The only choices I got were Haltech Platinum (Sport?) 1000, and uh... Haltech Platinum (Sport?) 1000. Quite expensive, but I enjoy it, having swapped out a Wolf3D.
I always find with ECU's though that you have to work out who tunes what first, since there's no point buying a super awesome computer that nobody can operate. Nobody does anything other than Haltech's in WA afaik, and on my 4agte I made a 100hp gain over my Wolf3D and heaps more response. Cost was roughly $3.5k all done, and an extra $600 to run a set of coilpacks instead of the dizzy.
