Toyota Supra 2JZ and FCD Problem

[StarletMad]

Fit a FCD to a Supra today and its overfuelling like crazy ... unplug it it stops ... Plug the FCD back in and it immidiately starts overfuelling again...

Any ideas?

Its set to 9 by the way.

set it to 12 which should be off, and see what it does?

sounds like its wired up wrong to me

triple checked it and cross referenced it to diagrams pinout 62 on a Jz80 2jz if im correct ?

overfueling???? i thought a fuel cut defender was suppose to trick your ecu into thinking that you are still at standard boost when you are running above standard boost as far as i know it has nothing to do with fueling they only suply a voltage like a resistor the standard boost solenoid creates a voltage and the higher boost the higher voltage so the fcd comes in and keeps the voltage down so the ecu thinks your at standard boost hope you get it sorted anyway

Yeah man i know its confusing the hell outta me.

Fitted MS-ibc to it also its only running 0.9Bar

But there Sequential turbos so only the secondary turbo has the ebc on it as the other is there to reduce lag time.

:/

Just seems wierd that with the FCD in its chucking shit loads of fuel in its like black smoke on idle
