This is something that quickly becomes second nature and is likely better for the motorcycle anyway.Ģ) The warranty may be affected by the use of the tuner as it piggybacks onto the ECM. The only dislikes I do have with the system are:ġ) When the bike is started it is necessary to idle it for 20 - 30 seconds before taking off or the RPM's won't come down properly until you stop for the first time (the engine will stay at 1300 - 1500 RPM's for a few seconds at the first stop). (I tend to ride at a higher RPM than a lot of the folks I ride with, keeping them above 2000 - 2500 most of the time - try it, you'll like it!). The bike runs great now, I don't have any issues with backfiring or heat, starting issues or lags in performance at any RPM. The changes bought on by the system aren't really immediate, you just sort of notice an improvement over time shortly after changing parts. There were no noticeable negative effects from either, and in time, the tuner optimized the fuel mixture so I noticed more power. I soon added a Big Sucker air cleaner and gutted the factory catalytic converter for better flow. The indy didn't tell me this would happen, so it was a nice surprise. There was an added and unexpected benefit of no more throttle-by-wire lag when I got on it hard. I can't pin down exactly when it happened due to weather and trip length differences but the bike was just acting more like I wanted it to act. The heat issues went away within a couple of hundred miles from installation. My local indy shop had installed a lot of these tuners and had great results with them and comparing the ~$400 installed price for this system to a lot of the other ones out there I decided to try it. The power was a little better but the heat issues remained. First I added Rush slip-ons and a Harley high flow air cleaner. I had a lot of heat issues, mainly loss of power after sitting at lights in hot weather and decided to find a fix. I purchased my 2012 Ultra Limited (103 cubic inch) bone stock and new in the spring of 2012. Since I couldn't really find any useful reviews on the RC Components RCX-celerator tuner online before buying one myself, I thought I would write a few lines about my experience with the product.
