If your vehicle does not have an OBDII port, and you want to be able to record more data channels from your vehicle, your only option is to use a hardwired solution.
The RaceCapture/Pro Mk 3 we carry is just such a solution. It allows you to hardwire your inputs into the device which then provides the data wirelessly to your mobile device and our apps. The extra benefit is that it also includes a GPS device so you do not have to manage yet another device.
