4/17/2024 0 Comments Yamaha bolt ecu flash results![]() Prior to the reflash it was a bit “soft” right across the rev range particularly in the bottom few gears in both sport and tour modes. As well as that it now goes like a 1200 should. The off idle flat spot is completely gone which is what I mainly wanted to cure. This is how it should come from the factory. “Darren, Got the ECU refitted late last week and had the chance to test it out over the weekend. What I’m also happy to promote is your good service and importantly good communication” I’ve recommended this upgrade to others that have the same bike as me. The acceleration in Sport mode is awesome, for a 260kg dual sport bike, and the usability in Touring mode has made the bike near perfect for what I want. I’ve seen the HP numbers to know there’s not allot of difference in the before and after but the bike is now a different machine. The throttle control is now much smoother (the main reason I wanted the upgrade) but what I can’t believe is the transformation in power delivery. Now that I have, I can say that I’m more than impressed with the result. I didn’t want to reply until I’d given the bike a few hundred km’s to get a good feel of the changes. Thank for your persistence with ECU Unleashed. “I got the ECU in the mail last week with the Gen 2 flash. So I would definitely recommend the ECU re-flash as it makes a bit of a slug into a very good bike.” A few times when I should have been on my Husaberg (slippery creek crossings etc) I’ve switched to the standard touring mode to make throttle response more gentle, I guess that’s what it’s for so not really a problem just an observation. Off to on throttle transition can be a bit abrupt at times more so than before ECU change. Power and response has increased from idle to 3000 rpm, from 3000 to 5500 rpm power and especially response have greatly improved. As I’m using the bike for long distance dual sporting I find that I’m using from 2000 to 5000 rpm in most situations so the improvements are right were I need them.įuel consumption has not been affected in fact at legal speeds has slightly improved. Since fitting I’ve done over 9,000 km so I now have a good idea of the results from the re-flash. Firstly the throttle response is much more instant especially at lower revs. “Sorry for the late reply to your request for feedback. Have a read of our latest three happy customers, their bikes were in various states of tune, from totally stock to full exhaust systems etc. However, if you ride overseas, they will be posting RON in most cases.We’ve had a heap of interest lately in enhancing Yamaha’s venerable XT1200Z Super Tenere – in way of our performance ECU remapping. Since the manufacturer recommends RON 95 no one including Ivan would recommend less than US premium gas.īottom line in the US, Mid range is probably acceptable as a substitute, but with premium you are always in the proper zone. Retail gasoline stations in the United States sell three main grades of gasoline based on the Anti knock Index octane level or AKI: Regular (the lowest octane fuel–generally 87 AKI) Midgrade (the middle range octane fuel–generally 89–90 AKI) Premium (the highest octane fuel–generally 91–94 AKI). For example, a 95 RON plus an 87 MON averages to a 91 AKI, which is the octane rating you would see displayed on a U.S. The AKI US Octane is an average of two other octane numbers, the RON and the Motor Octane Number (MON), which are determined by two different laboratory tests. On -1 under general Specifications it says Fuel type for all but CA, RON Research Octane 95. ![]() It runs terrific! I also bought a shop manual for it. ![]() I bought a 2021 Vaquero and have Ivan's tune. You can agree or disagree but that's what works for me and that's all that matters. Race Track, Wal-Mart, Quick Trip and other no names have gas just as it comes from the refinery. When that's not available I use BP, Shell, Chevron etc mid grade. I use COSTCO, because they are right around the corner and cheaper than anywhere else and the pump says 'Top Tier'. Come down a gear or two and I haven't experienced any problems. If you're in a higher gear and low RPM and crack the throttle wide open you'll gonna get some knock (pre-ignition remember?). Yes I'm Ivanized and I've used mid grade from day one. I've always been lead to believe that most if not all brand named or top tier gas contain detergents, etc. Premium is supposed to burn slightly slower to prevent pre-ignition, or engine knock if you like that term better, in high compression engines. From what I understand, and that may not be much, the difference is in the rate of burn. ![]() I wish I were sensitive enough to tell the difference of how much power I can feel between mid and premium gas but I'm not.
