Sorry not meaning to thread jack but can the Scan Gauge change the tire size in the computer to correct the Odometer, miles per gallon, etc? Thanks.
if it works like most other cars the ODO get's it's signal from the speedo so if one is correct so is the other.
Also most Autoparts stores will scan your car FREE..
VIP, Autozone, Napa, Advanced, Pepboys, etc... just ask they'll plug in and read your code and wont charge you a dime...
in my state I need to be CEL free for the annual state inspection. Had the EGR go on me just one week before my inspection (d'oh) I tried cleaning it twice and it would be CEL free for a day or two and then it would come back so I just bit the bullet and bought a new one on ebay (~100 after searching for a while most new ones go for 150-200)... came with a new gasket and everything and the VX is much happier now.
I've been using an Actron scanner from Sears Like this one for several years. Cost me about $150, but I needed something for my Lincoln, S2000, and VX. Not very fancy, but gets the job done.

i have my scangauge flush mounted in the ecu cover of the vx.. still can pull it out fairly easily, i ordered a second cable for it (scangauge separates from its cord via an RJ-45 connector) so i leave the one behind the dash and the other in the glove box so that i can pull it out and test other cars
as far as i know the speedometer reading is a mechanical thing you need to change the gears in the gauge cluster to correct it.. bbut you can get an accurate reading on the scangauge of your speed by putting in your tire size change factor
