Pete (faster faster) flashed mine coulnt be happier. No piggy back system to fail
Steve

Piggy back systems usually don't fail, except generally for 1 item being the wide band O2 Sensor that have an expected consumable hours life used to train & log AFR derived fuel maps. If it does fail, uplug it from harness & keep riding on your flashed map that you have previously trimmed yourself from AFR trimmed fuel map data.
By the time your piggy back's wide band O2 sensor fails it won't matter cause you'll already have an almost perfect map in your bikes ecu done with ECU Editor.

You know, a few days ago, my ignition coil cut push button up & down Pingel Easy Shifter started failing after 50,000kms from new, a few days later it was totally rooted, never mind, use ya foot, a bit painful on the 2 x DWDriver induced fractured upper vertabrae with heavy duty clutch springs though,... in a way, like unplugging ya piggyback ecu from the harness. Never mind order a new one, gets off a flight, US$876, on ya bike, & ya don't have to use ya foot or clutch no more. It's only money & it will keep you occuppied trying to work it all out which for some of us is a real challenge.
