change FLYDAT set up

Hi,

I have a flydat 886857 with the CD rom and the RS232 cable (jack 6.35mm to communicate with the fly dat). it is actually set up in °C and for a rotax 912. I would like to convert it in rotax 582 in °F, i bought this flydat from second hand and i have all the face plate for all engine 2 and 4 strokes in °C or °F. i read that it is the dealer which could do this conversion but nobody would like to support flydat now, i think it is just an upload but i can't find any information on the net.

does somebody know the procedure to do it ?

thanks a lot for your answerS.

regards,

richard
