Advancing R34 Odometer?

[Danox]

I may pick up a Nismo cluster for my USA-landed R34. In the USA, my car was converted to display miles instead of kilometers both on the speed gauge and the odometer, and reads a certain number of miles on the display. The imported Nismo cluster would read zero, and to maintain legal handling, I'd have to do one of three things -- have a repair shop put a federal sticker on the door indicating the milage reset ($$$), find a shop that can advance the Nismo cluster for me ($$$) or find a way to advance the R34 cluster (hopefully free).

I thought if I powered it, and then fed in an appropriate speed signal, I would just have to wait until the car reached the right number of km on the display, then disconnect. I believe a signal generator could do this. I have heard from other Nissan owners that the electronic gauges on various Silvia's use 6V Peak to Peak square wave for speed, and the higher the frequency, the faster the speed. I can procure a signal generator and feed in the speedo info, putting it up to 300km/h, I'd just leave it on for a half of a day (this car only has 4,731kms on it, believe it or not) and pull it when it reaches the desired kms.

I want to try, but I don't want to make an error that I can't clear by feeding a bad signal. Has anyone attempted this, or can anyone confirm the R34's speedo signal specification?
