The MTX works fine and uses the same Innovate to Flashscan cable as the LM2? Given how the Innovate serial protocol works, 2 MTX gauges in series must have the same data stream as a dual channel LM2 so Flashscan should log both channels with no problem. As I've been let to understand things, never tried it, but sold a number of people single MTX gaugess to connect to Flashscan and never had a complaint.
