I had a Bazzaz unit with auto tune on a KTM 990 I sold. The fuel controller was easy to use and it came with the proper connectors so no splicing was required. Good support with any questions. I would say it a good option vs PCV. I not going with a auto tune for my Tenere but will have a PCV installed and a custom map built by Ken Wheeler at Wheelers Cycle in Robinsville NC. If you are going to make changes to the engine, exhaust,, air intake over time the auto tune is cool.
I do see the Bazzaz will work with a quick shifter, that would be a nice feature but it is an additional expense.
