RF Interference with EFI System

[Fuelie Fan]

How do you know that this is your problem? Do you know that it is RF (through the air) or EMI (through the wires)?

As a note, as mentioned above crack pickup should always be wired using shielded cable.

Hey Guys, I really appreciate the info.

This was brought to my attention by the engine builder, Tom Nelson.
He said that they were having all kinds of intermittent problems and when they figured out what it was (electric water pump to EFI interference) they ran the water pump from a separate battery, i.e. a separate hardwired electrical circuit and the problem disappeared.

So in answer to your question, it must really be EMI, not RF.
I guess that means when I go out for the dyno test, I will need to bring gobs of sheilding material to see what works.
