i would like to try the second map feature of the MJ.
i know i have to fit a switch but where do you put the second map please.

many thanks

It's very simple - when you put the switch in one position the config software 'talks' to that map - put it in the other positon and the software talks to that map.

I have 2 maps saved for my car (for regular & unleaded petrol) and I load them in separately, swtting the switch as necessary.
