Hi guys,
I'm putting the 2jz into my car shortly and wanted to clarify a few things. For starters I've heard you can run your soarer via the 2jz ecu but will this also apply to running the soarer transmission? I also heard something about a full body loom or something like that whereby you use the 2jz ecu to control the engine and the 1jz ecu to run the transmission and inside the cabin etc.
Not sure what is what at the moment but if anyone can point me into the right direction that would be great.

Doesn't really phase me, I just thought keeping the 2jz ecu would be better than using the 1jz ecu as it's setup for fueling etc. I want to use the 2jz ecu to control the transmission and the soarer, just wanna know if that's possible?

hi Austen. Most auto electricians won't attempt what you have done, because there are grey areas such as 'split signals" etc. You wouldn't be able to draw a basic wire diagram would you?

i thought that the 1jz ECU will run the 2jz, just have to run turbo's in parallel, fuelling wise, since the 1jz ECU over fuels a 1jz when running 2jz injectors... wouldn't it run the 2jz just fine?
running the turbo's in parallel is a bit of a job in itself. unless you can get a hold of two 2jz front turbo's and spin the housing on one to bolt up to the rear, then have a custom dump fabricated.

Sounds good keen to see the verdict, looking online it seems this is quite common with the sc 300's in America and even with an auto transmission not just the manuals. Might be worth running an emanage off it I would think.

The Supra TT auto has electronically-controlled line pressure, the Soarer TT auto has cable-controlled line pressure, so the Supra TT ECU needs a Supra TT 'box.
Someone on the UK Supra forum built a hybrid, by swapping the cable-controlled Supra N/A valve body on to the Supra TT gearbox, so that he could use the stronger TT gearbox and the Supra N/A ECU with his supercharged 2JZ-GE (also a good solution for a tweaked 1JZ-GTE auto?). It should be possible to do the opposite - Supra TT valve body and Soarer TT gearbox.
On the other hand, Supra TT autoboxes are pretty cheap (well, they are in the UK), so you could just transplant the whole thing. May need a custom propshaft?
I would think if you want to use a 2jz-gte + 2j ECU and run your 1jz-gte Box, it is simple you simply wire in the solenoids, and make sure your Line pressure cable is adjusted and it should work but so long as you can somehow modify the 2j throttle to fit the line pressure cable and make sure the length etc and load on cable is good when the throttle is applied.
Do not use a 1jz-gte ECU to Control a 2jz-gte Motor, Sure a 1jz-gte DOES run rich on higher boost levels but how do you know what it is doing at every single Load/Rev and Pressure point to be able to be confident that it wont run lean if you put a 2jz-gte in there. If you want to go down that route get some sort of aftermarket ECU.
I would say the easiest way is not to do any sort of Hybrid stuff because in the end it might sound easy explaining it, but there is always those little issues that pop up. To avoid the trouble Use a 2jz-gte Motor with a 2jz-gte Automatic Box with a 2jz-gte ECU, anyway 2jz-gte Automatic is stronger.

2jz non vvti i dont see why you cant use the 1jzgte box, 1jzgte throttle body and cable, 2jzgte ECU and a suprastick auto box controller. (button shift!)
arent vvti engines fly by wire throttle controlled?
