I got a PT61 turbo on my IS300. I was doing some street tuning and logged all my sensors. I noticed at around 170 KPa from 4000 RPM and up, my knock sensors detected knock and retarded my timing about 2 degrees in some instances and 1 degree on others (depended on how high the sensor read). I'm wondering if I should let the TEC3 retard the timing or if I should just retard it through my calibration file. If I let the TEC3 retard it, will I cause any long term problems? Here's my timing table, any feedback would be great.
