Sending out your ECU is a good option but not the best. Those are variables that do make a good bit of difference. It'll get your bike close, and most likely put it in a safe realm for fueling but that map wasn't designed on your bike, with your pipe, in your state, at your elevation, with your fuel. You're looking at about 400 bucks to make sure your engine doesn't eat itself and get the best performance.Įdit: I should note that reflashing isn't the best option. Essentially, the bike was set up in a way to perform, but also pass emissions.which doesn't really bode well.Įither way, if you wanna whoolie for longer periods of time and maintain erections that last longer than four hours, don't be cheap and get a proper map done for your bike. The FZ is kind of known to have jerky throttle response, and it's because of improper fuel mapping. The other benefit is that a proper map is going to help smooth out your throttle response.

Add a full system, which allows the engine to breathe more efficiently, and you'll then get an engine that is running even MORE lean, meaning you'll have more opportunities to ruin your engine. In stock form, your FZ is probably already on the leaner side. So, what's the point in adding something that will sap power and eventually ruin the engine?Ī proper map is going to ensure the optimal fuel/air mixture throughout the ENTIRE rev-range. If you were to put the bike on a dyno, I absolutely assure you that you'd see a MASSIVE dip in the mid-range, which is exactly where you'll be riding the bike the most. It'll run, and the main problem is, you could feel a little bump in torque off the line, so you'll be tricked into thinking that it's all good. This causes the engine to run much hotter, and can lead to piston failures, ring failures, valve tapping/wear/damage. So that means more air than fuel is in the mix. What's most detrimental is having an engine that is running lean. Problems from not reflashing/using a PC/Bazzaz/whatever come in many forms, but bottom line is that is causes premature wear to the engine, wear that shouldn't even be showing up until the 100K marker. The thing is, even a slip-on can will alter the backpressure, and thus change the optimum fuel/air ratio. Some people can get away with running a slip-on fine, but NO ONE will get away with running a full system without a retune. It's all subjective, and that's the problem.
