Just curious if an EEPROM could lose data if powered down for years?
My DL1000 had the hiccups between 3k-4k rpm. I used the loaner Yosh Box from one of the V Strom sites and richened it up and it was good for 20k+ miles after that. A few years ago I mothballed the Strom and now I'm going through it and fixing it up to ride. Among other maintenance I Kreemed the tank and replaced the fuel pump. Got it where I think the fuel system is 100% and on my test ride last night the hiccups are back between 3k-4k RPM!
Now it's my understanding that an EEPROM can't really lose re-written data which is what the Yosh Box does. Otherewise it could lose the whole map, right? Or is the factory map somehow not rewriteable, but what I'm really doing is modifying look up tables? IDK.
I'd like somebody to tell me that the ECU could lose this tuning and revert to stock if left unplugged for years. Then I'd know that the fuel system is probably good to go. Right now it makes troubleshooting difficult.
