Very Nice!
For the RacePak there is a formula to input into the software to program the IQ3 to get a speedo signal from the transmission if it has an electronic output. You have to wire the electronic output on the trans to a USM box and then input a value into the software. The formula for the value or "factor" as the RacePak guys call it is:
tire height x 3.14 ÷ 12 ÷ 5280 ÷ rear gear ratio x 60

This is handy to have because the GPS speedo does not always connect when you need it or if you are in cities or tunnels

The IQ3 will at times freeze up but I just reset mine on and off and it works fine
