Jdm mkiv 2jz Ecu on 1jz

[viperjames]

Iv been trying to search but came up with aristo Ecu's

My question is if I get the harness from dr tweak got jdm Ecu for a 2j into my 1jz harness do I have to do anything else if the Ecu is a jdm supra Ecu with manual transmission?

Fuel pump wiring?

Lots of info in aristo Ecu's with the neutral switch the fuel pump relay and gear selection but when it comes to a manual transmission is there anything more to it?

No one?

2jz ecu is set up for bigger injectors than 1jz, and different knock frequency due to the different engine size.
2JZ is also sequential injection, 1j is semi sequential.

ECU and harness must match the engine, or you are just gambling.

Auto-ecu's needs special tweaking regarding Neutral and park-switches on a manual setup.
Manual ECU's dont need anything special other than a fuel pump circuit that handles the PWM signal from the ECU.

PWM signal on FP wire is used on all 1JZ and 2JZ engines, with the exeption of JZA70.
