Hi all,
My Porsche bought from Great Britain has its OBC set to MPH...anyone knows how to set it back? Its a LHD drive from Germany, so the speedometer is in KM/H.

I dont thnk you can. I have never seen it on mine.

It must have left the factory with KM/h..and was changed in GB to Mph...Either it must be changed with the hammer or a trick with the control stick?

You will need to change the tacho for one in kph. There is no way of using the stalk or hammer to change it.

They come up on eBay now and again but you must make sure that it's the one you require. Turbo porsches have a boost pressure...mph/kph so there are 4 types I believe

I just bought one in mph

There are several market specific OBC tachs that handle the different combinations of kph, mph, liters, US gallons, Imperial gallons, degrees C and degrees F.

You just find the part number for the one you want (Porsche PET or your dealer), put a watch request on eBay and wait!

Cheers,

Jim

Holly Cow! I’m stupid……I thought that you gays where stubborn on the speedometer /OBC. I went down to my garage to take a photo off it…the OBC are located in the RPM-meter ( or what ever you call it)..and I completely understand the solution!´

Hallo Great Britain…Anyone that needs RPM meter with OBC for a Turbo in miles….and have one for trade in Km/h ??

who you calling gay there buster
