I was able to log Knock retard with Evoscan Beta 2.6 on an Evo X. I confirmed it is knock retard because everytime it happens the timing gets pulled. I also logged timing advance, rpm, TPS and IPW and IDC. But I do not know if IPW and IDC are accurate. I know the rest are accurate because I compared the logs from Evoscan to the logs from PCMScan.
From now own, I will use Evoscan in conjunction with PCMScan until Evoscan becomes fully functional. I will do the tuning with PCMScan and will check for knock with Evoscan. Not that I need it, because the timing in the attached log was done w/o the aide of knock retard by looking at the timing curve and adjusting timing when it gets pulled. You will note that the timing was pulled 1-2 degrees at most even though I tuned that car w/o Evoscan.
It does bring peace of mind to have knock retard to back up the tuning of the timing curve.
