MR30 AFM pinouts

[Bugle]

Hey does anyone have MR30 AFM pinouts? or any other R30 if they actually have the same AFM. Thanks

Can get - tomorrow (manual is at home)

Anything in particular, or just the whole pinout thing?

[Bugle]

Thanks!

Yeah just what each wire does coming off the AFM. Like signal/ground/power and whatever the rest are.

25 - Air Temp

32 - Air Mass (variable output)

33 - Reference (?)

34 - +V

35 - ?

All the pinouts connect directly into the ECU, so it's difficult to determine exactly from the wiring schematic what some do.

Hope that helps.

If you like, pm me with a fax contact, and I can send the diagram to you.

Thanks for that

Air mass would have to be the airflow signal I guess? 33 and 35 are probably grounds? Other AFM's seem to have a power ground and a signal ground. I should be able to figure that out using a multimeter anyway

is reference used for the screw on the AFM? i think it adjusts the base A/F ratio calibration

i would like to know more about it actually cos mine has been tinkered with by datrally to allow for the increase in capacity
