Watch as Shiv explains everything you need to know about flash tuning in action from the dynamometer. Troy Siahaan of walks us through the process with Shiv Pathak of Open Flash Performance. We have decades of experience with the Dyno and tuning motorcycles tailored to your exact riding purposes and needs. In addtion, our techs have extensive certifications, including Ducati, Honda, Aprilia, MV Agusta, Suzuki, Yamaha, and Ohlins. V1 MOTO is an authorized Rexxer and Dyno dealership.Ī ll of our technicians, including our Certified Ducati and Honda Master Techs have been Rexxer and Dyno certified. The overall idea is changing your stock ECU's (Electronic Control Unit) parameters to safely build more power, deliver power smoother, and make it run as efficient as it can for your purposes. The problem is that your stock ECU has been de-tuned to the lowest common denominator, which is way less than optimal. Big Shout out to Thanks.The process is called ECU tuning, but it's also known as ECU flashing, remapping, and several other names. When you start to realise that this company also makes many of the parts that go into all the bikes. A top motorcycle racer commented that he couldn’t change gear that fast or that well. I swear it's the best ROI I could have imagined. The rebel 1100 is probably the class leader for power to weight in the cruiser market and the DCT makes it a clear winner. Iv'e had mine for just over 6 months and I'm feeling more and more enjoyment throwing this bike around using the gearbox downshifting into corners without the harshness prior to flash from 2wdw and as the turn opens up I can get on the throttle and the delivery is so much smoother, get it stood up, WOT delivers with great efficient linear response. Give it some more time and you'll start feeling the benefits through how you don't have to adjust riding to suit the bike's original nature. 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. 'However, I have read that flashing the ECU is a good idea for both power and fuel economy. Power gain was negligible without a power commander. Throttle response at all RPMs and in any gear became far better. I would suggest that you ride it for at least 100 miles before you do anything. My Z1000 became far more enjoyable to ride after an ECU flash. I definitely had most of the experiences you have - my bike was definitely not as fun/spastic.
