Does anyone know if the IS300 Standalone ECU’s are compatible to put in the 98’ SC300 2JZGE VVTI. I want to ask please help if possible.
so you’re saying I can get a EMU Black ECU with a harness from Tweaked performance? I know there was a few differences with the IS300 harness I forgot what they were. I know it’s a stupid question to ask but it’s best to ask now then regret buying it.Most modern aftermarket ECU will run the VVTI motor but any harness particular to the IS300 might need to be modified to work for the SC.
I kinda figured. And I appreciate it I did more research and yeah I did go with Tweak’d performance and it’s more convenient also. Thank you. I did some wiring myself but I didn’t have time so I ended up just buying one.The wiring harnesses are different as are the ECU's. So the IS300 kit does not work in the late 90's SC/GS. If you're not into doing the wiring yourself I'd strongly recommend having an adapter harness made for you by a place like Tweak'd performance or similar.
