Hello, I have an 82' yoti and I'm swapping my 22r carbed motor for a newer 22re. My question is do I have to get a Toyota ecu for the fuel injection or are there others that I can use? Me and my boss are doing the swap at work and he worked for precision turbo for 6 years so we plan on eventually turboing the motor. But that will come later. So are there any stand alone fuel management systems I can use besides buying a Toyota ecu and wiring harness? Thanks
