The Bazzaz Unit has a limit of 63 percent additional fuel.  Thats the limit of the injectors anyway so going more than that would require larger injectors. 

8)   That should cover about anything you want to do to it.  I know the turbo's we've done have topped at around 50%.

OK... I have a second here.

The Bazzaz Unit works several ways.  Their website is www.bazzazperformance.com

Dont get hung up on Retail, I'll work pricing for you guys.

The Bazzaz is a piggyback on the stock ECU.  You program it with a laptop via the software it comes with.  It works like an excel spreadsheet giving you values for RPM/Throttle position to adjust fueling.  You can build a map or download preset maps, it also comes with a good base map.

The best way to do it is with the add-on AFM unit that comes with a wideband A/F Sensor and the amplifier to hook into the Bazzaz piggyback.  Then you go into your software and set target A/F ratio's.  You can set the entire range for say 13.5/1 or you can adjust certain areas of the map to run richer or leaner.  Many units you can program certain RPM's in each gear as well.  So you can REALLY customise the way your machine runs.  You can start the automap program and go run then look at the map and lock it in or you can just let it continually automap every time you ride.  It will adjust on the fly for exactly what you are doing.  It takes less than 5 minutes to work with the mapping and get it going.  Once you have done it a time or 2 you can do it in a couple of minutes.

This technology was built in Professional Superbike racing to take the guess work and constant dyno runs out of the equasion, it's time tested and works very well.  We install 3 - 5 a week in our shop and most of those are from referals form customers we did an install for.

ECU Programmers have come a long way.  The Bazzaz unit is without question the best we have worked with.  We have been using them on SuperBikes in Pro Racing for a few years now and the ATV/UTV units are amazing.  You can either do a stand alone EFI unit and program it or you can add an A/F sensor and plug in ratio's and let it self map.  You can make adjustments anywhere in the RPM range by RPM, throttle position and gear selection.  It's a very cool system and we have a lot of experience with them.
