No experience with tuneecu but I do have DealerTool. I didn't have any desire to mess with the tune (Scorpion can w original tune) but I wanted the service options. DT resets the service indicator, runs all kinds of diagnostic tests, allows tuning of the throttle bodies and best of all, opens the ABS valving to allow bleeding of the entire system. Great service from DT and the initial purchase is linked to your VIN. Should you want it to work on multiple Triumph bikes, there is an additional fee from DT for unlimited VIN's. Great product!
