Ok i just got a good deal on a busa. It needs some work, but i didnt know it was to this extent. Ok im a newbie I have pretty good knowledge of what im doing, but i need some help
The cluster has some weird wiring issues. The tach idles at 3k, even though it is at normal rpms. the spedo is stuck on 110 whether the ignition is on or off. The engine temp is broken.
All this just seems like a cluster, but it misses and sputters at low rpms. once to mid-high it is fine. Sometimes it even backfired through the intake.
The bike is an 02. A couple owners before me put a 06 motor on it. Idk what the problem could be. I need help!
PLEASE!!!!!!!!

Taking into account everything you have provided and maybe trying to "see" through to what you maybe encountering; The Combination Meter (or gauge cluster to you) is made up of four "Stepping Motors" that operate the Speedometer, tachometer, fuel meter and the engine coolant temp meter. All meters will move to a full-scale immediately after the ignition switch is turned on to enable self-calibration. et al., from the service manual.
To reset - follow the full procedure below to hopefully gain a clear indicating meter.

If you have found that one or more 'Step Motor' is faulty (like the engine temp), you may be better served to replace the whole gauge cluster rather than to replenish the individual step motor itself - i.e., cost of individual v. total replacement.
Also, what I would do on the rest of the bike is remove all panels and give the bike a thorough pre-flight on all torque specs. As you go around all points, note where you find a lose bolt. You may just stumble on the lose fitting right away. If you need torque specs on specific areas, let me know.

:!: One other thing - before starting the re-calibration - Remove and inspect all prongs on the 'lead wire coupler'. Make sure you are getting a good solid connection and then re-insert. :!:

Ok thanks alot! I will do this procedure when i get off. :lol:
-
:wink: lemme know
-
Yea idk man. That spedo was stuck on 180 this time. It didnt move any. But as far as the engine temp goes, i played with the kill switch with the bike not running and it will go to reading where normal opperating temp, but when i flip the switch to on it goes all the way to the bottom again. And the bike is still running really bad. I think its worse now!
I appreciate the help. If anyone has and tips for me let me know please
-
Could be the ECU...
-
Is there any way to test it?
-
You could try one from another bike. Smithabusa or Petrik might know another way to do it...
-
ok thanks man. could that be the problem with the cluster? you think?
-
It might, if you can get your hands on another ECU you'll know for sure.
Ebay has a few for sale, or someone here might, could be someone here might lend you one also.
But before you go and spend money, talk to Petrik or Smithabusa, or someone they suggest. Those guys are doing a lot with the stock ECU.
Anyway, good luck and hope you find a cheap fix.

If you need a 185 speedo, I have one. 17,xxx miles. 150.00 TYD
I would check out the ECM first. Before bailing on the gauges.
-
Did you go through the check and reset with the above info on each step motor? :?
-
However, the gauges cannot cause the engine to run lethargic. :? did you run through every connection? I wonder if the tipover switch,,, no, ,that would kill or not kill :?
-
Yes i did a thorough inspection of all connectors and wires. all seemed good. Ima try and buy another ecu :cry: hopefully thats it
-
Whatever the problem is. It is to the point to where the injectors fuel fouled the plugs. Idk if this would help, but im am trying to give as much info as possible
-
Leave it till you get more info or an ecu. You could damage that engine.
-
if it has a power comander on it, bypass the timing part of the PC
-
:thumb: Good idea, didn't think of adders.
-
I could see how that could work, but i dont have a pc on it?
-
My vote is ecu, but I'm no expert. :lol:
-
ok i got some extra cash. ill buy one from someone on here and keep yall posted
thanks again for all the advice :wink:
-
b4 buying new parts,ohm out the pickup. you can access it under the tank by pulling apart a 2pin plug. it will cause your problem also.
so your not throwing a code at all?
you said has diffrent motor, has anyone messed with the cams? (has the valve cover been resealed)
-
hmm i dont see a 2 pin plug. could you suppy a pic of what its suppose to look at. and the valve cover seems to be sealed. cant see any leaks
-
Well now i dont have fire to the plugs? Idk what this could be. Would this all be linked. guages, running bad, now not firing from coil..?
-
You need someone that can troubleshoot with the bike in person, Bro. Do you have someone near you trust and that knows Hayabusa's?
Is it NOT throwing ANY codes at all on the gauge cluster? You know where to look, right? No codes at all? :? It honestly sounds like your ECM is having huge difficulties trying to figure out what is going on,,, if my PC was doing this,, I would be looking to do a 'Restart'. :?
-
Well i know a couple techs at various shops around, but nobody that has knowledge of hayabusas :cry:
-
The temp gauge will go to full hot when the engine kill switch is set to "off", that's completely normal.
If there was an engine swap, make sure the ECU and the sensors are correct. For example, the early Busas used a 16 bit ECU and a different sensor to run it. Later bikes (I think '02 and up) used a 32 bit ECU and had a different crank pickup. Make sure all the sensors are plugged in the correct places, there is at least one connector that can be plugged into the wrong sensor, I can't remember which 2 use the same connectors at the moment....
I'd also post this in the "All Motor" section, there are some very sharp people in that area who may be able to shed some light on your issue(s)

Well after messing with this and checking and rechecking everything, I decided to start with a whole new ecu ,wiring harness, coils, everything! Hopefully the problem is in there somewhere. It should be in next week so ill put it on and keep yall posted
-
Well just to let everyone know that the problem was somewhere in the wiring. It runs great now. Exept for the cluster is still messed up, so im thinking whatever messed up the wiring messed up the cluster too. :(.. So if anyone on here has one for sale, Could you hook me up with one. I have cash in hand!
Thanks again for all the help guys, Im a newbie here but I will def recommend this site!! :lol:
