Hi all,

Just done some live data readings on my MY00 Turbo with some interesting results !

Long story short - can a MAF stop my O2 sensor working ?

Data Below:

OLD MAF v NEW MAF

MAF Volts 0.46 - 2.7 >< 0.3 - 2.9 (only went to 4k)

O2 Sensor 0.1 - 0.97 >< 0.000 - 0.005

O2 sensor was scaling up/down as I believe it should on idle with old MAF but as can see nothing on idle with new !

I think the old MAF is on way out as with the new one fitted whilst driving above 2.5k and on boost it feels better - but the readings suggest it too is cream crackered or am I missing something ?

Thanks as always,

wazlee

Did you reset the ECU after installing the MAF? It will take quite a while for it to re-learn the trims it uses off-boost and for the O2 sensor readings to start to oscillate.
