NIStune works much the same as JWT from a Calum approach. you send in your ECU to them, and they attach a daughterboard. they also attach a port allowing you to hook up a laptop to tune it, and the programs are available from them.Well, it would be good if the ECU's are new. since our 1992's are older now, JWT tunes them, but not sure if they fix them if something goes bad. I thought of buying a few older ones to keep on hand in case mine goes bad. But, if Nis-tune is doing packages, does this mean they are new units, and are they tunable with a laptop through the ODB1 port???
Keep us informed. its too late for me, JWt got my business. they do an excllent job on theirs. Price is Key!!!!

probably, provided N15 GA's are no different from b14 GA's. just, you can't get N15's in the states, so some of the mapping might be different.just out of pure curiosity, since i dont know much about ga16 ecus..could a ga ecu out of the n15 work with the b13? again i dont know much lol
