Calc.VET: correcting MAF and calculating VE (in single log)

Hi ET, something happened to your screenshot, can you please post it again.

Uploaded a new screenshot in the post above.

Here is the complete log.
The tune is the stock tune from the car except the changes in the summary notes.

Post your tune file.

Looks like you're running lean, can you hear it knocking...?

Yes.. Its way leaner than I would like. Except when in PE mode. Cant hear the ping, but I see knock on the logs.

Here

Used the ltftben from the first log and made adjustments to the maf calibration. logs now show close to zero ltft :) No more knock retard :)

Tok another drive/log and did some adjustments to main ve. Probably need some more logging/smoothing. But does it look reasonable ?

VE looks quite good (did you use LTFTBEN...? did you disable the MAF when adjusting the VE)...?


I don't know how high your engine revs, but for safety bump up the VE table from 5200 thru to 6400 or 6800 rpm.

Thank you :cheers:

I followed the Calc VET tutorial to calculate the VE table. Used "Calculated VE, BEN corrected (g*K/kPa)" so the VE is calculated with data from the MAF ?

My next step is to disable MAF and se how the engine would run on the VE table. But due to some unexpected snow I will need to wait for the roads to dry up.

Yes, VE is calculated with corrected MAF data.

Ok, no worries, that's a lot of snow, take your time, keep safe.

Will this method work for any controller ? Sorry if it's been answered in the thread. I have a 2009 CTSV E67
