what's your fuel range?

Did you disconnect the battery?  The trip gets reset whenever the battery is disconnected, even with ignition turned off there is a live connection to the clocks to keep the trip meter memory working

Yeah I did Jules-C, I disconnected it when I put my optimise lleads on the battery, knew I'd find out eventually,  think all is well now, taking note that I don't disconnect the battery this next try lol
