Well, look's like the microtech's suck for RB engines.
then again, im no RB expert, but judging from std ecu's there only good on the standard engine/turbo.
but why go aftermarket ? just get a proper ecu.. a power FC is good for the line's..
there good and they have a base map, cant you fork out 1,000$ and get one ?
it will save you in the long run
