Great write up. One question that I have. If I get a dyno tune with the bazzaz z-fi, getting the bazzaz afm would be redundant, correct? Would I be able to switch between the tuned map and auto tuning?
Yes and no. Dyno tuning is much more comprehensive, and it gives you the ability to determine what the exact ideal AFR for your bike is. Using the Z-AFM while riding gives you the most realistic tuning, since your bike is operating under real world circumstances. Our Z-AFM is not an auto tuner, per se, it's a fuel mapper. The Z-AFM operates more like a data acquisition sysytem, it logs data while you ride, then you go back in and review the data before applying the recommended changes. This gives the user absolute control over what goes into their fuel map.
It's not really necessary to continually tune your fuel map, your bike's atmospheric sensors do a fairly adequate job of keeping the fueling consistent with pressure and temperature changes. I can ride all weekend, from sea level, up through the mountains, into the high desert, and then up some more mountains, and I never notice a performance change in my bike. I re-map about 4-5 times a year, seasonally, but only b/c I have the z-afm and I can. The biggest advantage is for track riders and racers, it is much more essential for them to re-map at every track, since they are in the hunt for hundredths of seconds off their lap times. Street riders aren't going to notice the difference most of the time, as long as they have a good base map to start with.
When you get it dyno'd the map is for the conditions on that specific day, when you use the autotune you can set it up to whatever the conditions are there and then which is better. One thing I was wondering (question for eviltwin) is when your bike is on a dyno it isn't moving obviously, but in the real world when you're doing 130 the bike is getting air pretty much shoved down its throat (might be called the ram air effect??), so does that mean the map on the dyno will be less accurate because once you get the bike off the dyno and get on the road the extra air pressure in the airbox will change the AFR?
You are absolutely correct, and this is something that is often overlooked; ram air effects do change the fueling requirements in a tune. Most dynos either do not have a ram air simulator or it is a fixed speed system, which is still inaccurate. Our dyno has a ram air simulator that can produce wind speeds that mimic up to 170mph of real world ram air effects. This feature combined with our incredibly smart and accurate load cell, which can apply progressive drag that mimics wind drag, gives me the ability to make maps that are damn near spot on to real riding conditions.
