OK, after going to 4.10's my speedo is way off, and I am sure my odometer is probably off, too. What are one's options regarding getting these recalibrated and at what cost?

Thanks,

Tom

Isn't the speedo fixed with a new gear (little plastic one)?

Buy a VDO and put that in there instead. I dunno about disco specific # but the one I have planned for the 110 is tuneable quite easily. Your other option is to change the gears in the T-box where it drives the speedo. Now since you have a 97 it may be all electric but you could concievably retofit an earlier speedo and pick the gears of your choice which should get you close.

PS or you could just use the GPS for the speedo
PPS 4.10s and 32s should be about correct, of course yours was probably fast in the first place.

Hey Tom,

I don't believe that we can change the speedo pick-ip gear, as the Disco doesn't use one, it uses inputs from the Engine computer, doesn't it? I don't remember what year they made the switch. Anyhow, since we have electronic speedometers, check out this product:

"SUPERLIFT ANNOUNCES THE RELEASE OF THE REVOLUTIONARY TRUSPEED SPEED SIGNAL CALIBRATOR
WEST MONROE, LA - A speed sensor calibrator has finally arrived that addresses the needs of any computer-controlled vehicle running larger (or smaller) diameter tires: The Superlift TruSpeed speed sensor calibrator. The TruSpeed works with any electronic speedometer and hooks up in line with the speed sensor located on the transmission or transfer case of the vehicle. The TruSpeed alters the speed signal at its source, so speedometer reading, ABS function, and transmission shift points are all corrected to work with any non-stock tire diameter. A simple four-wire hookup is all it takes to install the TruSpeed, and comprehensive installation instructions make calibration an easy one-man operation. It not only corrects the speedometer reading to within 1 percent, it can be recalibrated an infinite number of times if future gear ratio and / or tire changes are made to the vehicle. In addition, the TruSpeed can be programmed for two different height settings for those who make seasonal tire changes or those who frequently run two different-height sets of tires on the vehicle (i.e. "street" and "show" tires). The TruSpeed will soon be available for all domestic and import cars, trucks, and vans equipped with an electronic speedometer. For more information, contact your nearest Superlift dealer or call the company's sales / tech line at 800/551-495"

Ron, what the heck is a VDO?

I like what superlift has to say about the speedo, as I have two sets of tires. I am probably going to get a GPS anyway, so that will work for the speedo problem, but the anal retentive side of me would like to have the speedo be accurate.

Any other options for the odometer? It would be nice to calculate actual mileage. I guess the worse case scenario is that I do service at earlier intervals....

Correct the Speedo and you correct the Odometer Tom...

VDO is a manufacturer of speedometers.

Some rover places sell them. Popular among the vinyl seat crowd (d90s)

Scott - Gotcha. I wonder what the chances are of Superlift making a rover product.

They flew me in for this week-long class, but didn't pay for a rental.... sheesh! Gov't will pay $500 for hammers, but won't give a guy even an economy rental...

Not a bad town, though, much better than I thought it'd be - I had nasty mental images, but it's a LOT cleaner that expected.... still, it's a big city, nonetheless - and I like small towns and backwoods... ;)
