Well I just got my New Apex Power FC in the mail this morning and I went out pulled to stock ECU and pluged the PFC in. When I turned to key on nothing happend at all. No Check engine light illuminated and the comander isn't lighting up or showing anything at all. I checked the Model # to make sure it's the right one for my car. Crank the engine and it wouldn't start. :(

Is there somthing that needs to be done to the unit before it will work? I looked at the english manule from the Apexi webpage and didn't see any steps I missed.

dont put it in yourself. It best that the computer is put in by a mechanic and tuned straight away. I know someone that put it in himself with a new set of forged pistons. He drove it for a while untuned and bye bye new forged pistons.

my 2 cents

The plug is going in all the way. I am a mechanic by the way.

It's happened to me before... Just unplug it, check all the pins are still straight, and try plugging it back in again.

If it still doesn't fire up after a few tries, check the power wires going TO and FROM the PowerFC (yes the PowerFC has OUTBOUND power wires)...

Other than that, it could very well be buggered? It's just a straight plug-in, and it should turn on and let you switch off the boost control option (if you're not using the boost controller, you have to turn the option off in the menus, otherwise it won't start properly/idle)

Err, why pay for a mechanic to do it? IMHO that's just a waste of money since a PFC is essentially a plug and play device.

Sorry, but your friend was just stupid. Driving around on a base map with a rebuilt engine is a silly idea.

LW.

Do you know someone with the same car?

Try it in their and see if it fires up.

When i put my pfc in the engine would turn over but not start and it kept loosing any setting we would change. The solution was to put a new earth into the loom and that solved the problem.

Before the ground was put in the loom did the ECU work? Mine doesn't do anything at all. I tried running a ground wire to the ECU case and it didn't make any difference. So how did you figure to run the wire. Did you have to add an extra wire in the ECU conector?

I installed my PFC - simply unplugged the stock ECU, inserted plug into PFC then screwed the bolt down to lock the loom in. I certainly didn't need to earth it.

As for it being a "Plug and Play" device... sure it'll fire up, and even run enough to allow one to drive around, but the mixtures won't be anything near what is required. I can't see how the fool destroyed his motor driving it like that - if he was driving the car hard then I can, but people who fork out lots of money to rebuild a motor and install an ECU usually know a lot about the product they're paying for.

I've noticed that some PowerFCs uses it's metal case to ground itself.

You can't just have it lying on the carpet, you need to screw it into the bracket in the kick panel which will ground the unit.

Others I have seen have worked fine lying on the carpet, so I dunno?

Dude - check that your AFM is wired properly and the right setting for AFM are there. And also check that your AFM is working OK (ie swap with another one)

I just had exactly the same problem - swapped my AFM out and all good. I just don't know if my AFM is stuffed or my wiring was wrong cause I had a Q45 (didn't work) and changed to a VG30DE AFM (worked)

Good luck :D

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
