Somebody correct me if I'm wrong, but you can't put a used cluster on because the VIN and mileage are locked to the first bike it was installed on. | ||

Correct ratbuell, only good for parts, i.e. screen | ||

Damn damn damn | ||

I'm not so sure. I think if you use a race ECM you might be able to get away with it... I don't know this for sure, but I'm not sure how the cluster could otherwise know.. | ||
| Ratbuell |
Because the cluster and the ECM use bi-directional communication. The ECM can be changed from bike to bike, but once the cluster gets a VIN locked in...it's in to stay. | ||
| Jdugger |
> but once the cluster gets a VIN locked in Again, where's it getting the VIN? If I put a race ECM on a bike, the cluster just goes along being it's happy self thinking it's on the original bike it paired with, right? So, other than the mileage being wrong, I could quite easily move clusters around bikes... (I think...) | ||

Interetesting theory jjudder ! I'm thinking your right. Who has 2 1125's and a race ECM they can test this theory ? | ||

Seems this could be answered by checking the service manual. | ||

The FSM says once married(30 min countdown) and the IC is paired for life. ECMs can be swapped anytime. I have read of(anectdotal - 3rd party hearsay) people using a used IC. The bike ran fine but had the old bike's VIN and mileage.... as I said, hearsay. Pony up the bucks for a new one. Don't get an 08 IC, you'll lose the gear indicator. Zack | ||

It's BI-DIRECTIONAL. That means, both the cluster and the ECM store the VIN and the mileage. A new piece takes information from the old piece on first installation. A cluster is always dominant if both pieces are new. If a new ECM is put in, it will take the information from the cluster. Once a cluster gets information from an ECM the FIRST TIME....it stays in the cluster. It's locked. Like Zac said, there's a countdown. It gives a tech 30 minutes to troubleshoot function before locking that cluster to the VIN, that way a shop can have a "known good" cluster for testing. Once a cluster has a VIN, it has that VIN for life. I'm not sure what function is limited (if any) by using a pre-locked cluster on the "wrong" bike. Not sure what would happen to the mileage, VIN data, trouble codes, or if it would even work. You might just get ERROR. I don't know. | ||

Rat, So to OP's original plan, we still don't know if there's a reason he can't do this. The pairing and behavior of the IC is somewhat irrelevant to whether or not he could find a used one and make do with it. I would say if it comes time to sell the bike it could be a real issue (incorrect mileage, etc.), but if he's just trying to get the thing ridable, I'm gonna bet, in particular if he uses a race ecm, he can buy a used cluster. Based on the wiring of my race bike, I'm pretty confident in suggesting the only items on the bike aware of the vin are the ECM and IC. So, I see no reason you couldn't move them around at will, mileage readout accuracy being off, of course. There's nothing else and no wires on the bike capable of determining motor or chassis VIN that I'm aware of. My guess is the VIN is totally irrelevant to the operation of the IC, as long as it's using a race ecm which ignores the pairing data. If this is a track bike, or even a street bike as long as there's never an intention to sell or retitle it, I don't know of a technical issue with using a used cluster + race ecm. So, it might be a solution for a cost-sensitive rider... | ||

But a mismatched set could cause error codes, CEL, or flat-out running issues if its in the software that they have to "play nicely" in order for the bike to behave. It could be a legality issue, so people don't start swapping in low-mile clusters. I am certain there will be SOME sort of error present in this case, but I have no idea what difference it could make to ridability. Hell, it could get a "Danger, Will Robinson" and shut the whole thing down for all I know. It depends on how they wrote the software, and what kind of "mismatch tolerance" is in there. Will it say "eh, it's wrong, oh well" and go on with life as we know it? Or will it decide "ain't no way I'm gonna let you do THIS" and flip the big OFF switch in the software? I just don't know. I do know the manuals do NOT recommend doing this sort of thing, but they don't get into why. | ||

So buy the cluster and ECM both from a crashed bike... | ||

I think an IC from a wreck would function, just have the wrong VIN/mileage info stored. Make SURE it's from the right year/model - don't get an IC for a 2010 CR if you have an 09, R/CR is different too... You will get the "flash" for the donor bike, not yours, etc. Registration nightmare, I hear some tracks are checking VIN too. Physical and electronic numbers won't match. Never had this with analog stuff... change a speedo, no biggie | ||

> Make SURE it's from the right year/model Do you think it would really matter? Might mess up the speedo or gear detector, sure, but I bet the bike still runs correctly. What are you thinking would be off? > You will get the "flash" for the donor bike, not yours, etc. For the IC or for the motor? I'll bet the map and engine configuration still comes out of the ECM. > Registration nightmare, I hear some tracks are checking VIN too. > Physical and electronic numbers won't match. The big issue, at least here in Texas, is the mileage is off. That's going to cause an odometer disclosure problem if you ever go to sell or re-title the bike. Year-to-year registration won't be an issue at all. As for the physical vs electronic... how would anyone check it? Only a dealer could get at that data, and no one at a racetrack or service station has the HD equipment to do it. In the CMRA, we do register our VIN numbers, but it's so ordinary for race bikes to have mis-matched motors, frames and other parts, what they actually care about is you having any kind of provenance demonstrating the origin of the parts and that they aren't reported stolen. In other words, if I show up with a bike with a cluster, motor and chassis all from different bikes, that would be totally commonplace. They are race bikes, after all... we wad stuff up all the time. It's far from a perfect solution, I agree, but I can totally see the legitimate use of a used cluster, and it's hard for me to understand how swapping them around track/race bikes cause a functional problem given my experience with them to date. My race bike has an 08 chassis, unmarked (no vin) 09 motor, "08" race ecm, and 09 cluster, btw. | ||

Guard Rail - are you wanting the cluster only because of the LFL + CEL issue? If that's the only reason then there is no harm in running it as is. The "Low Fuel System Error" should have no effect on any of the running parameters that determine injector pulse width or ignition timing. Mine is going in on Saturday for a new cluster, but if mine wasn't under warrantee I personally wouldn't spend the out of pocket money for it. | ||

I'm on my way to bike week down Myrtle beach so I needed her running well. I sent her to the shop and the coolent light came on as well while they were unloading. All fluids checked out fine. They told me it's the cluster is going bad. I'm covered with Warrenty. But there on back order. They managed to find one new in Cali so I told them overnight it to me. Good luck with yours S21125r. | ||

Not mine, but if your still looking http://milwaukee.craigslist.org/mcy/2385003444.htm l | ||

Ic came in got installed and then they found out the sensor in the fuel pump is bad. No so much the pump, just the sensor inside the pump. So I can still ride it right??? I've got a Myrtle beach trip to got on. |
