I have the YellowBox and it works great. My speedo is corrected just fine.

OLT- the Yellowbox fixed this problem in no time- nothing complicated at all. I didn't need to do anything to the "obd2 system" either. Power, ground, and cutting the speedo wire directly at the speedo sensor on the tranny.

scroll toward the end of the thread and you'll see some useful info about correcting the speedo with the YellowBox.

Hope this helps

how much are those things.
you could probably build one yourself.
Its probably just a pulse width modulator.
sounds complicated, but one of the first things we built back in school.
