S13 Speed Sensor Calibration

[KiLLeR2001]

I was thinking a little earlier today. All non-SE S13 wheels received 195/60/15 series tires. So I would assume that the stock speed sensor was calibrated for this size. Now vehicles equipped with the factory SE alloy wheels received 205/60/15 series tires, which will be about a 2% difference (too slow). It's to my understanding that all the s13 speed sensors are the same, so cars equipped with the SE wheels, are technically not recording mileage accurately...

To put this in perspective, if the speedo reads 60mph, you are actually traveling 61.2mph. If the car has a total of 100,000 miles recorded on the odometer, the car actually traveled 102,000 miles.

I know this is pretty much irrelevant information at this point since everyone has switched wheels and tires around a million times by now... But its interesting to think about. If anyone has any more information to add to this that would be great.
