Holley EFI control interface for RTX and VHX gauge clusters

This is the add on module you need for both RTX and VHX series gauge clusters to pull the majority of info from the Holley Dominator, HP, Terminator and Sniper ECUs to display engine vitals on your Dakota Digital dash. You will need this for any Dakota Digital gauge cluster we sell, to properly display all the extra sensors and monitors available that run into the Holley ECU. This will allow you to easily display Fuel Pressure, O2 sensor AFR reading, MAP, IAT and a number of other data points you may be using with the Holley ECU for data.
