I have a MK5 jetta cjaa dsg 2010 it's stage 3 with xman cr170 and cp3. I'm looking at a golf mk6 cjaa dsg. The ecm/ecu my jetta is using have the immo off or deleted by Malone. Could i use that ecu in the mk6? it's cjaa and dsg but it has kessy, the keyless entry and start system thing. So idk if i would have to buy a new tune for the mk6 if i buy it. Does anyone knows? Thx.
