Maybe its a tune from back in the day before ecuflash? I know this has been discussed add-nausium. Remember it wasn't so long ago when we were not very lucky to have unraveled all of the secrets of the stock ECU 22 counts of knock is inexcusable though. The owner obviously hasn't checked up on their tune in WAY too long. Periodic logging should be part of regular maintenance. This is why tephra's KnockCEL is awesome, you'd know if the car was knocking all the time w/o even hooking up a logger.

That's the first time I've ever seen a "20" in the AFR map. I hope I never see that again. That previous tune was absolutely ridiculous. Plus, I'm not sure what loads they were hitting/dropping down to, but, that ignition map was way past MBT- especially for pump gas.
Even when I first started tuning, my maps never looked like that.
Kudos to TTP for rectifying the situation. I'm impressed the block/head lasted that long with that much knock occurring.

In Al (dynoflash) defense, this tune is probably very old and was probably done with Techtom (old flashing software), which is done it all hex and very, very complicated, compared to ECUflash.
Still the tune is unacceptable and never should have been put on anyones car.
