3.5 efi Flapper to Megasquirt conversion

Recommended Posts

Using "fixed map" sorted the first start of the day issue for me. I ended up with similar settings:

Use fixed below 30deg

Time period 8secs

Fixed map value 50kpa

Can start through the window from cold any time. Its a 3.9serp with ms1 and edis

Oh, and yes, I forget more than I remember these days, a fixed MAP for ASE can help loads... just simplifies things.

so it seems to be working now at those last settings I screen shotted (screenshat?) ...... hasn't strangled itself now for 3 days on first start...... but..... it has been 1-2 degrees warmer, so difficult to say, but I think we have found the solution.

busy planning my first service since installing MS, with the coil ignition do i still use the same spark plug? or is there a better plug for more spark/better ignition? engine is a 3.5 with 9.35:1 compression

Yup, standard ones are fine, NGK preferred by many for the RV8 :)

and spark gap, digging through the forum I found a value of 1mm because of the ford coil packs? 

the standard gap was 0,7/0,8mm?

I doubt very much it will make much difference to be honest, it's not a race car or turbo's, it's a 1950s engine with poor combustion chamber design :)

EDIS probably won't worry too much about spark gap...

perfect then I'll just leave the new ones lying on the fender and hook them up and it should work :rofl:

I found EDIS better with a 1mm gap - subjectively anyway. Logically, if EDIS will drive a spark across a bigger gap (which it will, comfortably) then you're better off with that bigger spark.

In any case, 1mm is what Ford specify for EDIS equipped engines.

I'll be setting them to 2mm and be going a whole lot faster :ph34r:

jokes aside, thanks for the feedback guys.
