Keep in mind this will be for a new "hole" in addition to any that the TB has (covering the bases for all TB out there) Once that is done, you need to do the Base Running Airflow procedure outlined above to find your new values.

Does anyone see a "reset TPMS" prompt anywhere in the menus/sub menus? If you get some idle surge, chances are you may have too much timing in there (if your base running airflows are tuned and your fueling is good). Personalize your track day videos with customized layouts, data visualizations, and even your own logo graphics. The data will be pasted into the Base Running Airflow table (HPT > Engine > Idle > Idle Airflow > Base Running Airflow) for both P/N and In-Gear. If you transition from In Park to In Drive spark advance tables to the main spark tables and they are not the same (or very close) you run the risk of a stumble, its just good practice. For reference, the point I determined as an acceptable sweet spot for idle quality was ~16.3 from the start point of 14.7 (same as the guy that coined this method).
