Is My Power Fc Blown?

[toy515]

hey guys i have a power fc in my s15 rb26 and ive recently taken the engine and gearbox out, the loom is still in the engine bay. and ive still got my battery hooked up so my alarm works, but when i turn my car to accessories to put my windows up my hand controller doesnt come on, is it because my loom isnt pluged in? or maybe a fuse or is my power fc rooted? it was fine before my engine come out

cheers

i have a sinking feeling it may be. although I don't think the PFC boots up on ACC only when the key is turned to ON.

I recently farked mine and the HC lights up but the screen doesn't come on and engine won't fire... d'oh!

yeah the FC boots up and the hand controller boots when ignition is turned to ON

usually if the FC is blown it will boot the hand controller (if it has power) and display blank or scrambled rubbish

open it up and smell for burnt stuff or check for burnt tracks

I almost posted last night to check if the constant power to the ecu wasnt d/c when the engine was taken out.... Seemed too obvious tho.

I got a question for you. On my Rb25 I have a Power fc with hand controller, when I first had it installed the hand controller would come up fine showing all the channels and information. now when I turn my car on it just shows the APexi PowerFC logo and just sits there. Likes it frozen .. no scrambling info - just the logo appears and just stays there. Any help ?

wouldnt the fuses blow before the power fc?

Not neccesarily

Not neccesarily

word. seen it happy many a time. fuses fine, PFC toast.

Power FCs are much more sensitive than standard ecu often with a weak ground or weak power supply stock ecu works fine, power fc doesn't. and same goes if you get a short circuit. often standard ecu fine, power FC not so fine. i have nfi why, but that's the way it is.

Hey Mate,

Recently bought a Power FC from a bloke who had his engine out as well - everything else was in the car. We tried to fire it up so I could see if it was working prior to purchase and it didn't work. Put it in my car and it worked fine...we concluded that the other end of the wiring loom needs to be connected to the engine for the Power FC to work...

I don't know if this is technically right, but it happended with me - hope it's the same with your situation as well.
