is 24lbs max reading for the AFM? s4 t2 rtek 2.1, trouble shooting lean in boost
rtek 2.1
while troubleshooting, with the car not running but on I pressed the afm all the way in and it moved linearly, but maxed out at about 24lbs, temps were about 70 deg, at an altitude of 300 ft.
which is about 2/3 up the graph, and even on my safc it shows it as about 66%
on some old logs which were in cfm it would max out at around 900 cfm near the top of the scale. having trouble pulling the new logs up on the computer.
problem ive been having, car ran great, just suddenly this week it runs pretty lean at part throttle- full throttle when going into boost. a/f get into high 13-14 and doesn't make much power.
it did this same thing a couple yrs ago, I checked many things and re loaded the map and it went away...
map, temp, air temp, tps all are functioning correctly. fuel pressure is normal. tried reloading map and it still is doing it.
I noticed if I added fuel( which modifies the afm signal ) with the safc it will richen up as it should. and power is restored, roughly.

unplugged and repluged ecu and afm in a couple times, and reading was up to 730, which seemed lower than the 900 I remember years ago. tested two toher AFM and they all read 730 max as well. I used the FSM procedure for the AFM and my old one failed some of the readings, and this other one passed so I swaped it on and it ran great. I suspect the AFM was going bad.
