Tt ecu on obd2 car
Hahaha nice, anyway I have seen some top fed fuel rails for a 1jz that might be a good thing to pick up and not have to deal with the resistor box I'm looking for a fun clean turbo swap not looking to go crazy numbers so if you can get to close to 500 on the stock tt ecu and 550s I'm sold

i'm still trying to get my hands on an ecu, also had an other question might have asked before but for got, so if i us the usdm ecu an get high impedence 550 injectors i won't need to add in the resistor box right the ecu won't be looking for that at all?
All the Toyota ecu's (GE and GTE) are looking for high impedance, and there are 2 setups.
1 is like a stock gte, which has low impedance injectors and therefore needs the resistor box.
2 is like a stock ge, which uses high impedance injectors and therefore no resistor box is needed.
I am running high impedance 440's with the aristo ecu, no resistor box and using the factory SC injector wiring, didn't even have to change it at all straight plug and play. The only time you have to changed the SC wiring for injectors is if you want to use low impedance with the resistor box (as in you will need to wire in the resistor box), or if your injectors happen to have different connector clips than stock which can happen with both high or low impedance (but there are plug in adapters for most types online if you want to avoid rewiring clips).

exactly, if you do it right its not that much wiring. I only ran 2 extra wires to the ignitor, and the wires from the ignitor to the coils. everything else is a simple pin swap, or jump at the ecu connector.
Since you are using a usdm ecu, you will also be adding 3 new wires for the map sensor since you need your stock maf wires for the TT maf.
Jdm can just reuse the maf wires for the map sensor and iat as there is no maf.

you can do that as long as you have a crank sensor on the oil pump, otherwise you will need to swap to the newer style oil pump, but be sure to always use a ge oil pump on the ge block. gte pumps give too much pressure for a ge block, and a head swap doesn't change that.
