Replacing speed set

[efrickle]

I've heard of that system, just didn't know that was what MP was exposing on that engine. Given that it's analog running in the long harness from the console to the ECU, I'm not surprised it has "issues"... lots of opportunity for noise pickup in a setup like that. Better if it were a differential signal, but that may have been more complexity than they wanted to deal with back then.

Funny thing is, I specifically remember a discussion I had with Perfect Pass a while back where they described how they talked to this exact type of system. I can't remember, but have you called and talked directly to PP about your engine? Are you certain THEY say it's not possible?

I have been on the phone with Perfect Pass and Zero Off and neither company has anything that will work....so they say. I would assume that someone has tried it or those companies tested this year of MP ECM and came to this conclusion. When I was talking with Marine Power, he was surprised that I wanted Perfect Pass over the Speed Set. According to them the "Speed Set is superior"....hmmm, not sure how they figure.
