Understanding the process, how the ECM works, what you are wanting to accomplish, knowing your setup, understand the data, and making sure you don’t have other issues that need fixed first are a must. Having your stock EEPROM and maps to reflash was critical. I also saved every revised map by date so I could revert to one if something went wonky.
I learned a lot in the process but got tired of the running down the rabbit hole and just wanted to enjoy riding and caring for her. In the end I ordered an EEPROM for my Buell with a Hawk exhaust, flashed it, and been happy since.
You can get good EEPROMs for most Buells and exhaust setups at reasonable prices from people who know their stuff that will work great. Unless you just have to have those couple extra horsepower or are an obsessive tinkerer,
