anyone have any really noticable tuning tips for the mg zr ??
yes our class is limited to tuning not allowed any internal add ons, is there a chip that uses the standard ecu ????
I think we may have a few new standard motorsport ecu's in all the spares we got when mg rover closedDastek used to do a piggy back chip
but ZandF tunning can remap the standard mems ecu these guys worked on them at Rover and are easily the most knowledgable people with mems 3
