Because of my limited understanding of what’s necessary to properly remap an ECU I’ve made an error. An open road tune with a lap top using Protune connected to the ECU will not properly tune the engine. A proper calibration also requires hp and torque measurements provided by a dynamometer. The only dynamometer made for M3Ws I know of is at Krazyhorse in the U.K. I’m not aware of any in the U.S. My local V Twin performance shop is owned and operated by an American V Twin master mechanic who has worked closely in the past with the S&S R&D division. They are very qualified to work with the X Wedge engine. I’m going to have to go back and talk with them.
