PCV vs. Bazzaz
------------------------------------------------------------------
Both the PCV and Bazzaz essentially do the same thing. There are minor differences between the two though.
Out of the box the Bazzaz does help control both the lower 4 and upper 4 injectors. The PCV only controls the lower 4 injectors without an additional add on. Having control over all 8 injectors does allow for a better mixture, and generally results in slightly better low to midrange power.
The Bazzaz is slightly more complicated to install. The Bazzaz requires hooking into both upper and lower injectors, CPS, TPS, speed sensor, switched power source, and of course a ground. The PCV only requires a connector for the lower injectors, power, and a TPS connection made at the ECU. Also complicating the install of the Bazzaz are sub-par instructions, no pictures are included. The PCV comes with very good instructions, and includes pictures of each step.
Agg2001 has a very good Bazzaz install how-to that will help if you run into problems.
Next the actual software is pretty similar. However a few minor differences. In both you have an RPM/Throttle table where increase or decreases in fuel are made.
PCV Software:
Bazzaz Software:
You'll notice in the Bazzaz software there are more throttle positions to tune at. Bazzaz goes 0 - 5 - 10 - 20 - 30 - 40 - 50 - 60 - 70 - 80 - 100, while the PCV only does 0 - 2 - 5 - 10 - 15 - 20 - 40 - 60 - 80 - 100. However you'll notice the PCV offers some more tuneability down low, that the Bazzaz doesn't have, but then up higher the reverse is true. It should be noted that most people will only use 0-20% when riding on the street. Personally I give the slight advantage to Bazzaz here for more adjustability up top. The Bazzaz software also has a few other features that are interesting. First of which is the ability to simply just increase percentage of fuel across the whole map based on gear, for example 6th gear can be 2% richer than the base map. While this is neat and easy to use, the PCV software allows you to have completely different maps for each gear rather than just broad changes to the entire map (
Requires hooking the speed sensor wire to the PCV). The Bazzaz software also allows you to change multiple cells easily by selecting them and choosing how much up or down. The PCV software also has this functionality but it's not as obvious, the Bazzaz opens a dialog box and you choose how, the PCV software you select the cells and use the page up or page down buttons. The Bazzaz also offers a smoothing feature that averages out the cells selected and attempts to prevent radical changes. From what I've seen this sometimes works, sometimes doesn't, the smoothing feature will many times take a huge figure like 28 all the way down to 8 because there was a 5 next to that cell. So results with this "feature" maybe hit or miss. The PCV can create maps based on 500 or 250 RPM increments offering slightly more tuneability. Also the PCV can be hooked into the coolant temperature sensor to tune differently based on engine temp (Admittedly I can't see a reason to do this in our application, this would be more useful for an air cooled engine, like Harleys). Both offer the ability to use a switch to flip between two different maps if you wished. The PCV also allows the switch to turn off or on various functions/add-ons.
The add-ons, or expandability is where these two devices differ the most actually. Available for the PCV are Ignition Module (modify timing, adjust rev limiter, etc), Quick Shifter (allows upshifting without the clutch), AutoTune (tunes the fuel map on the fly as necessary), External Display (displays info from the PCV), and Secondary fuel module (controls the upper 4 injectors), all of which can be added in any order at any time (exception, quick shifter requires either secondary fuel module, or ignition module, ignition module is the strongly recommended route to take with the quick shifter). The Bazzaz offers an "AutoTune", Quick Shifter, and Traction control. The down side to the Bazzaz is only the "AutoTune" zAFM is the only add-on that can be added separately. Adding the quick shifter and traction control require buying a the module in advance that supports these features, they are not added on later or seperately. There is a quick shifter stand alone unit available for the Bazzaz, but it's ridiculously priced.
Between the two, one of the biggest differences is the AutoTune and ZAFM. The PCV AutoTune makes live changes to the map as you are riding, meaning it is constantly making changes needed to achieve the AFR you set. The Bazzaz unit monitors the AFR makes an educated guess at what needs to happen to the fuel table to achieve the desired AFR, then you must accept the change before it happens. If the "educated guess" is still off it will keep changing it's suggestion until it reaches the desired AFR. Also note the PCV is working the same way, it is still taking educated guesses at what needs to happen it is just applying those changes as you ride. Applying the changes automatically as you ride, does ensure your AFR is always where it needs to be no matter, what environment you ride in.
