![]() Some of it is easy and obvious for me, having dyno-tuned (on a Factory Pro dyno) hundreds of OEM ECMs both race and stock, sport bikes and Harleys. I'm new to FTECU, but tuning methodology remains the same. I know a thing or two about tuning so if there is considerable decel popping, I know how to get rid of it using FTECU. So I'll be starting with the Unrestricted file with EXUP disabled, Closed Loop disabled and AIS disabled then make incremental changes from there. I'm too much of a control freak to NOT know what tweaks exist in the file. I think the PC on top of the Graves file is probably your only option, if you want to keep the Graves maps. I haven't done it with my bike yet only because everything will change after the exhaust changes. RPM Map in the smaller throttle opening areas. I'm pretty confident I can tune it out by adding fuel on decel or in the Fuel TPS vs. The very slight decel popping I'm currently hearing after Disabling the AIS Valve (using the FT ECU software) only happens when the engine is cold. If I experience the same popping after removing the EXUP and installing the Graves mid-pipe then I will play with the appropriate settings to tune it out. But making changes here to correct engine braking is very easy as well. So the Unrestricted file is the same as the Stock file in this area -the values are all zeroes in both files. Basically, the Unrestricted file opens the throttle to 100% in a broader range than the Stock file. You can start with that and adjust according to your riding style and comfort level. So somebody at FT ECU spent time changing these values. They have different Throttle-by-Wire values. I compared the Unrestricted file with the Stock file. That's where the real value of the FT ECU is. If not then create your own tune for your unique bike, and change it when things change on your bike. If they work for your bike and you're happy then great. So I don't see how anybody can complain about that. So the canned maps have limited value anyway, but they are free after all. Absolute optimum power tuning for each bike would require a unique tune for that bike. The smallest manufacturing variations will create different demands. The pre-packaged Graves maps are designed to work with the Graves systems. You have access to everything, unlike with the PC5. It's far better than using a Powercommander. The product is as good as any Race Kit ECU and the software used to tune it. Chuck gave me a demonstration of the software and I bought the FT ECU right then and there at his shop. I knew about the Graves maps being locked down before I bought the FT ECU. Once my exhaust arrives I will reflash to graves file and report back.ĭon't get me wrong, I don't regret the purchase at all. I have not tried the Graves file yet, im sure as typical with Graves their products have excellent R&D, but thus far im not to happy with the FTECU file on its own, which on other motorcycles that I have had flashed with them, I was. I wanted to have a great start point and fine tune if needed from there. ![]() ![]() For someone like myself who can admit that im not all familiar with how to make changes on the software, and what increments to do, I wasn't really looking for project of dialing in the bike from scratch. Certainly didn't feel like any additional power was gained from the unrestricted map and even things that FTECU always does well like heavily reducing engine braking wasn't really changed and required the user to go in and make changes. However on the R1, while I was expecting the same, aside from changes of removing some emission based components from the bike really didn't feel any difference to my surprise. In my past experience Flash Tune has been pretty thorough with their base tunes and generally I have noticed large changes right out the gate. ![]() I did not modify any settings from the already made Unrestricted file. I started flashing the bike with only the FT ECU unrestricted file as I do not have my full exhaust yet and only have a slip on. Software install straight forward but software driver install was difficult for some reason. Removal of the fairing and ECU was very easy and done in less then 15 minutes.įT ECU kit, straight forward decent quality harness. Purchased from the Graves the Flash Tune Type 18 Bench Flash Kit
