![]() ![]() I’m traveling but will try to post pictures and a video with sound later this week. They took a long while to receive, but the wait was more than worth it. I received my Hattech Sidepipes (with the “works” finish) on Sunday, and we bolted them on right away. ![]() The perfect motorcycle for determined hot-rodders and do-it-yourselfers." The ONLY brand I have had issues with over the past year is BMW).īMW's new advertising for the R18 should be "Expensive unsupported motorcycle, fantastic motor, decent performance, poor factory support, no accessories, and crappy dealer service. I admit I have a love-hate relationship with BMW.I love this motorcycle and I hate the way BMW has treated the buyers ( and PLEASE no more "pandemic/COVID/supply chain crap.BMW chose to compete in the American cruiser market and the other brands I deal with, including Harley - love it or hate it - have fully continued parts and accessory availability along with a full compliment of shop/service info & equipment. Once a tuner is available I will open the intake, remove the cats and the butterfly flaps, get a good mix going and run it like God intended. My bike exhibits no "too lean" symptoms/conditions. Not ugly loud the 02 sensors did their thing, and according to my seat-of-the-pants dyno the low end performance was improved and the high end unchanged, all as expected. I haven't done anything to the intake or cats or flaps but I did install Hattech mufflers that I special-ordered for off-road use only (great company and product by the way). I don't have a stock R18 fuel table in front of me but many bikes cannot properly tune themselves to, say, a full exhaust because it is out of the allowed range. Yes, however there is an acceptable range allowed by the stock maps. Maybe those guys got lucky and slipped through the cracksġ. I had assumed this would immediately void any warranty and Big Brother BMW knows all. 2/6 had done major warranty repairs (engine related) on tuned s1000rrs also no issue with claim approval. Out of curiosity I have asked about 6 BMW service departments about this issue: all 6 had seen a late model s1000rr in their shop with the bren tune, hooked it up to the computer, and had no issues. I believe their business model now is for you to buy their handheld tuner, that way you can flash and unflash as you like for dealer service reasons. They recommend flashing after the break in service (because that bike is wiped and remapped after break in) but software updates and the like do not seem to affect it. Bren tuning has had great success with the 2020+ s1000rr, considering they are so cucked from the factory. ![]() I don't have a stock R18 fuel table in front of me but many bikes cannot properly tune themselves to, say, a full exhaust because it is out of the allowed range.Ģ/3. So do race exhaust + smog block off plates + fuel remap / ECU flash + race air filter all together in one upgrade.Click to expand.1. You also want a race air filter to increase engine air inflow to match the higher outflow you get with the race exhaust. If you are running tracks at high or varying altitudes you also want the optional ftECU ActiveTune feature that comes with replacement better oxygen sensor. The bench ECU flash harness doesn't require any wiring work you just pop the ECU out of the bike to flash it. The advantage is you can tune your ECU at the track with just a laptop but I have never felt the need to do that the bike just ran like a champ all last track season. One caveat is the on-bike ECU flash harness is a PITA to install because it involves a bunch of fiddly wiring work. Way simpler than other aftermarket quick shifters that do not leverage the ECU. A major benefit of it is the optional quick shifter add-on which only requires a single additional harness to the ECU. I went with FlashTune instead of PowerCommander because of its additional features and the fact it doesn't require an extra box. Yes you have to remap or flash the bike with a race exhaust - if you don't the engine will run too lean and heat up and not make all the power it can. FYI the smog work requires removing the tank and working down by the fuel injectors. And when you do that you might as well get and install smog block off plates since there is no point in keeping any of the engine smog components with no cat. Yes you have to remove your cat when installing the race exhaust - it is connected to the stock exhaust and removing it saves major weight. Sportbike Track Gear generally has good such videos. I figured it out using a combination of whatever official written instructions I could find and the right install videos on YouTube. I put a full Akro race exhaust on my 2016 R6 track bike successfully before the 2021 track season having never done it before and not being a mechanic by trade so it is doable. ![]()
