Any of you guys changed a US C6 cluster to CAN?
I just bought a 2009 Z06 and I would like to change the speedo from mph to kph. Cost? Difficulty?
Thanks,
John

I have an 08 Z06. I just change the computer to kph. It only makes a difference when you run out of speedometer at the drag strip or track. The Headsup keeps going though. Red line in 3rd is about 200 kph and about 240 kph in 4th BTW.

Example - say you are going 100 kph
Your speedo needle would be right at the midpoint of the 0 to 200 scale - a reading of 100.
Now you pasted the 0 to 300 scale on yourt speedo and once again are going 100 kph so the needle is still at the midpoint of the scale, expect the new midpoint reads 150. so now your speedo says you are going 150 when you are actually only going 100.
Am I missing something here??

It is a US car and I pasted the yellow kph faces on.
Does this solution make sense?? I'm not sure it does - you are pasting a metric dial which goes from 0 to 300 over the original dial which goes from 0 to 200, but the speedo doesn't know you have a different dial pasted over the OEM one and would still give you the original speed except you would now be reading a higher speed than you are actually going.

So you're saying by just overlaying the new metric face place, your speedo recalibrated to know that the increments are shorter? So when you buried the needle to 200km before it was at the bottom and now it's not?

Have not done mine by these guys in Whitby were the GM Authorized AC Delco/OEM cluster place. They quoted me $500 last year and apparently have done lots of them.

I did my '07 Z06 last year. US Speedo is awesome. They had a 300kph cluster in stock, programmed the mileage and even bought my 200mph unit back.
Give them a call very easy to deal with.

IMHO, there are two downsides to this approach. The first is when going to the US you would no longer be able to see the speedo gauge read in mph. The second is that the HUD would still display in mph, which is only a problem when driving in Canada.
i don't think you need to be looking at the gauges at over 200 kph

I would say yes, you are missing something. Using the overlay dial you would leave the computer displaying in mph and not set it to display metric. Thus in your example, traveling at 100 kph the computer woould put the needle at the 62 mph position, but the overlay (overtop of the 62 mph) would indicate 100 kph.

Problem is that 200 MPH equals 322 KPH so the 200 MPH and 300 KPH scales Chevy uses don't translate accurately.
Using our example: At 62 MPH the speedo needle position would be 62/200= 31% along the dial, and yet 100 KPH represents 33% of the dial travel. So there is some error being introduced by using the overlays.
Error, plus the fact that the speedo will never read MPH properly again, AND the HUD is reading in MPH are all big down-sides for me...

tomatoe tomato. 200/300. Nobody notices but you. Put your money into a more worth while upgrade imo. My car is US also, I just turn on the metric display and ordered a vararam with the cluster savings. Up to you tho, your car you have to be happy with it, just my 2 cents.

How much from US Speedo, if you don't mind my asking? (PM if you want). Somebody mentioned it's around ~$500 from Custone in Whitby. Curious if it's more cost-effective through US Speedo?
I don't like the 200 speedo either. It wouldn't be a big deal if I never hit it, but I do
. Now I AGREE that I shouldn't be LOOKING at it at that speed (which I don't, since I have the heads-up display) but sometimes passengers like to know how fast they're going (and it's not necessarily a great idea interrupting the driver at that speed to ask them exactly how fast you're going! 
).
I'd prefer the 300km/h Canadian cluster in my car too

Is this a direct drop in or does the computer need to be re-flashed? Since this is a stock GM part I wonder if we could get the "fleet discount" from someone like Kevin at Partstaxi or Gene at GMPartshouse? Might be worth looking into but then the odo would have to be set by someone approved by GM for warranty purposes....

The guys at US Speedo that do it all the time can change the cluster in 10 mins.
