Faq: Apexi Powerfc - Frequently Asked Questions

Recommended Posts

My car is in the shop at the moment and the guys are unable to get the ecu to communicate withe PC. Not 100% sure on the issue but will find out more tomorrow.

They are waiting on a reply from fc datalogit but from what I have read I dont think I should hold my breath.

How did you go with this?

I put my new one in today and the version 7 power fc wont communicate, but I just had to send a scan (FC-Edit did this automatically) in an email to the guys at fc-datalogit and am just awaiting a reply. But if you have answers before they get back to me it will be great so I can put my tune into the new Power FC

Can't edit so I will do another post.

FYI Paul, if you want to put it in the FAQ, for a version 7.00 Power FC for RB25DET (AKA the new release ones) you need FC-Edit Version 2.130k for the ECU to talk to FC Edit :)

Hi,

Will you update the FAQ on apexi's release of new PFC's with d-jethro for RB25DET ECR33 ? The part number is 4E14BN32 and fits series 1&2. Finally gts-t owners can get rid of the AFM unit and still keep the NVCS system(since RB26DET pfc d-jethro conversions lost that feature).

hi sorry for the mega late reply. i can but i need someone who has this model in their car. the main things i am after is ETC, VERSION - SENSOR SW CHECK and also SETTING, AIRFLOW (or SENSOR)

some screen shots will help for the FAQ as these are the main content items to include. so if someone has this model working with photos i can put it up

What are the reasons that a power fc would make the engine light flash.

Most common will be knock....

May also flash due to injectors maxing out etc etc

Is covered in full in the Apexi FAQ.... Many many topics on this.

Helo. Quick question. If I have a q45afm and power fc. How come my car runs a lot nicer when I select r33afm in settings,Apart from the lite popping at idle. When I select q45 it runs like shit, there's too much fuel everywhere idle and boost. The only plus side is it has a lot smoother idle although richer 11.0.

All this is the same if I load a previous owners tune or if I load a sample map or even if I data init.

in case this helps others,

Hey mate thanks so much for all the guides you provide they are invaluable. i am trying to figure out why the second hand pfc i have is getting stuck on the apexi splash screen.
the ecu says FC1 r33 inside the shell and PFC rb26 9811-0011 on the outside of the shell.
Does this ECU need the FCC NT hand controller?
the one i was sent is FCC3 010-00722
are there any other reasons it would freeze on the apexi logo if these are indeed compatible.
regards

yes you need either FCC NT or FCC4

if you goto nengun.com you can buy the EL hand controller brand new as it works on all PFC versions (it's FCC4)

FCC2/FCC3 are hard set for the newer PFC's

that is, PFCs with RB26XXXXXX as the serial are older style PFCS and PFCS with serial ECR33-XXXXXX (or BCNR33-XXXXX) are newer style PFCs

same functionality, same features, different firmware.

the PFCS that are RB26XXXXXX were sold seperately with hand controller where as PFCs with BCNR33-XXXXXX (for example) were sold as PFC and hand controller bundle

basically apexi made original PFCS to suit the engine then the "newer style" were sold to suit CHASSIS instead of engine code

so

PFC RB26-XXXXXXX (old, needs FCC NT or FCC4)

to

PFC BNR34-XXXXXXXX (new, needs FCC3 or FCC4)

Hey Guys, Just switched to larger injectors.

Needed to go in and update the latency and cc's. I dont have a commander.

Friend dropped by with his Commander and Datalogit. Commander is universal.

We can not get either one of them to connect to my ecu.

Power to Pin 58, 12v.

Motor is an RB25 S2 in it.

Any ideas?


Car runs perfectly fine, just wont connect to either piece.

    • The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.
    • 8v - 2.48ms 9v - 2.15ms 10v - 1.74ms 11v - 1.41ms 12v - 1.15ms 13v - 0.99ms 14v - 0.89ms 15v - 0.82ms 16v - 0.81ms I'm running these values on my RB20 Neo with 570cc Denso R35 stock jets and it's great. Also bought a set for my Legnum VR4, love these injectors!
    • Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!  
    • So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
