Maxed out AFM but not Injectors?

[3R1K]

Hi,

I just realised yesterday I maxed out my AFM at 5.024 mV but my Injectors duty is 67%.

Does that mean time for z32 afm? I'm using power fc.

You're making about 200rwkw correct?

If the voltage is maxed out it sure does.

Time for the Z32 item.

I was making 200 rwkw but not now, It's more like 180-190 kw I'm not too sure.

It's just so weird for me, or is it because of dirty afm?

was it a once off or constant? i asked the same thing about a month ago try a search for it, got a few good replies covering maxing afm and injectors. as long as its only a once off it should be ok, like if its maxes from say 4000rpm onwards then its bad

Your am will not be able to read any more air once it gets past 5.12volts so you are very close indeed but the ecu still knows how much fuel to use at 5.024(not much resolution left though).

Once it reaches 5.12volts any more air will not be metered.
