Thread: Nanocom values

My Disco TD5 had a surging problem at high reves when accelerating hard. Went recording with my newly aquired nanocom & found the MAF sensor reading dropping to zero for 2 seconds causing the surging. Disconnected the MAF plug & it ran great but soon found fuel economy severly worse. Cleaned the MAF out with contact cleaner, no more surging, recorded graphs were stable & fuel economy returned.
Could anyone tell me what reading to expect from the MAF. IT looks normal, climbs steadily to read about 200 then within 1 second gets to 600, then tops out at about 680. This may be normal but I'm a little suspicious of it as the default value on the Nanocom graphic viewer for the MAF needs to be doubled to fit the reading within view.

Try to use corrected graphic Viewer 1.02

(max value for Air Flow is equal 700)
