Speedo kph to mph conversion


jaw

Recommended Posts

Sorry in advance, as no doubt this would have been covered, but I cant find an answer that means anything to me!

 

Bear with me as I've basically no knowledge on doing this but:

 

How would I go about converting the speedo redout on a tt auto to mph? Anyone have any suggestions of parts etc?

 

I'm just generally worried about speed limits / cameras, with it being in kph, so would like that sorted asap!

 

I need a satnav anyway, and hopefully that will have a readout, but with acuracy (or a delay in updates at least) and a small read out, its not Ideal really..

 

I'm not too concerned about the odo being in kph as it's not something I'd use often, so if that would make the conversion easier, I'd go for it! I'd like to have a shot at this myself, so if anyone could point me in the direction of some helpfull links etc, that'd be great!

 

if its not a job for a noob, how much am I looking at for a pro to have a stab at it?

 

any help appreciated!! :)

Good advice from Jimmy above, also although the Odo will "convert" from recording Kilomretres to miles, the converter itself does not "change" the reading you see, so if you convert with the Odo showing 50,000 kilometres it starts totting up miles from that figure.

 

Both Thor and NCS will take your Odo and "reduce" the reading to its miles equivalent, but many folk just take a photo ofthe Odo at time of conversion and then use this to demonstrate total mileage if later selling the car.

 

Its also possible to change the Odo reading of "kilometres" to "miles" and if you get Thor/NCS to change the digit reading, they will usually do this as well. Costs about £100 for the figure-change and the Km/Miles change.

 

As I understand it Turbo Supras require 2 off converters to be fitted, one covering the speedo and the other covering the ancillaries(Phone either Thor or NSC....they are both very helpful in explaining what's needed.

Best regards

PS Do not under any circumstances go for the "cheap" Ebay converters....they ARE trouble!

i was not aware that Thor/NCS can change the readout so the figure you see is the figure the car has travelled in miles - that sounds awesome!
It does sound awesome, I don't think it does it that though. It just makes it start counting up in Miles from when it was fitted.

 

i was always worried that upon conversion you'd have a mixture of XXX km and XXX miles on top...
You would.

Just to clarify my post, if you fit the converter, it starts to rack up "miles" on top of your existing Kilometre figure.

 

If you send the Odo to Thor or NCS they will change the KM figure to the respective "Miles figure" for about £100 which, as I understand it, includes changing the circuit board on the Odo so that it shows the legend "Miles" in place of the legend "Kilometres".

 

The £100 is additional to the cost of the converter, which for turbo models, may require 2 of them. Best thing to do is phone either Thor or NCS, they are both excellent at giving advice.

There's a simple mod you can do yourself to change the legend to Miles.

Why might a turbo Supra need two DSCs ?

Edit, I've just re-read your first post in the is thread and see what you said about one DSC for the speedo and one for the other ancillaries. That's not right about the Thor DCS though. Only one is required.
