I was going to write a detailed reply to this question, then I checked back and realized that I already did. Page 1 of this thread, post #8.

My primary use of my SG is the short trip display as discussed above. My secondary use is the instantaneous MPG display in conjunction with the analog vacuum gauge: http://ecomodder.com/forum/showthrea...tml#post508414 (post #37). I also display coolant temperature because I have a grille block, but that is not important because my truck came with a real temperature gauge.

Accuracy of MPG gauges is not important because they are only used for comparisons. Actual MPG is always calculated from fuel used and miles driven.
