because most R33's with RB25 engines are running near max voltage after 200rwkw.

at 220 that you want, they will be past their resolution.

and series 1 to series 2 AFM are slightly different. but still max out at the same level.

you are changing the afm. might as well start with the right one instead of having to change it again in the future.

my car is making ~250rwkw on the stock afm :(

that's why I said most.

and did you tune it?

did you see it being tuned?

do you have a PFC hand controller where you can see the AFM voltage?

is it not hitting max (4.8 or whatever it is) way before redline?

You can tune the car still once it has passed max voltage..

but it's not as accurate.

which kinda defeats the purpose of having an AFM equipt car..

and it is kinda in the zone where you would want to place the most emphasis on getting the tune right.

from wat i have read on here the R33 s2 pins , 2 of then are for grounding ! can anyone comfirm !

No thats not correct.

The S2 pink label R33 AFM has 3 terminals. With the AFM facing towards you and the flow arrow pointing ===> they are:

pin 1: 12v from eccs relay

pin 2: Ground

pin 3: Signal

The Green label R33 S1 AFM however uses 2 grounds. The first is an ECU ground, the second is a Chassis ground. This is the same scope and dimensions as a rb20det silvertop AFM, the terminal outputs are slightly different but both 80mm.

Here is something a found on the net ages ago that I dig up when I need it:

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
