That is encouraging. I am confident of DFCO as I have using it extensively on trips and the ultragauge has matched the calculations from fillups. However the fillup last night after using engine off coasting for the first time did not match. Either the pump is way off, which is possible as it was pumping very fast, and is going to be inspected by the end of the week, or else the injectors not only didn't go off but increased.
If the latter is the case, then I'm going to stick with P&D or engine on coasting, as the mpg result would have been much the same, and been accurate. I will know the pump results in a couple of days.
