hello i have trouble with PLX SM AFR, when i add extra fuel, my gauge is show "LEAN", but must show "REACH".
voltage is 5v on d14 when is show lean

bad sensor or bad controller plx?
datalog and calibration with video

Re: trouble with plx sm afr
Do not use D14 as it cannot read the full voltage range. Use D10 or one of the other inputs instead.

my p28 is modified for read 0-5v on D14Spunkster wrote:Do not use D14 as it cannot read the full voltage range. Use D10 or one of the other inputs instead.
i can set fuel in calibration and my engine work in IDLE on 19-20 afr
if i set more fuel and my afr less then 10.5~11 PLX is showing LEAN, if i decrease fuel ~% and my AFR more then ~10.5-11 PLX is show actual AFR

Without the calibration and a datalog it is impossible to speculate.

Re: trouble with plx sm afr
If you are referring t the 1 minute mark then it appears to be reading correctly as the voltage in put is around 5 volts and it is showing it is very lean.
If it is reading incorrectly on the PLX itself, you might want to contact them for assistance to determine why it is reading inversely.

i'm resolve problem.
replace WB sensor
