i have that display in my blazer. but it has hardly ever worked. and its been to cold for me chase the problem down. im thinking it may just be the entire display itself is fubar.

but i like that idea. having to glance up or having that green glow out of the corner of your eye is a distraction to driving at night.

i believe that in order for it to display the instant mpg, it needs the fuel level, amount of fuel being delivered by the injectors (pulse width and fuel pressure) being sent to the lil ohc display logic. it then calculates the fuel consumption and and tps reading to display as instant. and for the average it should just do an average formula to display it correctly.for the range it much calculate the average mpg to how many gallons are left in the tank. the avg speed looks as if will just calculate from the vss. that is 4000ppm.
