You were right on dot suspecting the ECM to be the cause.

So could the core processor be somehow enabled to send speed signal to the cluster, via ECM?

Yes. My solution #2 is spot on. I can have my core talk to the non-ABS ECM to get the speed, and then retransmit it as the message that the cluster needs (and I can do the kmh to MPH translation).

Kioshi · 10-20-2009, 12:08 AM

Nice.

I'm still a bit confused about the kmh to mph translation/conversion....

Ie: if i were driving 60 kmh looking at the cluster, it would be transmitted as 60 mph if to be clocked by a radar gun? If so, then i would not have any use of going beyond 120 kmh?

Thanks Scott.

Correct. If I translate it then when you are doing 60 MPH the pointer will be at the 60kmh line. It would mean that the pointer would never see the right side. I wonder if that's how it works when they get reflashed from kmh to MPH, or do they change the overlay to correct the scale?

Would this effect the rpm of the car then (relate correct rpms to engine speed), i guess i would just reach redline a lot sooner haha...

I can find the answer out tomorrow from Speedo, the place i will go to get my odometer flashed to correct mileage on my car currently...

Kioshi · 10-20-2009, 11:05 AM

CTScott - If it's too much trouble of translating kmh to mph, i wouldn't mind not having it done on the cluster. I kind of feel bad that I kind of reined on Lewis's cluster and had you work on mine before his, and his being the first priority...

Unless Lewis is okay w/ it, then yeah...

It would be a learning experience for me to adjust myself to kmh as well...so yeah I wouldn't mind not having it translated if its to much time consuming~

yarisugi · 10-20-2009, 12:16 AM

Just imagine the letters "mph" instead of "kmh" - the numbers on the speedo will be the same.
That way, whatever you see on your speedometer will be the mph reading. (if I understand correctly)

Lewis · 10-20-2009, 11:20 AM

ok with me Kioshi- we'll need to clone Scott- one genius is not enough!

CTScott · 10-20-2009, 11:34 AM

The kmh to MPH conversion is no big deal (and would allow a metric cluster to be used without reflashing). I also realized that if the cluster has lower mileage than your car, I can change the ODO with no problem (the cluster doesn't speed limit, so I can feed it max speed {255 kmh}) until it gets to the correct mileage). So this would mean that the clusters could be used without reflashing.

Many of these things which I am learning with Kioshi's cluster will have applicability to Lewis's cluster as well. Even though he has ABS, if he decides to sell, rather than use the cluster, the non-ABS cluster converter could come in handy.

Kioshi · 10-20-2009, 11:59 AM

From what i remember, the RS cluster has 6080 kilos on it. My USDM cluster has roughly about 27,980 miles...

That would save me a trip to Speedo to get the cluster reflashed. That'd be really nice if you could adjust the odometers to the correct ones on my cluster. If you could let me know before you get to that step, I can give you the exact or a higher estimated number that i have at that time...

True, you could sell multiple copies of the non-cluster converter unit to those wanting to swap in the future.

P.S. with your cluster converter, this is going to be all plug n play, correct? I dont want to be splicing wires and whatnot, esp that smal of a gauge wires..lol

On a second thought, I'd actually like to see the needle hit the other side..dont know why :)

Lewis - so true

Sounds good on the ODO piece.

As for plug and play, it will be fairly so. The module will have require four tap splices to existing wires. They can be done at the cluster or at the OBDII port.

I still have to sort out the indicator issues as well. For those I can do cuts and jumps on the circuit board so you don't have to swap any wires.

Your going to have to tell me how to do that, I've never tapped any wires into any other wires at all. I think the OBDII port would be easier, longer wires? Wires to the cluster seem very short and very little space to work with...

I think you can guide me on this later, when the cluster arrives to me...

Agreed. The cluster wires are as tight as banjo strings. there's a good amount of slack at the OBD port.

POORSHA · 10-20-2009, 01:16 PM

Maybe an obdII plug?

That would be an option, but since it's driving the speedometer, I'd want it more permanent.

Kioshi · 10-20-2009, 03:26 PM

If tapping wires into other wires is easier than what I'm making it seem in my head, I'd go for that route (waiting on Scott's instructions

). Techinically, I'd like to keep the OBD II port open for something like..scangauge in the future...and like Scott said, for speedometer, so it should be permanent..

I've soldered wires, thats about it, but that was on R/C cars w/ 12 gauge wires~

advocate · 10-21-2009, 01:34 AM

Do I see a swap occuring? And jesus james how many clusters do you have? If you have an extra one at the end of all this madness with a tach I'll probably buy it off you with the HIDs. Assuming I can pay off these damn seats in the next century

CTScott · 10-21-2009, 12:12 PM

Update on progress with the JDM one:

I can read the vehicle speed from the ECM and send it to the cluster, so the pointer does the correct thing. The issue I am having now is that I can not reliably get it to increment the odo. There are two extra bytes in the CAN message that thus far I can't make sense of (nor find any documentation for). I'll have to do some more watching of data from my 09 to try to make some sense of it.
