[QUOTE="ionbeam, post: 1053822, member: 277"] Either that or the IAT sensor is indeed in ºC and your defective IAT sensor thinks it's 140º F. I can only speak for Gen I which shows everything in the MKS system. The FSM always shows prime metric measurements first and the USA values in parenthesis after. We need a Gen II (and maybe a Gen III) person to verify that your FJR really reads in ºF. It is unusual for this kind of sensor to go bad. I will note that my Gen I is selectable between km and miles whereas the Gen II isn't. Dunno if that may be related. Edit to add: The reading in F/C is just a math thing and computers are good at that. Usually when the base software is set out (like in 2001 World bikes) the software engineers don't go back in and mess with core code, they build on what is already written and proven. What you are reading in the diAG mode is what the ECU is using for inputs so if it has indeed changed to ºF some engineer was busy for not much gain. [/QUOTE]
