I too replaced my 09 Uly's ECM in 2014/15, for the same symptoms. When relocating the ECM to be on top of the shock reservoir, it is in direct line of the fan exhaust so I installed the fan shroud from the comfort kit. It is a PIA to remove the rear shock now as I have to remove the seat pan, battery bracket, etc.... just as you do when installing the shroud in the first place. I think the benefits are worth it as the fan does not blow hot air on your ECM, reservoir, battery, etc.... everything under the seat. Also the fan shroud, with some dremel work will keep all your hoses from rubbing the rear spring as well as keeping them and the fuel line at the pump out of the heat. The rear shock though will always be warm as it is right next to the fan.
