OK fellas,
I just bought an 07 FLHR and removed the obnoxious sounding Thunderheader slip-ons that were on it, and installed V&H ovals. I'm ready to install my FuelPak but I don't know if the ECU's been flashed?? I can't reach the original owner but I can call the original selling dealer.....if he bought it where he lived????? My question is can you determine if the ECU's been modified and how without taking it to the dealer? I don't want to plug in the wrong values.......Help!!

 

The dealer can read the file name of the currently flashed version, sometimes for a price. If you have a buddy with a SERT or TTS those tools can also tell you the file name of the flash. No need to get married to read out the info.
