yes there is. In the manual it explains that run of the mill lambda sensors are variable and produced by several different manufacturers. I think they mean that the voltage produced for a given fuel/air mix varies between bikes. If a bike is fitted with a wide band sensor (eg for racing) then the Rapidbike module displays actual ratios.Mike, thanks for the update. Again, very much appreciate the updates you post. I have no answers but the extra fuel use is quite high I think. There's some crappy weather coming so I might finally install the evo on my AT but the more I think it over the more I doubt things will really improve but then again...who knows. Kinda regret buying it....impulsebuyingaddiction...
Is there a good reason the EVO doesn't show true fuel/air mix and throws out just numbers?
They also say that lambda sensors are not very reliable at the bottom end where I am trying to sort things out. By that I think they mean that the voltages per fuel/air ratio could be inconsistent from moment to moment on a ride. This may explain my results above and would be pretty disappointing (but not Rapidbike's fault).
