Ok, thanks for confirming that.
Engine 1.5 is being replaced with the much more powerful Engine Prime. Even though the MCX8000 isnt a Prime unit, there is new firmware for the MCX (Currently in Public Beta Stages), which will allow the MCX to read Engine Prime Databases, as well as adding many new features to the MCX itself.
Users can still join the Public Beta Testing for the next few days, and participate in the remainder of the testing, which, when complete, will result in Firmware 2.0 being released for the MCX8000.
Why not download Engine Prime now to get acquainted with it.
