i bought a car with this ecu but it wasnt wired up completly or correctly and i have since solved many wiring faults but am still struggling to get anywhere.
Currently i have 12v at INJ1 on the ECU and at both pins on the injector plugs its wired so it batch fires all 4 injectors but this doesnt seem correct and this doesnt change when cranking.
Ignition wise i have 0v at ING1 and ING2 when not cranking then i get 12v as soon as i start cranking the engine and sometimes it drops to 10v every so often. At the dual channel ignitor i get 3-6v on the output when i start cranking then 11v straight after i stop cranking which slowly drops back to 0v after a little.
I have checked the wiring over and over and cant see anything wrong. The ECU switches the fuel pump relay as soon as cranking starts so i can only assume its getting triggering but as i dont have the hand controller i dont really know.
the car is a 3S-GTE running wasted spark with two coils off a 7M-GTE supra engine if that helps any.
thanks david
