nope i would actually stick with this ecu if its in good nick. there is now three hks dealers in Qld that are authorised to tune these.. GT Auto garage on the northside, Gavin Wood Autotech down the coast and of course Advanced Performance Centre who i'd highly recommend. no other workshops have access or the training for this software despite mercury telling my friend that they can tune her supra with an f con and all they did was run it up on the dyno lol
