Re: Increased MPG
i'm still trying to see how it works. it seems to me that it would be rasing the air fuel ratio. so basically leaning it out. which is bad for heavy loads. why not just tune it to a higher afr to start with if that the case. in hpt there is a tab called "lean cruise" it leans out the afr when at a steady cruise with a light load on the engine. but in america its illegal do to it raising the afr which raises emmissions. so if this is doing the same thing wouldn't it be illegal as far as emmisions is concerned? anyway in alstralia they use the lean cruise thats why we have it in our hptuners program. susposely it doesn't work in american cars even if you set all the setting for a stock holden car.
