FiTech EFI system

Sorry to hear you are still having interference. I have only shield my wires so far, I never had any issues with that as far as I can tell. I did buy the stainless wire, and ground the unit well. I did see numbers moving at and heard/hear clicking KOEO though.

Some updates, I found my damper had slipped. This meant when I pulled and locked the distributor and re-timed it timing was off. I also relashed my valves. I found that even though I had saved my engine as a 340 cubic inch and selected the #3 cam (twice since it didnt take the first time) the fitech showed it as the base setting 400ci with a #2 cam.

Should I start a relearn or will it adjust?

On the issue of key on engine off random numbers, I think you will find that it is the o2 sensor wires, when the o2 heater is active prior to starting. In the most recent software they sent me for Go efi 4 power adder version, it has a setting to turn the pre heat off, and that got rid of those Key on engine off random tach numbers.

It should save your main settings, even with the battery disconnected.
