Thank's for the reply, I did not yet buy the odb2 module that plugs in right behind the dash. My friend bought a lot of these so I got one decently priced. I will be orderign the odb2 soon though and it is plug and play.
I still rather connect the RPM via the wire instead of odb2 based on refresh rates.... I will update again in a few days when I have time to finish things up. The GPS on this isn't the greatest, takes a few minutes to acquire a signal and it's best to have it outside the car..... might stick it on the hatch somewhere (magnetic) or just open the window and put it on the roof while at the track...
