Check to see if it has the auto tune feature, if it does you'll have 02 sensor's, if not it will need to be tuned or install a canned map. The auto tune can be programed by you with a laptop. All you would need to do is go to the zipper's web site and download the pdf manual. Then just follow the instruction's. It's easy!

Had one with auto tune. Kept fighting timing issues... went back to racetuner. If you never had a tuner, any will work on properly tuned... wasn't a significant gain over the racetuner tune I had...

I've had two of them, one for three years on a previous bike and the most recent for 1-1/2 and no problems with reliability so far. I've also been very satisified with performance and tuning flexibility.
