Vcds Log Help Please - Maf Log.

[Adam1]

Could some one take a look at this graph and tell me if the maf looks like its playing up or not? Took me ages to work out what to do and how to do it and the graphs mean nothing to me now!

 

Thanks

Looks ok to me!

I would say inconclusive you need to do the log file with the engine pulling hard at around 3000rpm and hold.

 

So ideally have some weight in the car and you need a long uphill gradient where you can accelerate 100% throttle (flat out) and hold it as long as possible

Ok thanks. Shall give it a go as its lacking power on hills.

Plot the percentage dmap as a second y axis. I tried to post the graph I created for my gal that showed the turbo overboost then going into limp mode last night but it failed. No doubt I'll need to host it somewhere then link to it. My understanding is that the maf usually fails and gives a constant reading, hence my comment that it looked ok!
