Any Power Fc Hints?

[Robo's]

I have just put a Power Fc in my car and have been studying the maps. Ignition maps go between 42 degrees at very light throtte to some 20 degrees at full throttle. At the moment with the boost wound down, i get ping of around 30 under full throttle. I know i need a session on the dyno but i want to have a play.

Idle is varied, rolling to a standstill, i get a fluctuating idle between 1000 & 1200rpm until i get to a full stop, then it settles around the 700rpm which iits set. Sometimes at idle it likes to hunt, which i dont like.

Im running a Z32 AFM, and the setting for the Air Flow is the 3rd one, not R33 normal or super intake.

Any more hints?

make sure you have the 02 feed back circuit enabled or you will end uo the a hugh fuel bill like a friend of my r34 gtr ,he had tune a number of time but could understand why it used so much fuel ,the tuner had not turn on the o2 control and so it ran purely off the maps

Thats the way my PFC is running because if I turn the O2 control on the car surges at constant throttle. My gas mileage is very bad.

Dont leave your hand controller in the summer sun / dash. LCD screen will go really dark.

leave it in the glove box when not driving.

my first guess would be u/s 02 sensor and that why your gas mileage is bad

go to sensor check function and see what the v reading is(should be pretty stable)

around mmm tring to remember 0.9v at idol (i think) someone else might remember of the top of there head
