    One more question for the team - what is the difference between startup friction airflow correction and start up airflow correction?

    The Start-Up Airflow Correction does not decay. It is 'permanent' in that it is always added at Start-Up. Best to leave alone.

    The Start-Up Friction Airflow Correction temporarily adds air to Start-up. It then slowly decays. Thats the one that will really help you. It will give you the additional air you might need for start-up, but then it decays..Perfect for cams and hot/cold starts..

    also set B4606 and B4607 to 1 second, this will reduce the amount of time it is in that mode, with enough airflow programmed it start right up no bog (mine did this forever but its pretty well solved now)
