So this may be a noob question especially since I am one..Im new to these cars and I have a 90 GSX motor in my 91 VR4 and my current ECU is F***** so i was wondering if this would be a workable replacement and how much is involved in running this and if i should just go with something more basic considering how new i am to this vehicle. i have a 16g big turbo, and almost 9k into the motor but none of the work done by me personally
