I think it's $260 for the ODB2 board and $240 for the ODB1 ($AUD), Software to tune it yourself is $200 or take it to a dealer and pay them to tune it on the dyno. I haven't checked what the dollar is doing vs the AUD but it's prob getting it's ass kicked lol. No real down time if u take it to someone who knows how to electronic work like a TV/VCR repair shop. They have the other one Nismotronic but the Boards aren't out for it yet so no price on it. Could be cheaper or more. I think they only do ODB1.
