In this webinar we will be looking at how the GM E38 PCM deals with controlling fuel in open loop (full throttle). We will be discussing and explaining the Power Enrichment tables, what Equivalence Ratio is, and how to apply your desired air fuel ratio targets. We will then look at how to correct any remaining error to accurately achieve these targets.

This webinar will be performed using a 2013 HSV R8 Clubsport fitted with a 6.2 litre GM LS3 and we will be using the HP Tuners reflashing package.
