I have a NOVEMBER 2002 mini cooper s and have currently got a MTH tuner file on the ECU. Due to a engine faliure i have had to get a replacment engine and basicaly have pretty much the same mods as a jcw.setup.A friend is getting my ECU remapped with a JCW map.My question is as i have an early ECU will i need some other upgrade before the JCW map can be loaded as in MC SQUARED MAGAZINE it mentions something about it in an article where a guy is getting a works kit fitted.
