7a-fe megasquirt questions Options

[238ur50]

Ok, Here is the deal.
My buddy has a 93 Geo Prizm and he has the 7a-fe in it which i tracked it down and see that the 6g celica does too, ok now to the good stuff


I see alot of you celica guys recommend the MegaSquirt Which I love, I have it on my Neon and Mustang

and we bought it and would like to use it on my buddies car, however i have not seen any use the stock dizzy with the 7a-fe and megasquirt, i know i could just get the EDIS-Ford stuff but we would like to use the stock dizzy and such

i also see the alot of 4a-fe and 4age guys have used the megasquirt how much different is the engine wiring and pcm for the 7a-fe motors from the 4a-** motors and can i use and install document for a 4a-** motor on a 7a-fe motor?


thanks

The wiring is pretty different.

You can probably use the stock distributor as a crank position sensor and one of the stock sensors(I've seen Ne used on a AE101 4A-GE) and run the MSnS-extra firmware. I'm not too familiar with the 7A-FE distributor setup though.
