Currently using it with Vevor ZM2003 but I removed everything as its a direct replacement for my Espar D2 in my semi truck. Sofar seams to work good.. Except the Altitude doesn't change- always 0 no matter with plateau on or off. Things I would like to see in the app... Decimal points on all the settings like voltage and altitude.. I'm assuming that if there's an error that it would show up top where the status is under the heater name but if not - definitely want to see it there. Also would like to know more about how to use plateau mode? As a truck driver, I'm always at a different elevation. Does it only do fuel correction when its activated? Should I leave it always active? My unit has the CO detection option. Would be also nice to see the current readout on the app..
