E40 idle tuning with cam

[Gelf VXR]

Here are the results of my logs for deriving desired idle airflow settings.

My calibrations are set to 800rpm idle and 13* idle spark @ stoich

I tried adjusing the injector timing event and added / subracted to base desired airflow in neutral.

I logged with calibrated MAF only, dynamic fueling / fuel trims disabled (set to400rpm)


I think I came very close to ideal with - 10% of my base desired airflow, - 11% will probably do it.

I'm going to try 750rpm idle as thats what the cam is advertised to be able to do, to lower fuel consumption at idle.

My MAF is still a fraction out fueling slightly rich, I wont slightly lean for emmisions

I'm probably going to go with 3* to 5* advance on my injector timing on the ECT calibration and leave it there, (the difference between ICL of stock and new cam).
