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.
