HELP AGAIN! I'm having problems with the speedo

[kornboy119]

Hi again,

I have just recently bought my Supra, and the previous owner has just replaced the face of the speedo to read into MPH, but the car is still reading in KMH. Could anyone suggest to me the best option for getting the correct speedo reading, i.e. changing the entire speedo clock, or is there a chip you can get. If any of the these are needed to be done where could I get the parts from.

Cheers Dan

Here you go. If you want to remove the top speed limiter get the combined unit. Here http://www.thor-racing.co.uk/DSC+TSD_Combined-DSC+TSD.asp

EDIT : Not really a ICE question mate. :)

I agree with smarty, a Thor speed converter is definitely your best bet.

Incidentally, what do you mean by "the car is still reading in KPH"? If the speedo dial has been changed, then the car speedo will (if the new dial face isn't bodged) be reading in MPH. The main difference is that your speedo's digits probably stop at about 120MPH, whereas if you get the converter, it can read up to 180MPH.

Not trying to put you off getting a converter unit: there are electrical systems in the supe (e.g. progressive power steering) that rely on a proper speed signal. Just want to make sure you're not concerned about the odometer still counting up in kilometres: this is a separate issue which can be fixed if you want, but a speed converter alone won't do it. Ask or do a search if you want more details about that.

the thing is that just the face has been changed, which means that the clock is till in KMH, but the face shows MPH. So when I'm doing 80MPH on the clock I am actually doing about 50MPH

many thanks for your replies

That would only be caused by someone simply changing the "KPH" sticker in the speedo to a "MPH" sticker! If that's what's happened, then the previous owner did a completely pointless (if very minor) modification!

Best thing to do is get a speed converter from Thor. I recommend Thor because their ones sort out the other electrical goodies I was talking about.

All the instructions are on the site for fitting these devices too. Very simple too do.

What is the top speed on the face of your speedo at the moment Kornboy?

[kornboy119]

it is showing 0-180mph. but it is reading as if there is a 0-180kmh
