Phantom knock, or not?
Posted: Mon Dec 09, 2019 11:22 am
Hi all
I'm hoping for some help from the pros on here!
Car: 2002 UKDM CTR, K20A2, Rotrex C30-94, Kpro4.
Car has been supercharged for 3.5 years, no issues.
Recently removed gearbox to fit an LSD, replaced starter, broke the knock sensor. Replaced with a cheap aftermarket one, car instantly started showing knock (has never had this issue before) replaced that with a Ktuned knock sensor, same issue.
The only other thing we changed was a Powerflex gearbox mount insert which has now been removed = no change.
Tuner lives quite a distance away, has adjusted map (see modified kal) to remove timing, still showing knock. He is convinced it's phantom, I can't work out where it' suddenly appeared from.
Any help/advice appreciated. I am losing my marbles chasing this around! Happy to supply anything further needed.
Original Kal + Knock knock log
Modified Kal + knock knock pt2.
Sorry for the massive datalogs!
Thanks
