  1. I thought shinko tyres where made by one of the larger mainstream brands like bridgstone, same technology same material just branded under a different name, large companies often do this to get market share

    ECU

    Dont know if it was mentioned already, but your best bet would be to buy a used ECU from ebay.uk (since you are overseas) & swap them out. I seriously doubt the naked eye could detect any problem in the board, they are very high tech & everything is micro organized, even if you did find it, fixing it would be nearly impossible even if you had the tools/knowledge/equiptment, sounds like the ECU itself may have been a Manuf. defect if that is the real problem. I have worked in electronics all my working life, I do understand what you say but state of the art honda or most auto electric are not, it's really old hat for me and the new stuff - well you'd be amazed what I have repaired before, anyway thanks for the eplies guys and correct me if I'm wrong, you cannot just buy an ecu for the bird - you need the matching ingnition assemby also Dont know if it was mentioned already, but your best bet would be to buy a used ECU from ebay.uk (since you are overseas) & swap them out.

    ECU

    basically I believe I have a fault in the ecu, if what you say is true then I agree there would be no point in opening it, I know the ecu in a car is a bolt togeher metal box, i did some work on mine a few years back.........read my thread on the knock sensor

    ECU

    if so can you tell me what you found I am planning to open mine by cutting round the plastic at the end where the connectors are and hopefully slide the circuit board out. any help apprieciated
  5. I have HID low and high and if I have my low beam on when pressing te starter nothing happens
  6. Fixed so far so good and if it comes back at least I know the area of the problem - what did I do ? turned the ECU upside down, so wires and connections are laying a different way as I suspected this is not a knock sensor problem as I checked and double checked the wiring, it is another undetermined signal from another sensor that is required for the KS to operate correctly.
  7. well something strange happened Went for a ride yesterday and instead of the usual FI light on after 3000 revs - it stayed off and it stayed off for 30 miles, I gave it loads and it still stayed off, thinking this can't be the bulb must be faulty I switched off and on and the light was working fine, stopped the bike at the hospital for about 4 hours came back out rode for 2 minutes and on it comes again and has been the same since anyone manage to get the info I requested about the KS test ?
  8. Afaulty KS must put the engine in safe mode as it cannot function safely, the KS allows the ECU to maintain ignition advance right on the edge of performance at all rev levels and throttle positions, if the ECU is not getting a correct KS signal it has know way of knowing what the setting should be so it retards the ignition to a safe level, this results in poor performance, the KS is a fundamental component of all FI systems, the checks you mention I have already performed All I need to know is the test routine the ECU performs to determine if the KS is good or bad, I do know that the test occurs at 3000revs but that's it, TBH I suspect that my ECU is faulty.

    Water leak

    i'm loosing water/coolant, can't see anything externally, are there some common leaks that develope on the bird also where is the point to apply pressure to check
  10. Source (Good Read) it is my understanding there are 2 different types Od KS, the one on the Bird does not have a ballast resistor, it reads OC on a meter, could be wrong but I know mine reads OC also as I mentioned before a guy with the same problem as me replaced the KS and it didn't fix it
  11. many many many thanks guys, you have know idea how much better I feel right now, maybe if I can get this intense headache to lift I might even go out today cheers and the best of luck with your inquiries
  12. does anyone here own a honda ? does anyone here have any contact with a honda dealer does anyone here want to offer a little of their time to help another BB owner (oh and I'm not from the US but that shouldn't make a difference) does anyone here have the ability to go to a honda dealer and ask them to either supply a copy or request from honda the technical details of the knock sensor testing and error process does anyone here think this may be of value to everyone does anyone here think (like I do) that this is about to become a cronic problem with 99 Birds does anyone here think that helping someone that lives in Thailand is out of the question does anyone here think that this is the best BB community on the net does anybody care :-) I used to be a member of a car forum in te UK, we would often get people from around the world dropping in looking for help, I was actually the technical expert as I nationally raced the car, I did all the technical modification the the engine and running gear and many people followed my lead. I was always willing to go out of my way to help others no matter where they resided 99.9% of the time people praised the level of help and support they recieved, I even had the main dealers in my local area contact me several times for help with problems. If I was living at home I would not be requesting anything from anyone here, in fact I would most likely become a technical expert on the FI Bird to everyones benefit Now I know some people may read this thread and say FU (feel free to do so), others may actually find it within themselves to offer assistance Now off the the hospital on my sick bird for an MRI scan and some other tests. cheers
  13. I have posted on the other thread.
  14. Stan, unless I've been living in a dreamland, you are out to lunch. A piezo sensor is a voltage generator, not a moving contact. It generates voltage by mechanical stress on the quartz crystal, really it is just a microphone set to emphasize mechanical response. Its conductance will be zero. And it is also resonant, so it is very frequency selective. There is another style sensor used on some cars which is not resonant, but I digress. yep, one wire generates voltage, retards timing. Reading skills still growing. Looks like if disconected should not fault or retard,,,,I wonder, garkness??? It is my understanding On a stock Bird fault 25 will flag at 3000revs if you disconnect the KS, I wish I could get my hands on one to try, the reason I won't just buy one is because someone else with same problem as me replaced the KS and it made no difference to the fault condition, this means it is either the (1) ECU or (2) some other fault that makes the expected normal KS readings appear wrong and the ECU flags a fault condition, my choice is number 2, in order to progress this further I need the precise test parameters so that I can test every on of them, as the ECU relys on Throttle position - revs - timing - mixture etc etc, I suspect a fault with any of these other things could be interpreted by the ECU as KS Thoughts 1. Throttle position - this has its own diagnostic so is unlickly to be at fault, not ruled out 100% 2. Revs - can't see how this could be at fault, the engine revs up and the rev counter shows it. 3. Timing - ECU controls the ignition timing based on almost every variable on the engine, retards when it gets Knock signal from Knock sensor, I can't see what could mechanically move or slip that would cause the timing to slip out of tolerence although I'm not ruling out the possibility, if the ECU is testing the Knock sensor and it thinks the timing is in a certain condition (retarded or advanced) when it isn't, it could easily interpret this as a KS fault, can't see how this timing error could occur though but I'm open to suggestions. 4. Mixture - again controled via the ECU dependent on revs - throttle - temp - ecu map, ECU controls the injectors directly, can't see how there could be a failure here, only thing maybe would be fuel pressure which could cause the mixture to be wrong, this again could cause the KS to produce invalid readings when being tested, running rich will surpress knock - lean will encourage it. when the ECU shows a fault condition it is indicating that the indicated component is not working correctly There is an awfull lot of testing required here if my overview is correct, what would be extremely helpful is some technical data from honda that explains the actual KS test in detail, on the other hand I could be way off base ................................ http://www.cbr1100xx.org/forums/index.php?showtopic=46100 I also think that this is going to be a common problem amongst early FI birds, I now know of 3, perhaps over the next 12 months that figure could increase. you guys have no idea how frustrating this whole thing is for me, every time I get on my bike (every day) after about 2 mins the FI light comes on my power drops 30% and my fuel consumption drops, I have a workshop I use but it is a general none specialist place, they can strip an engine and build blindfolded but when it comes to stuff like this they are relying on me to tell them what to do, there is also a language barrier, thailand doesn have honda dealers but only for small 100cc bikes. I have no doubt if I was in the states or UK I could have this sorted in days. I am also going through an illness right now which doesn't help either, my one great release and pleasure -my bird is sick too what I am going to do is take the sensor to a workshop where they have a scope and see at least if it is outputting a signal when tapped, difficult here in Thailand trying to explain though..
  15. Anyone have any idea how I could get the full technical specs for the Knock Sensor - specifically how the fault detection system works, what the ecu expects to see and what type of failures it will detect with a full technical description, pretty sure it will be part of the technical description for the ECU any help apprieciated access to a honda dealer (which I dont have) might be a solution, I'm pretty sure they can get info like that if they needed it.
