Low RPM/Partial throttle knock detection (new issue)

Post by dglidden »

Hey all

My car sat for a month after my last HPDE event. I went to drive it yesterday and am now getting about +17 knock detects at low rpm when I give it partial throttle. At the last HPDE I had to change my knock sensor because the connector broke off the sensor. I used an ACDelco from a local autozone. The car ran fine the rest of the weekend and drive home. I'm attaching a short data log showing the symptom as well as my configuration. Any help/suggestions would be appreciated.

Negative. I dont hear any audible knock. Additionally this is only at low RPM if I give more throttle and hold it knock count does not increase. Its only when starting to give it throttle.

Have you tried reducing the timing in the areas it is knocking?

No, I wasnt sure if thats the proper next step or not. This is the same tune I've run for awhile so it'd be weird to have to change the timing no?

I have an appointment with my tuner to take it to him on Tuesday

Then I would wait to see what the tuner has to say.
