Stock R32/r33 Afm

[DFAULT]

HI, i'm just wondering when do stock r32/r33 AFM max out

could ya post up your dyno results of your car with stock afm

cheers

R32 afm maxed out at around 170rwkw for me

[salad]

yep, i can confirm this too.

i have 170rwkw now and the AFM is maxed out (R32)

this was also confirmed by sam aka dr drift

[DFAULT]

cool thanks a heap guys

[DFAULT]

Then when do r33 AFM max out?

[ronald_r32]

what do you go to when it's maxed out?

[limpus]

^^ Z32 afm...

[Gts-t]

^^ Z32 afm...

I made 206rwkw with the r32 stocker, its not the best approach though so get a bosch z32. Infact joel has a group buy going at the momment!

[Sass]

r33 stock maxes out at 250rwkw

z32 should max out around 350rwkw ish

q45 should max out around 500rwkw ish

[ronald_r32]

if you get a z32 do you need a power FC or anything like that?

[R31Nismoid]

yep, dont work with a stock ECU... unless its re-mapped i think then you can (r32)

[ronald_r32]

funny you say that about remapping, cause no-one bloody does it down here in tassie

Does an Apexi Air Flow Controller do anything about the stock AFM max out point?

[R32_GTS-4]

im upto 212.9kw on the stock afm....

wow, is that at the fly or the wheels?

It looks to me like the SAFC stops making any adjustments when the AFM maxes out. I have noticed on my car that when you recall the peak figures on the SAFC it says that the correction is 0% when the AFM voltage shows 100%, even though it is set to make corrections to the AFM signal from 2000 - 7000 rpm.

Of course I haven't been able to watch it in real time at 5000rpm+ on the road

There is not a black and white answer to this question. Just because the AFM reaches 5.1 volts output doesn't always mean it has to be changed

The only time you really need an AFM upgrade is when unanticipateable changes in airflow occur, ie; not linear with rpm changes. At high rpm (ie; past boost build and camshaft timing effects) this shouldn't be an issue. The fuel and ignition requirements are satisfactorily driven off the rpm change.

Keeping the above in mind, I have seen an RB30 run quite happily on an RB20 AFM at 265 rwkw. I have also had to change an RB25 AFM at 225 rwkw because the airflow changes where unpredicable (ie; not linear with rpm).

i was wondering if there are any other AFM (domestic cars) that would work. something mass more common, hence cheaper, even if it needed a dongle/electronics to make it look like something the ecu's expect.

I thought SAFC is to map fuel air ratio? it's got nothing to do with the afm capacity....if the afm can only read so much voltage...then that's the limmit SAFC or not~~

yes that is how i understand it, so if you have a safc and you max out the afm you would have to upgrade the afm to a bigger 1.
