Fel Pro ECM

[Tyson McPherson]

The way I understand it Holley's four injectors are high impedence, so the
four drivers in the ECU can handle eight low impedence injectors (two per
driver). I spoke with a coulpe of the engineers at Holley about this, and
they have also used the 4DI computer on a 1989 or 1990 Ford GT Mustang. It
was done just to do it, and no further testing, that I know of, has been
done by Holley.

Still gathering parts for the Mustang, but getting close. It is a 1968
Fastback, the motor is a stroked 351w (now about 383cid) with a roller cam.
We estimate about 400hp. Plans are to fire the engine on a dyno with a
carburetor, and then switch over to the muiltiport 8DI system we put
together.
