Interesting Info For EFI Guys Experiencing EMI/RFI Issues

I'm running old(er) Mopar solid core (steel stranded wires) sparkplug cables with my MegaSquirt 3X.
Leanburn distributor, 7-pin HEI and MSD Blaster SS e-core coil.
Turn on the AM-radio in my '73 Dart and you'll think it's a Geigercounter.

Noise filtering is 'on' to filter out any possible trigger signals that shouldn't happen but the engine revs to 4750 easily without missing a beat.

Not quite sure anymore but I do recall to have suspression sparkplugs.
The Iridium type.
