Hi Guys

I need a little guidance on the best Mustang ECM to use on my Roadster build.

Basically, here is what I have: -

2013 MK IV Roadster 'No Donor' Basic Kit with some upgrades
2005 3V 4.6L Never Used Modular Engine with OEM wiring Harness
Tremec TR3650 Re-manufactured 5 Sp Transmission
The Factory Five 'Ron Francis' Chassis Wiring Harness
Used 94 Mustang brake and Clutch Pedals
Factory Five Racing Electric Gauge Set

This is only my second ever build and I would not exactly call myself an engineer. I work in Real Estate so this is more of a hobby. The previous build was based on an old Carburetor Ford back in the UK some years ago and therefore I have little knowledge of Mustangs or the respective computers used in the past on this side of the pond.

Simple even if a little more expensive is the order of the day. Therefore, here is my list of questions: -

  • What is the best ECM to purchase?
  • Which Model year?
  • I assume used off Ebay or Craigslist would work but if I do this or go for a new one what should I be looking for?
  • Does the Factory 5 complete kit get supplied with an ECM and if so can I get one?
  • Ford only or will aftermarket work well?
  • Which gas pedal should I use as that is one of the things I have still to purchase?
  • Which sensors will I need to add? Will the ones I have on the stock engine work and will I need others for the tranny?



I am about to move my car to a local pro to install and hook up the brake lines as besides paint, that is one of the items I would prefer a specialist to do, but when it comes back I want to get the engine and tranny fitted so this step is me planning ahead for the next few weeks.

Here are my pics.

Any help would be very much appreciated as I know you guys will help me avoid making the wrong decision.
