I would personally go with cossy management if i wasn't going to set the car up my self. agreed its by no means new but ford would have spent 10 maybe 100 times what emerald did in development and testing. You will nearly never beat an oem ecu for drivability plus there are countless tuners who can easily map the weber gear. Have a chat with MSD about their wated spark, closed loop and launch control boards.

If you were mapping it your self i would suggest nothing other than megasquirt.

Im not slating emerald, omex, pectel etc. Just making an observation over development of the systems.
