shouldnt the map in and map out be the same on idle cos its putting more fuel into the motor.

i just installed one of these in mine and it runs really rich on idle, will foul plugs in a few mins of idling, but as soon as its driving its absolutley fine, had it on the dyno and graph was perfect all the way through (apart from idle) for 240rwk.

Ideally yes.

Measured the resistance of the resistors? (powered off)

mine started to missfire within 10minutes of having it installed, i have since removed it and the car is running sweet, i compressed my wastegate spring so now it doesnt hit boost cut but still makes 14psi of boost

There is a thread on soarer central about FCD's for 1J's using 8 diodes in line wired across the pressure signal wire to the ECU and a ground wire, I made one and it is cheap and works with no other adverse effects.
Here is the thread, Phil Stuart is the poster who's FCD I copied.
