Very strange KR
I noticed after I calibrated my PCM to use the 2Bar MAP sensor from the 1Bar that I got some KR. I'm not sure if this was merely coincidence or if its actually KR.
This morning on my way to work I decided to scan. I had the factory tables for the 2005 GTP on there. Keep in mind that its irrelevant which table I'm using as the location on the spark map where I got some KR was virtually the same between a 2000 GTP and 2005 GTP.
I noticed this was under 53% throttle. Engine temp 107 degrees, air intake temp 37 degrees. Certainly not KR inducing conditions. O2 was reading 980mv, which is way on the rich side. I was going 27mph when I gradually accelerated, keeping the car in a low gear. I did not go wide open throttle, only 53% throttle, yet got 7.8 degrees of KR!!!
Now, upon acceleration from a stop, I've noticed some vibration which I suspect is a bad engine mount. I'm going to be replacing that soon, but for those of you who have some tuning experience, is it at all normal to get that kind of KR under those conditions? Or is it more likely that its false KR...
After that KR reading, I went wide open throttle about another 5 times from a dead stop and got absolutely no KR in the higher airmass values of the table. It was only at half throttle that I got that KR reading...
