Paul,

Would a dodgy AFM cause major knocking in the range of 70-90?

unlikely so i would say no, read the PFC FAQ

theres lots of topics covering knocking and how to test and deal with it

Does a power fc'd skyline need regular "tuning", like changing the oil every 5000 ks?

of course

normal maitenance should still apply for the car

if the car is putting out significantly more power than std more attention should be given to service intervals and quality of fluids, items used etc

Is there a way of disabling one cylinder through the power fc making the whole engine run on 5 cylinders?

Went to get my car tuned, but they never tuned it as my engine was running 5 cylinders.

there is no such feature, the only way you could achieve this would be to unplug one of the coil pack leads

Hey paul,

I've notcied that on my powerfc controller that my knock "figure" has disappeared... I still get the knock bar I just dont get the knock value. Any suggestions?

This problem only happened when i was driving home in flooded roads and I had hit something which made a pretty big thump but at low speed (mabye 10-20km/h) which has then caused my immobiliser light to come on whilst driving and now my alarm/immobiliser doesnt work.... Would this have something to do with the missing knock figure because I havent touched the pfc controller since I got it tuned...

Hey guys i have just put a power FC In my R33 and i am having trouble with the fuel and ignition map when i adjust them and then select previous and exit the maps then return to the maps the adjustments i made are gone just wondering if any one can help me

when viewing knock in 1 CHANNEL display press UP for digital top score

i've replied to your pm - when you edit a value on the INJ or IGN map you need to confirm the change with NEXT (PREV will back the change out)

so edit the value, press NEXT and it will save the change you have made

Any other recommendations for a unstable and sometimes high idle (1000rpm)

I have leaned the idle right out and it definately helps when rolling to the lights as before it used to rev up and down. Now at idle, sometimes its fine at 700rpm but generally its around 900/1000rpm and sometimes back to 700rpm, but the majority of the time its high, seems to have a mind of its own.

Any recommendations as i dont want to reset it.

Hey,

With a r32 gtst and rb26dett ecu.. I am having troubles with speed read out. It sais up to 900km per hour when only doing 100 sometimes it works good and others none at all. Any idea??

when you encounter the high RPM issue check out SENSOR SW CHECK and see if anything out of the ordinary happens

maybe leave that screen open and watch if you see the issue about to occur

other than that all i can suggest is maybe clean AAC, check leaks etc, check TPS, check throttle body

read the nissan service manual for idle related issues and lastly a reset as a last resort (get someone to copy the tune before you do)

Not sure if this has been asked but I don't have time to read through 21 pages so...

Can the 3 or 5 pin harness for the boost reading work on any pfc or just the d-jetro? Also, what else do I need to hook it up apart from this harness? Vacuum hose etc??

hello stranger

:P Small world isnt it!

Im quite sure you can use the boost reading on any pfc. I know mine is 3 pin and the socket is on the back somewhere. In my pfc boost controll kit it came with the sensor, which is wired in and hooked up to the manifold pressure. Im unsure of the signal type this sensor uses and what else you could use but i imagine there'd be something else out there. . . .

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
