Hi,

did the aac valve clean and reset idle, but still havin a few probs.

the stalling at lights has now all but gone, so result there.

but the idle still hunts, between say 700 rpm and 800rpm? according to the power fc hand commander

seems worse when lights are on.

is this hunting worse with other owners cars, or about the same and i've not fixed the problem?

does anyone have any ideas?

all help greatly appreciated and will mean less dents in car :(

thanks for looking

I think it is quite normal that the idle will vary slightly. It's not really noticeable when watching the tacho, but when you see numbers changing, then it becomes obvious.

The fact that it is worse when the lights are on - which means the engine is under more load trying to drive the alternator - suggests a possible problem with an aging battery.

Thanks, i have been thinking perhaps battery or alternator, just dont wanna go spending a load of cash on bits that are ok, battery has been in car for the three yrs i've had it, so maybe time to change?

also have hks turbo timer fitted which reads voltage, seems to vary quickly (3 times a second or more) between 14.2 volts and 13.78 ish, would this point to a duff battery?

thanks again for the info m8 :D

not sure about the hunting when cold, mine still is ok when cold, someone must know tho' ??????

any ideas folks

Is it just when its cold? Ive heard unless its really well/extensively tuned, alot of cars with PFCs have a poor cold idle which is one of the reasons why people wish to retain original ecu and have it chipped (to keep cold tune) or add a piggyback

    • Haha luckily we don't have emissions, inspections, or any laws against power adders here. They only thing they somewhat keep an eye out for are ridiculously loud exhausts. 
    • 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!
