OK so throttle response really requires us to get our transient or acceleration enrichment tuning spot on. That accounts for how much fuel sticks to the walls as the throttle opens quickly or when the engine is cold and the fuel doesn't vaporize well. Generally speaking Transient fueling makes changes in fueling at the tip in/ tip out which gives the fuel required when there is a rapid throttle change in order to keep the engine running smooth. - Transient enrichment, accel enrichment or tip in enrichment as it's often referred to is required to ensure stable control over the air fuel ratio as the throttle is either opened or closed rapidly. Idle airflow plays a large role in this. Use the config file in the sticky up top and log from a cold start. It is important to give the following definition: The equation describing inferred MAP is that of a straight line equation in the form of Y = mX + b where m = slope of MAP vs aircharge, X = calculated aircharge and b - MAP at zero aircharge. 3/6L80e, not as slow but still heavy.
