Various logs, Comments welcome

[Phil]

Just been out on the A5 doing some logging, comments welcome on the plots. These are for fault finding in the hope I can discover whats causing my low MPG at the moment.

The car is a Jabba remapped Octavia 1.8T which has the K03S turbo

Can you post the actual csv files please?

 

[Daz_gibbo]

yeah... im sure your boosting more than 2 Psi..

 

[Jonzy]

And whats your definition of low mpg? That graph looks to be mbar rather than psi.

 

[Phil]

Yep, my mistake - the boost chart should be in bar and not PSI I diddnt deduct the atmospheric pressure either - do I need to do that?

 

[Phil]

The results are here in excel format:

MAF figures look a little low for a K03s, my Stage 2 Ibiza on a K03 is pulling 160s on a standard airbox and dirty paper filter but that wouldnt account for low mpg.

Boost seems ok, looks like quite a conservative map peaking at 17psi and holding to around 11. Charge temps also seem fine.

Can you log your o2 sensors please? Blocks 32/33 (i think)
