im not getting spark on cylinders 1,3 and 5

is it possible that this could be a problem with my powerfc itself?

does the PFC have some kind of diagnostic to check this?

No it doesnt have a diagnostic for that.

Your best bet would be to eliminate the basics first. Dont do too much diagnosis at once though. Take small steps.

1. check your plugs, see if the dead cylinders have wet (fuel) plugs. Consider swapping plugs between working and non-working cylinders to eliminate faulty parts.

2. swap coil packs around, for the same reason as above.

3. Try another ecu, or a standard one if you can get your hands on one.

3. consider pairing up cylinders for waste spark operation. This is done at the ignitor. 1+6, 5+2,3+4. As dodgy as it might sound you can try using a single paper clip to bridge the ignitor inputs. You will need a circuit diagram for your model engine. If it doesnt start to fire the dead cylinder using this method it could still not be getting fuel.

Good luck!

yea, after allot of trouble shooting today it looks like some cylinders might not be getting fuel

so i'll be checking that tommorow

I would assume that would be an ecu or injector wiring harness problem as the injectors are batch fire (3 at a time) would pay to check which injectors are wired together before you go pulling thinghs apart though is it may be different ones to the cylinders not getting fuel.

just checked the manual and i cant figure out what ones fire together, on page 351 it has a heap of technical things to check to find the problem, if you dont have it already do a google search, its around 460 pages and well worth downloading.

anyone know which 02 sensor is "02-2"on the sensor check screen mine is faulty and i got a rear 02 sensor so im hoping its the rear one can amyone comfirm? i tried unpluging it and looking bck at the power fc and it was stil giving a reading on both

yep the vhost that holds the PFC FAQ is broken

im trying to fix it (its not my server)

if i cant fix it i will get it moved to somewhere else so wont be down for too long

i still have the data so its not lost

it may take a few hours to propogate via DNS so if it doesnt load, try in a few hours

please be patient, it is still uploading so the images/links probably wont work for a few hours

Updated PFC FAQ

-updated Apexi PowerFC Wikipedia articile and PDF Snapshot

-updated Apexi PowerFC EL Hand controller and incuded video (thanks John)

You suck, you got me all excited thinking that the EL hand controller was all new and did something good, but it dosnt :P

yeah it looks the same as the normal FCC3 hand controller, just EL instead of backlit LCD

im yet to see one working in the flesh, the one on the demo video is just a screen loop and not a real unit in operation

    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers 
    • The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
