Can an SCC be recalibrated for tire size?

I got around to installing an SCC on the weekend that I bought on eBay. It's for a '90-93 MY but is still a plug and play in my '89 with the 2nd 8-pin plug that was buried behind the radio (and which I learned about here in the "archives" -- thanks!). Anyone know if the SCC can be recalibrated -- it would be nice since my speedo is for 15" and I'm using 16".

As long as you are not changing the overall size of the wheel/tyre (which you shouldn't be) then no recalibration should be necessary. Stock 15" is 195/65/15, giving an overall dia of 634mm. The stock size for 16" is normally 205/55/16, giving an overall dia of 632 mm.
