Thanks Vas........I guess this means that replacing an ebc with the original ebv on a car that has been mapped will not work to well?
Flea my new coupe isn't mapped I have a few spare bits, chips etc from the old coupe and I want to start playing with the new coupe but I haven't got an ebc for it yet, the old coupe ran with an apexi (which I really miss).......so im wondering what will happen if I stick the chip in the new coupe, would the chip in theory control boost and the ebv still cut back boost where necessary? I appreciate it's not safe and even if the chip will control boost the fuelling be out due to it being a different car, even if it has been modded in same way, im just thinking aloud and wondering how a chip from a mapped car with an ebc will react to being paired up with an ebv.
Cheers
John
