A few days ago, it got warm enough to where I wanted to go to a car meet. I took the car (of course) and ran logs on the way out. I also ran logs today when driving to a doctor’s appointment. Well…I saw lots of knock…WTF. The only thing I can think of that’s causing it is bad gas (I filled up on Friday…those logs were partially clear). Thinking on it now, it could also be the fact that the weather is warmer…warm enough to have heat-soak (which could contribute to knock on the OTS Stage 1 tune).
I got scared enough to where I unmarried the AP…it may stay unmarried until I’m ready for a protune. While the DAM was still 1.0, the knock was very prevalent (finke knock learn, actually, which pulled timing quite a bit in some instances) . I’ll see if I can post the logs.
EDIT – The logs are here.
UPDATE – I think this might have been a combination of bad gas and the fact that the engine was loaded and in top gear. No, I wasn’t lugging the engine, nor was I boosting significantly in 6th, but I was in 6th with light load and running the AC, which the 93-octane Stage 1 OTS tune doesn’t like. When I went to the Stage 1 91-octane OTS tune, it stopped. I’m still running the 91-octane Stage 1 tune.
