Or will it perform/present The brand new parameters once I plug my mvpi2 machine in to the obd port and turn on my scanner and so forth?
The moment That is performed, Allow the engine cool all the way down to as chilly as is possible and re-accomplish the idle-airflow.cfg config I connected above because now your base davie4 software jogging airflow desires are distinctive.

Spark progress good tuning - Make use of the VCM controls when idling to regulate the timing till you see very good MAP (extra vacuum). I turned off adaptive spark using the bi-directional controls Along with the scanner (Spark Idle) so I'd a steady, flat timing line and could essentially check if there was MAP changes. Make this happen by going to the VCM bi-directional controls and disable the Adaptive Spark Handle (termed “Spark Idle” under the fuel and spark tab) by truly clicking the “ON” button. Click on again into the “chart Screen” and notice your timing line…it ought to be a gentle flat line rather than a observed tooth sample, Otherwise, you didn’t disable the Adaptive Spark Management.
