Straight 6 vs even or oddfire V6.

This is my first post (please bear with me) and I have very little knowledge of how the MegaJolt system is compatible with various engines. I have a source for a Ford ECU/coilpack/sensor from a 1992 Ford Explorer. This is a V6 engine (even fire, I believe) which means there is a piston at TDC in the ignition stroke every 120 degrees. So this should be the same as any straight 6 engine (in my case an old Willys Tornado OHC engine)? I hope to get through AirCare with the help of the FordECU/MegaJolt upgrade.

What about the stranger situation where you might want to use the Ford + MegaJolt ignition on an odd-fire GM V6. These engines, found in some older Jeeps, were actually cut down V8s and had uneven gaps between the firing of the cylinders - hence the name "odd-fire". I guess the Ford ECU + MegaJolt would not work with such an engine?

Thanks for any help learning these fundamentals

if you want to use this odd fire cut down V8 then you should consider using a V8 setup with 2 coil packs and not using 2 of the outputs.

Yep that would work a treat, there is almost a way get around most things

Yes, thanks Dave - using the V8 based system makes perfect sense. I didn't think of that!

Now in my case. the the 92 Explorer V6 based Ford ECU plus MegaJolt will work with my ancient straight six I trust?

Thanks

That's what I've got on my ancient TR6 (EDIS6 & coil pack) and it works a treat.

OK then Dave, I'll go ahead with the Willys project. If it works well, I'll do the same with our Healey 3000.

Thank you again gentlemen!
