thinking about switching to jdm 2jz ecu, any input would be great

You can't raise the rev limit with piggyback systems. Also G-Force isn't the only option. You can get aftermarket ecu's made for the aristo (such as Blitz) that wouldn't require you to get a piggyback that eliminates MAF. I honestly don't know if there is a Gforce made for the aristo but like I said its not the only option.

i thought you were able to change the rev limit with the emanage ultimate? y can you not change it with the emanage ultimate?

The 6800rpm rev limit really bugs me with a larger single turbo, and even more so when I think of the headwork in the cars future. It's a given that I will be getting rid of my current 2J ecu just because of the rev limit alone, if nothing else. I have no idea as of now what I will replace it with though.

The car really does drive perfectly off boost though. It really drives well. I'm sure I will miss the current "around town" nature of the car when I change it.

which 2jz ecu did you use? aristo or usdm supra?

Will running a 2J ecu on a 1J allow me to run the 440cc 2J injectors without a piggyback like an safc?

You could, but that doesn't mean that you should. You should always tune your setup.

 

[86_sports_1jz]

yes like he said^^ but it will run better on a tune... you can run 440s on a 1jz ecu but need to tune

Itll still be rich, as its tuned for a 3.0L engine vs the 2.5 you'll be using. But you could get away with it for a while if you had to.
