![]() Coming off my perfectly fuelled throttle cable driven carb'd FZ1 this was a pretty big difference. On my first ride home from the sellers house I didn't think it was ALL that bad until I stopped to put it in A mode, rounded a corner and got on the gas exiting the corner. I read a lot about this bike before I bought it, including all the horror stories about they jerky drive by wire throttle. Throttle response/snatch - We all know this is the biggest issue with this bike Since getting the ECU back I have never tried the other modes. All comments below relate to the bike in A mode in both cases. One of the options of the flash is to have the bike start up in A mode - which I did. I agree, these bikes don't make a ton of power but with their ample low end torque it's nice to have them as smooth as possible. He also mentioned that for his particular bike that the ECU makes a much larger contribution to enjoyment than the exhaust does. Ivan noted his flash can handle 95% of what you throw at it, and fine tuning (if needed) can be done with a fuel controller (PC). I am still (for a few more days) running the stock exhaust. I never rode the bike with original Yamaha flash as I bought it used. My bike is a 2014 with the 2015 updated Yamaha flash. The ECU was turned around very quickly and I eagerly slapped it in. I chatted with Ivan and mailed out my ECU. Not much to say here that wasn't mentioned above. I began talking with Ivan about his fix for the FZ-09 and was impressed with what he had to say and knowing that his products work - the decision was made. Ivan has always answered quickly and honestly and I have come to know him a straight shooter who will tell it like it is. Over the years I have constantly bombarded Ivan with technical questions which were quite often not even related to his products. With both versions the bike ran flawlessly and exactly how he describes on his website. I purchased his MB Jet kit, and later switched to his POD kit. I first became aware of Ivan when I purchased my first gen FZ1 about 5 years ago. Reason for choosing Ivan's Flash vs the competitors Previously my bike had the 2015 updated Yamaha flash, which will be used as the baseline. Having talked with him directly, I now have a clear picture of what Ivan is doing, regarding the modification of the Raider's ECU.Here is my review of Ivan's ECU flash for the FZ-09 which I have been running for about 3000 miles. Quote from: Paladin on Mar 12, 2014, 04:44:23 pm I just had a long conversation with Ivan. Based on Ivan's Dyno charts, I think he's on the right track. regulations, he doesn't have to compromise and can reprogram the Raider's ECU to enhance engine efficiency, thereby increasing performance. Because Ivan isn't restricted by State of Fed. Therefore, Yamaha has set the Raider engine's rev limiter accordingly. Yamaha has set the Raider's fuel and ignition curves where they have, because Yamaha needs to meet Fed. ![]() Knowing what I know about the Raider's engine, which is pretty extensive, I feel comfortable with what Ivan is doing. Ivan is also adjusting the ignition and fuel curves to take advantage of the increased RPM range. ![]() limiter setting will be 5850 RPM, which is within the engine's safe piston speed operating envelope. limiter, he's moving it higher in the engine's RPM band.
