Speedometer recalibration: is it possible?

Autotrans offer a recalibrator and I currently have one for testing - is there sufficient interest for this device? It costs approximately $150 and must be spliced into the harness under the vehicle.

The Web site is here:

Actually, I read up on this and I am a little interested. According to their Web site, the ABS system uses speed calculations to determine proper behavior. Although it isn't mentioned, I imagine the speed calculations also affect airbag deployment parameters. My new tires will alter the VX's speed calculation by 2.5% -- that's probably pretty significant when you're talking about the delicate matrix of conditions required to trigger airbag deployment. I wouldn't want to take a risk with impairing the bag's trigger characteristics.

So... let me know how your testing goes and I might pick one up from you if they aren't too difficult to install or have an unadvertised trade-off.
