Trip Computer MPG

I've got almost 80k on my 2007 MDX Tech Sport and have given up telling the dealer that the trip computer overstates the mpg. It seems like it should be a pretty easy calculation with the ECU and other stuff to calculate the mpg exactly (how many miles divided by how much gas consumed, duh) but I found my spreadsheet method infinitely more reliable. I know Honda had a recall awhile back for overstating mileage on the odometer and hence ending warranties early. Could this be part of that problem (i.e., correcting the odometer but not the trip computer) or is my tinfoil helmet too tight?

Something is too tight ...
Federal Odometer Act

From Wikipedia, the free encyclopedia

Jump to: navigation, search

This article is an orphan, as few or no other articles link to it. Please introduce links to this page from related articles; suggestions may be available. (March 2010)The Federal Odometer Act, passed in 1972, modified the United States Code to prohibit tampering with a motor vehicle's odometer and to provide safeguards to protect purchasers in the sale of motor vehicles with altered or reset odometers.[1]
The Act provides definitions and civil and criminal penalties for odometer fraud.
[edit] Interpretations

The Act was intended to protect consumers buying used vehicles from odometer fraud, typically used against sellers who intentionally tamper with an odometer to misrepresent the actual miles an automobile has been driven. However, in 2004 and 2006 there were two class action lawsuits filed that allege American Honda Motor Co Inc and two of its suppliers violated the Federal Odometer Act because the odometers in approximately 6,000,000 Honda and Acura vehicles overstated the actual mileage by 2% to 4%[2] even though the Act contains no provisions for odometer accuracy. Subsequently, Honda changed the tolerance of its odometers from -1%/+3.75% to ±2.5%.[3]
