Air system part I: MAF
- Go into Engine measuring block 003
- Start Logging data
- In a high gear (4th/5th), give full throttle from 2500 rpm up to 3500rpm.
- Find and Open the Log file in Windows Explorer
- Graph MAF actual -vs- rpm in Excel
- The MAF is OK if the actual value is at least 850-900 mg/h at 3000 rpm.
Yes, my vag.com is from Ross tech, so I am going to mess around to see if I can see the graph.If you have vag com from ross tech it comes with vag scope, a program that puts the logs into graph format.
It's fine if you want to check the timing, it's not good for much else. There are a lot of other functions that the real "ross tech" vag com can do, I recommend that.Is the ebay vag-com any good? How come it's much cheaper?
