notice 2. Lo-Thrtl : 800rpm +50% this should be 0%
at 38 seconds in the video you see 7200rpm set to zero. hit the left arrow key and it will go through all the rpm set points. make sure they are all 0. then do the same for the high throttle points.
The SAFC has rpm correction points for high throttle( when the throttle is 50% or more (if you set hight throttle point at 50%)
It has low throttle correction points for when it is less than 20% open (if your low throttle point is set to 20%)
Make sure all rpm points are set to 0%.
