using vag com to log misfires

[sambb]

In VCDS the misfire block will switch to "enabled" at idle and log misfires if they exist. I want to look for misfires in a power run, but in these blocks it will switch to "disabled" once the revs move away from idle. How can I look for misfires when underway?

I know it's logged in the nefmoto ME7 Logger...

I haven't checked to log it on VCDS... There's a knock block, I'd have assumed that would be a counter of such events, though could be wrong. Mine read zero so kept clicking through.

I'm setting up the boost trigger for my water injection and it seems to be tolerating having the water start quite early, but I just want to be able to check if I'm causing quenching style misfires anywhere. Come to think of it I don't know how it knows its misfired - does it go rich for a sec on the o2 sensor or does it know if the coil hasn't discharged. Not sure.

Water kicks in about 5psi on my s3 and it runs flat out. Never had it bog or hesitate.

Oh ok that's good to know. Aquamist seemed to recommend setting it to trigger at the pre modded OEM max boost setting. I started at 12psi and have been going down bit by bit with no detrimental feeling. Wasn't sure how far I could go but based on what you said i'll keep dropping and see.
Its aquamists smallest rated nozzle, the 0.4mm "A" jet which at 100psi pushes nearly 50cc/min. That's at 12v on the chart so it might be more at 13+ driving volts though, but yeah I doubt it'll bog. I did some back to back logs and its nearly 10 degrees cooler at the AIT (injecting 3 inches up from the MAP sensor). Over such a short distance that seemed like a pretty good drop and it must still be cooling long after that because the plenum temp is lower than the AIT temp suggests it should be. I got peak AIT temps of 42 degrees @ 24 degrees ambient, plays 51 degrees with no WI with a stock intercooler. AIT starting temps of the pulls were low 30's degrees. I still get a tiny bit of timing pull when I tip back into it on a 2nd to 3rd gear change but where that used to be 1.5-4 degrees for maybe 4 lines, its now 0.8-3 degrees for only two lines, so its helped with that lean spot already. The maxed out MAF reading wasn't any different but when 3rd gear gets into stride you can really feel it.
