy that chased his rfi problems for a few years. My question is how far from ignition source do the controller wires need to be and do only the micro switch wire to the controller and the grounds for the solnoids need to be away from the ignition source. I am having a problem with my car where I don't think it's running like it should it's about .100 off and about 3-4 mph off. I have tried several converter in the car and it does the same thing on every one. The one in my car now is out of a car with a engine just like mine cars have same gears and pretty much same engine but the converter won't act the same in my car. Any input will help. My controller wires are about 5-6 from coil and 3-4 from the distributor. Always shows to be at 100% at the end of the run.
