OK...I talked to the Dakota Digital people, and the Universal Signal Calibrator (SGI-5) WILL WORK on ABS-equipped Xterras. They clairifed what was posted on their web site, and the SGI-5 chip just can't be used to correct signals actually being sent to the ABS computer. :rolleyes:
I'm gonna go ahead and order one of these and see how well it works out on the Xterra. I'll post results and how they compare to my GPS reading.
Let me know if anyone is interested in results!!
