Seriously though. Any computer can work.if tuned correctly. The same as any computer tuned badly will kill your engine.

So complete answer is " f**k knows ".

Looks OK sex specs wise....the real trick is finding somebody that can tune it.  Many can try, but only a few will get there!

This is just spec table comparisons but I personally value MAF support a lot, if only to not have to sit down and spend time dialing in a VE table. ProEFI doesn't support the dual MAF config on the RB26 and I don't think they really support anything other than the RB26 at the moment. The vast majority of tuners don't seem to use MAF tuning but I have weird obsessions which seems to end with me DIYing this stuff as far as I can tell.

I agree, I've done it before and it's not that bad but in the case of the RB26 the ITBs add extra "fun" that I really just can't be bothered to deal with. I just fundamentally disagree with using alpha-N as a load sensing strategy to compensate for where speed density doesn't work in ITBs.

From some chat my a buddy said these computers the toyota supra guys usully use them on a 2jz. My car is wired up with stock ecu and this ecu they didnt want to touch stock ecu, so i have a full proefi128 harness made by wiring specialists for the stock ecu and for computer. My goal to see if haltech works with the sensorsand ebcs

If you want to run a Haltech there's no harness needed, you can just run the stock harness and sensors/actuators. I believe it is recommended somewhere here to swap the stock boost solenoid and go from a 2 port to a 3 port solenoid with vacuum lines to suit but I haven't gotten to that part yet.
