1. Describe the problem you are having in detail:
What happens is as i accelerate truck goes through gears fine but once past 45 truck wants to go faster and i am hardly pressing pedal. I can get up to 65 and when i want to ease off the throttle I have no room to back off to go slower it just drops to idle causing bucking if i step back on pedal to keep up my speed. I never had this problem running on diesel or veg. I have a totally separate fuel system and filters for veg plus separate returns. Since this is my first fly by wire rig it's a mystery to me. New water temp sensors.
Thanks
