Ive a focus rs engine that i want to fit in a mondeo. Why does nobody fit the focus rs loom and ecu? what complications are their?
Talking £2000 to fit link management and rolling road set it up and still told their will still be teething problems and various returns from the tuner.

I havent that sort of money to throw away, thought if i could set it up as focus rs was then no rolling road or teething problems or less anyway.
Whats needed Ecu, engine loom, key, sensor for key at steering lock, heard somebody say it needs dash/clocks.
Anything else?
