Hi Guys,
My 2012 N55 has been having unsettling timing corrections over the course of the last year, and it's making me nervous to get on the throttle! Sometimes I've seen up to -7 deg on a cylinder!
Recently: Fresh gas, new spark plugs, new coils, fluids... didn't fix anything. Uninstalled MHD to check if it's the tune, but that's also not the problem.
Here are some logs of a pull w/ Fresh 93 oct and the STOCK tune. Car has a 6.5" intercooler, chargepipe, and catless DP. You can see timing corrections of -6 on just cylinder 3 in the 1st log, but multiple -3 in the 2nd. Having the car tuned with MHD makes them worse.
Does anything stand out to you guys from these logs? Ideas?
