I have an 85 corvette with a 1227730 ecu in it and a $1F Mask I.D. is it possible to keep the 1227730 ecu and upgrade to a $8D Mask I.D? the 8d has allot more support and seems to be a better all around tune. I figure I would have to get a moates G2 adapter for a larger chip but is that all I need to do. is this even possible?
