I drove the 2000 TDI NB with SGII yesterday, it appears as though the SGII is accurate(based on fillups on a regular commute) and some quick quasi experimentation makes it appear as though it is off in the opposite direction than mine (that is lower indicated consumption on high flow rates and higher indicated consumption at low flow rates). Economy stays rather near 30mpg from 55mph to 82mph, we all know that is incorrect.


Differances in her car from mine.

1) Auto
2) 11 mm pump head (autos have 11mm 5 speeds had 10 mm)
3) lower mileage she is around 120,000 miles I'm around 175,000
4) More worn engine, hers had the wrong oil for the majority of its life, cam is worn down, and I suspect the rest of the engine is the same
5) I THINK more Aero drag (bug Vs Golf), (also missing suspension dams, under tray,an added spoiler, and wind deflectors on windows)
6) Larger, non Low Rolling resistance tires
7) Timing belt done by stab and pray (unknown pump timing)


Any thoughts?
Encourages me that some cars read one way and others read the other . . . . .


This makes me finally realize why she keeps telling me that she might as well drive 80; because her milage is basically the same, her scangauge has been giving her false information!!
