I've got an 83 280z Turbo and have been asked to install a Gotech MFI unit to help control the injectors and fuel system. I have already put a AFR. built motor low compression. car has an MSD boost timing module. I need to find crank signal, I tried using crank signal from the BTM but no luck. I dont usually work on these types of cars, usually much newer cars. I also didnt build this car. I would love to start from the ground up and start over but not gonna happen. any help would be greatly appreciated. thanks.
