is it possible to check max values on a powerfc? if so.. how? and are they stored or do they get wiped when you turn on/off the car?

[ovaxitd]

push up button on hand controller gives max figures... once car is turned off you loose the data..

got the pfc boost controller kit in my chaser does any1 know how to adjust boost levels wit it thanks ?

[CHA54]

powerfc boost control is very very basic, you set your boost target and then adjust the solenoid duty cycle required to achieve it.

edit: more info on how to set it up here:

ok so i have now fitted power enterprise 800cc injectors (TH800A) and i need to adjust tune so car will idle and run, does any one know the latency of these injectors ? also is the factory injector latency of jzx100s .76msec ?

ive worked out the correction needs to be 45%

new latency(th800a) ???? - .76 = ?

any info would be great!!

[CHA54]

1.6msec according to http://power-enterpr.../fuel/fuel.html

Not sure what voltage that lag time is from though.

The powerfc manual states the stock jzx100 lag time is 0.76

thanks cha54 . I put in those calculations and it seams to run a lot less richer. however turbo mods all done and 800cc injectors fitted and car wont boost ? wat do use think could be the problem ? could it be the tune ? iscv has been blocked off and vacum line beneth it ?? , could the o2 be stuffed or afm ? turbo is a hypergear TR43hf internally gated. will post up pic of layout tomo. just wanna make sure its alright before i go to get it dynod.

"pfc was tune to stock injectors and standard turbo made 260rwhp on 12psi " before turbo died :S

[CHA54]

you run the risk of damaging your engine if you try and drive it without having it tuned, it's not hard to melt a piston. Hopefully you have a wideband installed if you're trying to drive it on the street with no tune and the new injectors, get it towed to the dyno.

The PFC injector correction settings are more to do with getting the car to idle correctly, the rest of the fuel map will need to be retuned.

Hey guys,

I need the pin out diagram for the power FC AUTO unit.

I currently have it in my Manual Chaser and its throwing an CEL apparently because its looking for a input from the auto trans?

I bought the PFC second hand so any help would be greatly appreciated!
