Re: [DML] Serious Megasquirt Question

["Owen" <omalbec@xxxxxxxxxxx>]

What is your contingency plan today should your stock Ignition Control Unit craps out (it is 30+ years old after all)?  Or your stock RPM relay? Or your fuel pump? Or.... we can play this game all night. It doesn't matter one iota if your fuel delivery is mechanical if your spark control is electronic.

I for one believe that whether one is K-Jetted, carburetted or EFI'd, AAA or classic insurance with towing package is probably a prudent investment.  I don't care what your fueling mechanism, if you lose your spark control, you're screwed.
