It finally all worked out, I was able to get it to read everything. I did get an error code 34 (which is the knock sensor/detonation) message. I.E. Mine isn't hooked up.
Now I looked up on TT.net and read that they dropped in a 1 Megaohm Resistor to "trick" the ECU. Will this work on the 2 knock sensors on the RB25DET?
Well... give it to Top Secret for putting every engine known to man into a MKIV Supra.
They've done RB26 Supras, and many more, some 4 Cylinders (3S-GTE), obviously 2JZ's, and now this?

You're going to want to stay away from the internal gates at 400+ WHP.
The largest turbo I would go with an internal gate may be a GT3071R but the GT3076R's and up I would suggest external.
Flywheel and starter shouldn't matter as to pull or push type from what I understand. Now I'm not sure if your RB26 starter bolts to the RB25, that's a question I can't answer.
But as for the flywheel, push or pull type clutches bolt onto the same factory stock flywheel. The flywheels can be different if you have aftermarket pull/push multiple plates.
If I am wrong please correct me anyone.
I seem to be having a problem... I can't get the damn thing to work with this wiring... I wonder if the RX is completely wrong...
And also.. does the CHK have to be plugged in? Or just the 4 and the IGN?
I would jump down to a GT3076R and detune it a bit for response in the 450-500WHP range. Still spools like no other since it's duel BB, and it'll still have mounds of power.

Hey I just noticed...Z32 MAF on stock RB25 ECU might have some issues unless you're running a SAFC from Apex. Fire it up with stock MAF if you have it around, it'll work wonders to get the initial start.
