UG fuel cutoff in engine braking?

[Vekke]

Hi,

I am calibrating my customers UG and havent been able to reach fuel cutoff mode in the UG. How you should do it? I have tried to set the figure you adjust to 0 or few other values without any luck.

Car is a diesel Smart with automatic transmission...

Maybe the car never shuts off fuel to avoid stalling the automatic?

I think you have to set the value to 7.5 times the engine size, I think it says it on the UG, if not it's on the website. It also says on the website that it will work for your car if it goes to closed-loop mode. But that makes me think that the UG "tells" the car to cut the fuel off to the engine... idk how it works, UG website might say though, the manual is really helpful.
