I might be able to, i know AVO can tune them, so maybe give em a ring and find out how much they want to tune it on their dyno, cos they'll tune it with the more accurate wideband oxygen sensor.
They want about $900 for the SMT6 and another $50 for the cable to connect it to a laptop, but Powerchip in South melbourne can do them for $590 with everything, even the cable. You might be able to get them down a bit more too on that price.
I'll let you know whether i can do it or not ok? Either way it's an excellent computer, i reckon a 1000 times better than a Unichip.
