08 CBR600RR – electronic system upgrade Part 1

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.

  1. Awesome mas Bona… that’s one cool upgrade.

    Btw, have you ever had the CBR dyno-ed? I’m curious how many horses can the CBR produce…especially after all those upgrades.

  2. @Patrick
    No, never dyno my CBR. I would like it though, but the bike can not leave Sentul and there is no dyno facility in Sentul.

    The class is FIM Supersport. I have changed exhaust, foot step, brake line, and electronics. Superstock only allows brake line and adding silencer.

  3. salam kenal to om Bona….

    I’ve been reading this blog for a while and I’m pretty much like of the contents. Especially keeping up the progress of your new cbr from time to time.
    I’m only riding an F150 (same as yours, but different spec maybe), but I’m also an enthusiastist big bikes. Perhaps, someday I’ll be seeing you racing in sentul.

    Fyi, somewhere in citeureup, I know there is a Speedshop belongs to Bintang Racing Team, which own a dyno machine. Maybe you could dyno your bike there so we can understand how much hp this bike can produce after om Bona installed the new ecu.

  4. @Ekowd..

    Yup, my target is 1:40, but not to finish line… 1:40 to S Besar.. huehueheheheh


    Hi there.. Glad that you like the contents of this blog 🙂

    The CBR is not brand new anymore. Changed several components and crash with it in Sentul turn 3 already.. hehehe. Anyhow, I do want to dyno the CBR, and I did heard about Bintang’s dyno. Yet the logisitic of taking the bike there may be too much.

    But, no worry…. there will be full report if I manage to get my CBR dynoed.. 🙂


  5. I miss this blog…. It’s been a while since I last came here.
    Anyway, after reading this post, I keep imagining Bona racing his CBR with a laptop on top of the fuel tank & fiddles with it to change the engine mapping/fuel mixture/etc every time he enters a corner/straight in Sentul. Hehehehe…
    Maybe you ought to alter the clip ons to F1 style steering wheel (with numerous buttons & dials to change the electronic settings)? hihihihi….

  6. wakakakaka, sandbagging… it is a reality bro.. but, tell me, does this change give you additional power, er, I mean, do you feel the difference? I need to do something with my bike to keep up with you , hmmmm….

  7. @Didi..

    Eddy remap the cbr during our lunch brake last saturday track day. The engine noise is more “screaming” now. Also no more back firing. The cbr back fire aoften after I changed the exhaust. Now no more back fire, I guess the mapping already suite the HRC full exhaust..

    As to the power, the throttle is bit sensitive also. It pick up rev quicker.

    As to my lap time? No change…. It is the rider not the bike.. huehehehh

  8. wow….nice part,…wanna take a look closer and try it too. ive seen u Sir,
    really fast on corner lately. it seem like Pedrosa,….hehehe
    i hope many racer would gave us theirs secret as much as u do Sir,….
    have a nice laps, must be the white fast now on weekend”

  9. Does a similar kit exist that also accomodates the regular electronic function of the bike like: Traffication loghts, Night lights, Ignition Switch, Stop lights. If not is there a different similar product.

  10. What a cool device Bro Bona!!

    I Bet the system can run sequintial injection spray.. NICE!

    IMHO, the setup will be better on a dyno though..
    I mean it’s not all about horse power, but on a dyno we can set the nicest and crispiest throttle responce.. Fast, but smooth.. 🙂

  11. @Phanos:

    Hmm not really sure about your question, but I have no info about other kit.


    Thank you bro, I plan to dyno the bike soon, stay tune… 🙂

  12. Bro Bona,

    IMHO, I am not dynotest fans (no more), because the system only measure Horse power/Torque by guessing of course it is computer calculated guess.
    And it will ruin your rear tire, do not use tire that have been expose to dynotest for racing, there is possible of internal failure.
    And the last one it is tested on dyno enviroment, not real condition of racing track.

    Since your bike, at the circuit, the best way is to get maximum adjustment based on circuit enviroment, one of tool to use is Air Fuel Ratio monitoring system that utilize WIDE BAND O2 sensor, monitor your engine combustion result and do further adjusment as necessary at ECU MAP.

    Create ECU MAP as many as possible based on circuit enviroment, track temperature, humidity, etc, so you will be ready to plug in any MAP if the track conditions changes.

    The real RACING BIKE test on the track not on a machine called dynotest, No offense.


  13. @bengkelsepedamotor..

    Thanks bro, wow very good write up and suggestion! Will try to do that!

    I guess, my main reason to dyno the bike is to measure its max capability power and torque wise. Since without dyno I will not able to determine what are its hp and torque figure. Bare in mind – I no pro racer, so most of the time I do not ride the CBR to its max, with dyno perhaps I can get the figure of the max capability of the CBR in term of hp and torque.

    You right about the rear tire, we do not use new or track tire for dyno. Our mechanic change the rear tire prior to dyno with used tire.


  14. Bro Bonadjalins,

    REAR WHEEL DYNAMOMETER, measure how fast/good your motorcycle rear tire can turn heavy steel roller in it and computer software will calculated time, rate of acceleration to a given engine speed.
    As result is a nice print out of HP/Torque.

    Air pressure of the rear tire, the force used when strapping the bike down, drivetrain efficiency (clutch condition) can significantly affect power reading.

    Used tire for dyno test ???


  15. Bro bengkel,

    Yup, no way I buy new tire just for Dyno.. hehehe.. I did have sevaral “used” tire from the track. They are certainly not old or in bad condition, I used them for about 80 – 90 laps at Sentul. Usually for race I use new tire, so I do have a few set of “used” tire which I plan to use for dyno.


  16. Bro bengkel,

    Yes, I read it once that HP can be measured in wheel or in the cranck. Obviously the cranck figure will be higher with the drivetrain out of the equation.

    I do not have data logger, and they are – like the D2 – just way to expensive.


  17. 06300NKZ671 CBR600, DATA LOGGER KIT $ 922.30
    Check your ignition setting (detonation).

    I didn’t see it has AFR tuning aids, but can use aftermarket one, this is highly accurate with less than ±0.10 AFR error over 10.3 – 19.5 AFR range, can log up to 2 hrs of data, at $ 399.50 ($ 399.95 at Muzzys.com)

    So with those kit above can tune ECU Map at its best and suit to track and your riding style (both loggers monitor your throttle opening behavior).

    Thank you.


  18. Bro Bona,

    Yup… that’s the one.

    Yes I will support you to install this, please email me for details to: bengkelsepedamotor at gmail dot com

    Your “R” ECU need those two above more than just dynotest.

    Monitor your detonation, monitor and set your AFR at 13,8:1 welcome to computer world for your motorcycle.


  19. @ bro bengkel..

    Sure we can adjust our bike by AFR Ratio meter.. but if its come to adjusting ignition mapping, the only tools that give us clue that we are on the right step, is dyno.. Honestly, i can find another device that give such information like dyno..

    Please don’t say rider feeling.. 🙂

  20. hey that HRC wiring and ecu eliminates the key and ignition right? what do they use instead? do they provide a toggle switch or something? thanks

  21. i thought the harness would allow u to remove the keyed ignition alltogether and just have the handlebar mounted switch only.
    you are saying that you dont need a key but the ignition switch is still there to turn on the bike. how does that work. sorry if i’m not understanding. thanks adam

  22. I mean the ignition switch on the handle bar. I have removed the ignition switch. To turn on the bike simply switch ON the ignition switch at the handle bar and press the Start button.

  23. Hi i*m from argentina(I don*t speak english a lot).I bought a crashed cbr 600rr 2008 MADE IN JAPON ,the switch is broken, I want to know if i can start it without the IGNITION SWITCH,i must cut some cable?or i must put some cables together? I haven*t got the meter because it*s broken too,,in argentina is so difficult buy parts of this bike,HONDA ARGENTINA haven*t got stock.THANK YOU VERY MUCH ..Waiting your answer MIGUEL…

  24. Hi Miguel,

    I think you will still need ignition switch, sorry can not help you much in this case. I suppose you can buy the replacement switch some where..
