Notice anything different about the CBR600RR dashboard above? Yup, there is no RED LINE! All the way to 18K RPM! Above is the pic of HRC CBR600RR dashboard that is part of the HRC’s wiring harness and race ECU that will be installed on my CBR track bike.
Well, not that I need more brute HP and increase performance from the CBR – I might only use less then half of its stock power capability *I think* – but this is one of the thing that I enjoy the most. This upgrade given me the capability to tune, tweak, and play around with the CBR electronics directly by using the software provided by the package. After all, the CBR is a “grown up toy”, and this upgrade gave me more tools to play with.. yay!!
See the HRC’s package for CBR600RR above. The main components were the wiring harness and the ECU. The wiring harness is the “nerve system” of the bike. Just like the nerve system in our body; wiring harness connects the brain (or the ECU) with the rest of the body. Most importantly wiring harness connects the ECU with the engine, or the injection system which Honda calls the PGM-FI system.
Picture above, R15 mechanics preparing to install the HRC’s wiring harness by removing the stock harness. Since HRC is a race components, its lack standard/normal bike features. For example there are no more wiring for any lights, ignition switch, or even speedometer. All are not necessary. After all this is a pure race bike!
Picture above, the stock wiring harness on the left. Compare with the HRC wiring harness on the right. The HRC wiring harness is much simpler with less wiring and connection. Lost your key?? What key!!
The stock ECU above. Will be replace with HRC’s race ECU bellow. Notice the “R” series..
The ECU main function is off course to control the PGM-FI system. See bellow the 4 injector with the colorful wiring. That stock wiring got to go.
HRC’s ECU have several “race” features that stock ECU do not have. Like pit line limiter, once engaged the ECU will limit the the speed of the bike electronically so you do not brake the speed limit during pit pass. Nice eh!
“Brain” is nothing without “information”. Information about timing, fuel and air mixture and so forth. This information is called Map. This information or map was kept at the ECU. And the ultimate feature of a race ECU is that you can create your own map that suite you riding style, the track that you ride or even the time of your track/race. Race ECU with accompanying software will give you that capability which is why they are so important for a race bike and team.
