Had Vag-com on my car to see if there were any engine faults on it and it came out clear , then did MAF test and got a max reading of 157g/s can some1 tell me if this is high or low :confused:

Thanks KEL,

Is that 0.157g/s or 1.57 etc.

Normally at idle it should read between 2.5 - 4.5ish AIR

In my VRS (Revo 4 bar) with N75J and HB4 ...i have up to 167-170g/sec in the Vag-Com.

157 is OK (you have std Revo setting in boost??)

Ya it's just std Revo wit N75J and it runs at 1.1bar norm, max 1.3bar @ 3,500 rpm and after 5k rpm it drops to .8 bar it that the norm?

Any1 no wot a std MAF reads!

that figure is there or there abouts yes..

LCR and other 210/225 motors will put out 190g/s, chipped Ibiza/Leons 160g/s approx.

Here is my Block 003 data for Air Mass & Ignition timing.
