I was reading through my (old) AFC book yesterday and was looking at the decel settings. There is a throttle setting, a Ne1 setting and Ne2 setting. Before my Ne 1 & 2 settings were really low, around 2%. So I started raising the all 3 setting points. The more I raised it, the better the car drove. I ended up puting the throttle at around 18% and both "Ne" settings around 19%. Now there isn't near as much fluttering at part throttle from the greddy type s with both springs in. It's alot harder to make the car stall when moving up 3ft in traffic. If you play around with these setting make sure the "Thr" % is lower than the "Ne2" % or it won't work. Happing driving.
