Thread: Rovergauge MAF diagnostics

I have a fully 3.9 with 14CUX which is running far to rich after full re-build and Gas removal.

Everythhing points to ECU over fuelling. Adjusting CO trim on MAF improves situation but still won't idle and obviosley won't run well on load.

Downloaded and hooked up rovergauge and at 1200-1500 rpm am getting approx 45% on the direct scale. which matches readings from my DVMM.
but on linear scale i get no reading at all.(unlike pic below) As i understand it this should read a percantage of total air capacity.

just wondered if anyone has has some readings from a known to be correct MAF.

Thanks in advance

I have same issue with no linear maf reading. Car is running ok. Not overly rich.
