I have a used fast b2b system. I need to know which color inj wires go to which injectors. I have a yellow green brown & black wires. I called fast & they couldn't give me a clear answer. I can get the car to crank & idle but no more. Anything off an idle it goes to missing. THe WBO2 shows its lean when it does this but the motor is belching out the black smoke. things i have already changed are checked is the Ignition system. Fuelinjectors IT uses a crank trigger so that eliminates the dist. plugs, wires. Car does not lose fuel pressure when it does this either. THanks in advance.

 

the back to bank is batch fire and not the sequential ... therefore it doesnt matter which injector wire goes where they fire all at once.

they do not fire all at once. on there website it says the system fires half the injectors every 180 degrees of rotation.

the system comes with 8 injectors ... you're using 4 and eliminating the other 4.

best option is giving ecu number then you can check to see if itts a sequential box or b2b. Try to contact Craig Smith, he's the genius behind FAST.
