I hope this makes sense lol

can you get rid of or bypass the immobiliser system so that you can use the standard loom and ecu from the focus rs in something like a mk2 fiesta along with the rs lump, as if you could id rather do that than spend 1600+ on something like omex

 

i couldnt find anone who knew how to bypass the internal pats system in a mk6 rs2000 ecu so id be quite surprised if you can do it with a much newer car like the focus im afriad mate. but you never know, someone may know how!
cant see why you rcouldnt use a basic system like magasquirt and just have the standard rs focus map loaded onto it though, wouldnt cost you even half 1600 id imagine?

 

You can get up and running with a 3d aftermarket system for well under Ł1K, a triple map system, that only costs Ł275 for complete mapping as well, all three maps.
It alos has some(lots) unique features and does CL with EGT.
