Have i got a problem?

Mihnea, at what point do you suspect a maf to be faulty? You obviously have enough expereince to know, but what can we do other than watch out for a drop in our peaks by logging? I mean my 260 is a lot lower than some, but also not bad I dont think- but I don't have logs from when it was first fitted, so don't know if it has ever been any higher.

If you suspect a faulty MAF and unplug it to see how it feels, what happens if you log block 003 or any other block with maf reading? Do you get a reading of any sort? Can this be compared to with it plugged in to conclude anything?

Dead MAF judging by those readings!!!!

Du u recon? Worth getting a new one then?

Before you buy a new one I think it is worth doing some more runs, logging just the one block 003.
Perhaps this will give better resolution, I wonder if we missed the peak MAF due to the sampling - as we were logging other blocks at the time.

I'm not even looking at peak MAF, only the value at 5600 RPM says it's seriously underreading. The peak could well be lower but if the whole RPM range is lower, then dead it is

[GrahamS4]

At 5600rpm my maf reading is about 250-253. Would you class that as healthy?

Out of interest was the performance panel filter oiled?

Slightly but not lots. Very slightly.
