Your talking about two different things.
The mpem will count from day one. You can only reset the maintenance and rental house. Total hours can't be AFIK. Programer just won't let you alter that field.
The Info center is completely seperate. I has its own counter and in theory should be the same as the MPEM or it will have more than the mpem. There is no reset that I can find. Even looking at the IC I think the only way to do it is to re-flash the original program onto it or add a switch for reset in the conde.
Actually the best thing to do is for someone to rip apart the info center and use an arduino to drive the stock display. Then just write the code similar to the stock one in function. Shouldn't be too hard, just time consuming...
I might be nuts but I average 100 hours per season at least
And that's on a Canadian season lol
Haven't seen a ski with less than 180 hrs.
Oh and if you were to leave power on the info center so that the time counts up and then resets, Well it doesn't! You get to 999 and that's it. or it will spontaneously combust
To set the clock simply hold the set and mode down for 5 seconds, then press set to change the number and mode to move to the next number and then when your done just leave it and it will save that.
Also if you go to the speed mode and hold those buttons it will switch between mph and kph
