I just installed the Bazzaz Z-Fi fuel controller on my 2017 SV650 and took it for a 45 minute test ride. My bike is totally stock, except for a G3 ergonomics throttle tamer. I'm using the enhanced map that comes preloaded. I see no improvement in the bikes performance at all after installing the Bazzaz unit. I was shocked. And actually, the bike's throttle response is worse. When I do full throttle roll-ons starting at 35mph in 3rd gear, there is a slight but noticeable delay in the throttle response. Before I would get an immediate surge of power as soon as I twist the throttle fully. Now, the bike moves but the surge happens about a second later. My guess is the the Bazzaz is causing delays due to the time it takes to process the signals it receives. Weird. There doesn't seem to be anything wrong with the unit or the software. And my bike doesn't feel like it lost power. If I'm just riding normally (not full throttle) I don't really notice any difference from stock. If Bazzaz "smoothness" means delayed performance, I'm not interested. Very disappointed. I'm going to mess with it for a little while longer but I get the feeling I'll end up removing this thing. I did not dyno my bike and don't plan to. Has anyone else had similar results? Better results?
