We only use donor Mustang drive trains. We have built 2 thus far, one Mk IV and one coupe. We use the Mustang transmission and diff. A couple of things that are required to do this: the Mustang shifter is about a foot too far aft. To address this we developed a top loading shift mechanism that bolts to the top of the tranny. It also requires building a non traditional drive shaft as it bolts to flanges on both ends. As for using the Mustang ECU, we have never tried. We modify the engine harness and use and aftermarket ECU and a coil driver that we developed internally. You certainly can use the Ford Performance ECU. The advantage of the ECU that we use is that we get traction control, lunch control, flat foot shifting, and variable drive modes (i.e. track or performance vs. cruise mode) and of course flex fuel. These features are not available with the Ford Performance ECU.

We are about a month away from being able to offer the shift mechanism and drive shaft for sale. For your reference, our shifter includes the following:

• FormaCars Billet top mount shifter assy
• FormaCars Billet reverse lockout collar
• FormaCars Mark IV or coupe rear transmission mount
• FormaCars Mark IV or coupe tunnel sheet metal for MT82
• FormaCars Shift boot for MT82
• FormaCars Billet shift boot trim for MT82

You’ll need from your donor transmission:
• Shifter lever
• While reverse lockout sleeve, spring & screw
• Shift knob (or aftermarket Mustang shift knob)

As for the ECU we can probably help you with integrating our solution if you are interested.

hope this is a little helpful
