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

oh cool what car is it !!

S1 have 5 pins, and S2 have a green sticker with 3 pins. Well the ones in my garage do anyway...

[QUICKY]

actually s2 have a pink sticker

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.

i do have a pfc , i installed it but idled pretty bad to a point car wouldnt of been drivable lol so gonna leave it for tune only got pfc rb25 and 550cc injectors afm for now anyway

actually s2 have a pink sticker

thats what i thought too mine is pink !

[kurd_boi]

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:

thats a really good pic man cheers im sure will help others out

not meaning to hijack this thread..

Just wondering can you put a Z32 AFM on a R33 S1 running a stock ecu?
