I bought this for my '68 Mustang. This works very well. It tracks PSI and temperature. I set a very cold starting temperature and got alarms shortly after starting for a test drive. I reset the temporary settings and everything has been great so far. The PSI settings are very accurate and the device was very easy to communicate with the bus transmitters. The entire setup took about 30 minutes and the head unit is easy to read even for my "old" eyes!
