Hey guys so ive finally started doing some basic tuning on my 2018 GT. I know this may seem like a stupid question but I wanted to clarify. Negative knock on the scanner means the ECU is adding additional spark or pulling it. I know this sounds contradictory but an online webinar I recently watched show that then the KR went Negative they were saying to ADD spark back in.!!
Hope this makes sense. Ive attached a log file for reference. As you can see at some light throttle accel (< .5 Load) im seeing upto -6 Knock. and same as the WOT pull upto -4.
Any advice on this.
Cheers Allen
