I bought this a few years back for my race car, but it never really got any use. It comes with the wiring loom (very easy to install), main unit, and speed sensor.
I dont have the temperature sensors it came with, but it can be calirated to work with most standard sensors. It also has the CD with the software. The only thing that is missing is the usb connector wire to attach it to a laptop for setting up parameters. Although from what i remember, you dont actually need to plug it in, all settings can be done direct on the dash. I did contact ETB about a replacement, i recall it being around PS30
