Having a spot of trouble getting my head round the AFM thing. RB20DET PFC like all has 5 AFM options. Yet when you check next to the appropriate one nothing changes?

What does the figure next to the AFM volt setting indicate?

Gee that will help...

Will have a look at mine at lunch, you have it set to VG30 80mm I take it

Hi TT, my understanding is that those numbers refer to the 5th Option in which you plug in your own polynomial:cheers:

Hi TT, it's my understanding that it's for Option #5 so you can set up your own polynomial:cheers:

As far as I can see, the voltage reading with 100% along side refers to the fuel map... So if I want to lean off when the AFM output is ie; 1.28v then I ramp that number 100 down.... so effectively the A/F will be say 95% leaner at that point. The 13b looks like it uses PIM rather than AFM, but the end result is the same.

The actual air flow curves are different... Datalogit people may only know what I am talking about. And yes Skid, If I wanted to run a MkIII pulminator for AFM then I could form my own curve...

Not thick down 'ere, but slow sometimes. :idea:

Funny, yesterday I was playing around with my PFC to see what your on about TT :D

I must have left it set to option 5 in the AFM setting, as the car wouldn't idle at all, then I realised I must have not set it back! :D

But I think SK and TT are spot on, its there to setup your own curve

Also, just a quick PFC Q while I have most of the other RB20 PFC owners here, the knock sensor function - is it possible to set the 'check engine' light to come on earlier or later? I wasn't sure if this was adjsutable, and cannot find a option to change it

Cheers, Chris

Hi Chris, knock sensor is adjustable, there is a threshold (0 to 100) and a setting (0 to 9 , I think as I have never adjusted it). Usual threshold is 60, and flash is set to 9. This flash interval is so you can tell what sensor the Engine Warning light is flashing for. They are located in the Settings menu but it has been a while since I used the Commander to do it, the Datalogit is so much easier.

Hope that helps:cheers:

Ok I will have a look, cheers!

any chance you can have a look at this question I posted, your input would be a huge help - http://www.skylinesaustralia.com/forums/sh...ead.php?t=54225

    • I made a little more progress last night and added some E85 safe fuel tank baffle foam in behind the stock cam cover baffle plate.  It still feels really wrong shoving foam inside the engine but apparently its fine based on it pretty much being the MINES/Hi-Octane RB26 cam baffle kit and the few posts here I have found of people doing it and the lack of posts saying the foam broke down and ruined the motor... Still plan to check it frequently though lol The last step for this round of oil control modifications I plan to make is to add some -12AN fittings to the cam covers and connect them to some (already existing luckily) -12AN fittings on the sump. Basically a sudo head drain/sump breather/pressure equaliser without having to remove the motor and do the one on the rear of the head. My plan is to add them to either the tops or the sides of the cam covers at the back. unless there is a compelling reason to have them at the front on the sides which i have seen a few times though they were all on RB26 cam covers from memory so that may be due to the stock breathers being on the back and the integral baffle being different ?    
    • from an old insurance company i was with (Budget Direct) I had someone roll back into me at the lights got them to pull over. Got a picture of thier licence with address, had a dash cam video and, thier phone number. But only had 3rd party on the shitbox i was driving. insurance did nothing, cops wouldn't do anything due to the value of the damage (under $3000) so i just had to suck it up and go to U Pull It. 
    • Small Update on the Exhaust Situation A 200-cell cat was a bit too expensive for now, so I had the exhaust shop fabricate a new exhaust from the cat to the rear and an exhaust tip. I went this route to avoid cutting into the original exhaust and keep it intact. It’s essentially straight-piped, and the sound is noticeably different. The exhaust tip came with a silencer, so if it gets too loud, I can easily install it to tone things down slightly. Right now, the car bangs and pops like crazy -- which I personally love. In the future, I might add a resonator or a 200-cell cat, as niZmO_Man suggested, but for now, I’m really happy with how it turned out.  
    • And that's a massive problem, because deadshits will deadshit and give you false details. At least in these days of mobile cameraphones, it is trivial to take photos of any ID they are carrying at the same time as the 300 photo extensive documentation of the state of the vehicles that I recommend even for minor incidents. And you get photos of the person's face, any visible tatoos, etc etc, while you're at it. Then you try to avoid mentioning that you're fully capable of making explosives of various power levels and will wreck their shit if you are forced to hunt them down.
