The PLX MULTI-GAUGE with OBDII has taken the automotive display to a whole new level. Now not only can you daisy chain our Sensor Modules but you also have access to all data on your ECU. This allows you to view all parameters of your vehicle and also act as a scan tool to check and clear engine codes when necessary. Unlike other automotive displays on the market where the user has no choice but to view the data presented in one form PLX has designed the MULTI-GAUGE so that you can set and change your viewing preferences at any time. All styles have their unique advantages and you should not be limited to one option.
