But thats kinda info that would've been nice to know. Maybe they didn't tell you! I don't know. I know if you had communication with 2wdw they always recommend the snorkel to be removed. I'd say I'm very satisfied and also the bike sounds a little cooler without the snorkel.Įehhh, ya never mentioned the snorkel wasn't removed, Shesahs. There is some jerkiness in first gear and at low revs in second, but overall, while driving, I barely notice any jerkiness. It accelerates really well, and the jerkiness is not nearly as apparent. I got it back and have ridden a few hundred miles with those things removed, and I'm very happy with the results. They flashed it for a removed snorkel and told me to remove my snorkel and 02 sensor, thinking that would fix the problem. I sent the ecu back and 2wdw said there were no errors with it. Plus, the dyno charts don't lie, you have had a gain in both torque and horsepower as a result of the flash. The spastic/erratic power delivery made the bike fun, but it's a heck of a lot easier to ride post-flash. Since the flash, I've never needed to rev match. I never had a motorcycle before (and I have had many) where I had to rev match like with the FZ. My bike no longer nose dives when I back off the throttle. I still have engine breaking but it's a heck of a lot less. Sure it jerks from the torque delivery, but it is smooth compared to pre-flash. I think there's a ton of difference between the spastic nature of the stock power delivery, and the cold reality that the FZ has a good torque hit when you crack the throttle. And you have no engine braking? For instance I can slow down from like 30mph to 18mph easy just reducing the throttle in second. So if you turn the throttle down, then back on, the bike doesn't jerk? For me it feels like it still jerks every time I reduce the throttle a lot, and then reengage it. The tradeoff was well worth it as I know longer have to work at riding it. But I will stress again that I was not happy with the flash at first as it lost most of it's in-your-face holliganism. That on/off crap went away with the flash, and fortunately, so did the engine breaking. ![]() The one thing you said "the on off throttle jerkiness is still pretty apparent" was not something I experienced. Once I got use to the new power delivery, I love it, and I too, would not go back to stock. The acceleration was just so smooth that it seemed as though it wasn't a devil child anymore. What I discovered was that my bike was every bit, if not more, quick as it was pre-flash. I would suggest that you ride it for at least 100 miles before you do anything. It manages all the running aspects of the engine and let`s the user know when something is wrong.I definitely had most of the experiences you have - my bike was definitely not as fun/spastic. The ECU is to an engine what a CEO is to a company. An ECU controls and maintains an engine in it`s optimum state by manipulating the sensors and actuators which result in changes of the air-fuel mixture, ignition timing and idle speed. There is a complexity never before imagined, and the Engine/Electronic Control Unit (ECU) plays a major role in the performance of the engine. Under the hood of today`s cars and motorcycles (premium ones) beats a highly evolved heart. There has to be a governing mechanism which controls everything from emissions and Air/Fuel ratio to power and torque. But as engines continue to produce staggering amounts of power and emissions take a toll on the environment there has come a time when mechanical advancements solely cannot do the job of keeping the engine in sound health all the time. When man`s fascination for speed and power reaches new levels and technology grows by leaps and bounds, engines cannot be far behind. It is always advancing, always growing and always coming out with better pieces of machinery. And the automotive industry is perhaps the greatest example of that. Therefore we must always be advancing and progressing forward, for this is the great law of life and living. The purpose of life is growth and development. We are electric beings vibrating within an energetic universe.
