I have left my stock one alone as well. I run the 08+ Erik Buell Racing Ecm A couple of weeks last year.Plus track days in Daytona/and Jesup Ga.& also atlanta. Power is a little better No popping on decell. Matter of fact the lite came on today coming back from the Base, getting ready for Bike Week.Now I Guess I'll send it Back & see what the deal is. Bike seems to run fine. Oil pressure is good ,I've installed some guages for voltage/oil etc. Hate just a lite to go by.On THE EBR ecms THE fan run time goes back to the orignal run by sensor/temp. only. The STOCK-Ecm, Runs the fan by speed as well as temp.This is a good program for everyday riding. Cools the bike pretty good. Yours is 2009,so I hope you have the newer ecm update.BTW- does your bike have the update. The warranty is from 1st owner date of purchase, as follows 2 yrs.unlimited miles except wear items.EPA related items 5yrs.or 18,600/or so miles.As long as theres no hacking etc.Parts covered-Ecm-02oxy.sensor,Temp.sensor for fan, IAT-or internal air temp.(inside air box).Even the muffler is an EPA unit cause of E-mark,catylic inside w/ active exhaust valve.Might want to put some miles on Ecm before replacing. Post up when can.
