guys, just fitted power fc to my r34 gtr. it wont run.....

i have turned off the boost control kit and checked that the ecu plug is all the way home.

i run 700cc sard injectors so i have set them to 63% and +0.02ms in the inj menu.

i am using 300zx afms and they are reading .45volts then .8volts when engine is turned over.

when turning the engine over i get 4deg timing and zero injector pulse in the monitor section of the pfc... bugger..

my car will run with the mines ecu with these afms so they seem okay....

any tricks...???

might need an r34 gtr ecu wiring diag if anyone has one...

someone told me to change injector lag to .30ms would this help.....???

hi markr34gtr,

I'm only having a guess, but are you having the same problem as aurospeed did with their PFC... see http://www.autospeed.com/cms/A_0301/article.html

Apparantley all PFC come pre programmed assuming the Electronic Boost Control is fitted, once they said no EBC is fitted the car ran perfectly.

another thing i noticed was on the ignition switch there is a small unit with 4 wires that was unplugged..

i plugged it in but made no differnce..

could this be the key code reader for the immobiler....

maybe this cuts fuel and timing....but lets it wind over....

funny as it runs with the mines ecu and these wires on the ignition switch unplugged or plugged in...

hmmmz if you can afford a 34 GTR you can afford a proper performance shop to stuff around with it? :)

thats why i can afford a r34 gtr is cause i am a qualified mechanic...

and try to sort out my own problembs not just give up and get ripped of at some workshop.. and they say oh well we cant fix it but heres a bill for 1 grand for our time...

so i think comments like yours you should keep in your head...

there are guys here you all help each other with there experiances........
