the faq covers "hung on apexi logo"

15volts its too high, dead fuse for regulator circuit (i had this problem in my 33) theres a fuse in the boot for the regulator signal, its dead or removed, check it. engine light will only be on if you use boost kit without actually having the boost kit, it sounds like it may have done factory reset. if so turn off the boost kit under ETC, FUNCTION SELECT.

are you in melbourne ?

and unfortunately i cant do much with it as i dont have a commander for this. There are 2 types of hand controllers and it seems i can only get my hand on the wrong one!! thats why the apexi logo hangs. Also found out that a couple of people who have had to jump start or had dead flat batteries with power fc's have lost their maps in the process.... I fear that this will be my fate too. Flat broke so if that is the case the ol 33 wont be on the road for quite some time!! lol Getting alternator back tonight from a reco (needed it bad!!) so will put that back on and let you know what she's up to from there!!

you wont loose the map if your battery is flat or if you jump start it. the tune is saved in nvram. i fried my powerfc (blew it up by shorting the wrong wires) and i had it repaird by a friend at work and my tune was still present.

i have datalogit so i can access your powerfc but i can't tune it for you (no dyno). dr drift in melbourne has access to datalogit (and dyno) and he can tune it for you no problems. it just may take longer with no hand controller

give him a call

added djetro info for other djetro models (evo lancer, s15 200sx, gtr)

added wideband tuning

added full menu options for all powerfcs

added idle hunt / idle surge fix

added FUNCTION on / off japanese character key

updated some of the self tuning for ignition timing areas

updated idle reset procedure

updated info for apexi powerfc pro discontinued

an important update is coming soon

re: starting issues with 414-AN012 (was a once off problem, not a bug)

active lsd on ecr33 FIX

for those active lsd customers check out http://www.skylinesaustralia.com/forums/in...pic=107656&st=0

Ok, got regualtor fixed, reco'd the alternator only to read your post about fuse, and guess what.... you were DEAD RIGHT!!!! Replaced fuse, all is good, still have the engine problem though. Seems ok under load, off load (ie: cruising at set speeds) it misses and farts at a certain interval, like every 3 seconds, it farts for 1 second, then fine for 3 seconds, then farts for a second and so forth. Finally got hold of a hand controller thats for an r33, and ......NOTHING! Apexi logo hangs, but i did find that if i hold up button whilst turning ignition key on it goes to a screen that just says "FN" ????

Think i may have fried some or all of the power fc? Googled the shit outta "power fc FN" etc only to come up with didly squat...nothin!!!! Help me please!! lol So far you've been spot on the money! If need be i'll express post it to you and you may be able to fix it!! lol, the problem i have is its supposed to be in a wedding march 18th!!!! not looking too good!!

i have tried looking into all of that, what i've found is this, which is just what "i think may be right".

That for r33 skylines there are in fact 2 power fc's around for them, one is serial ECR33 XXXXXX and the other is RB25 XXXXXX, the ecr33 one uses the hand controller FCC3 XXXXXXX and it looks like the RB25 (my one) uses a controller FCC NT XXXXXX

I cannot see anything on the controllers or power fc units stating numbers anywhere near 414 N001 or X001. Mine says PFC RB25 -9705 - 0013 on the unit and the hand controller says FCC3-020-10512

Man, im glad you've got the brains to figure out this stuff!! That bloody FAQ you've done is a credit to ya and it would have taken a LONG LONG time to get to the stage its at!!

so the pink & black soleniod wiring is wired into the factory soleniod loom green & blue/white wires ? is this correct ?

is the z32 afm from the vg30 engine, so what voltage value do i use ?

Also ive got 555cc nismo injectors, what value do i need to use in the injector value menu ?

Hi Paul,

Just a though here, don't shoot me down in flames :laugh:

How about you add a section on doing full power ignition tuning? As long as you have a good set of knock headphones, it isnt too hard. I know of a few cars that have been 'street tuned' this way with a wideband O2 meter as well.

Cheers,

Matt

whilst i wouldnt mind myself

its basically a case of up timing and watch for knock

i can put lots of stress on the car

and also its a big change of the tuner "amatuer" to really bork the engine.

i would rather a pro do that part if it makes sense

very interesting read, thanks for all the info, i have tried some of it, but im still not confident im doing the right things. Anyone in Sydney know a cheap place to tune the power fc properly ?

im assuming rb20 powerfc would suit which is an ap engineering model.

the 4wd controller system is performed by a seperate computer to the ecu. you may find the tps signals and rpm have to be run manually as the rb20 ap engineer wont expect to have an attessa ecu piggyback-ing off it

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
