a98pmalcolm Posted April 23, 2012 Share Posted April 23, 2012 Hay guys ans girls. I took out my mileage display for some dash work and noticed there was also he miles in the screen. Its displaying the KM at the moment. Is there any way to convert it to show the Miles instead? Thanks Paul http://img812.imageshack.us/img812/9205/20120423211554.jpg Quote Link to comment Share on other sites More sharing options...
Andy Blyth Posted April 23, 2012 Share Posted April 23, 2012 Here's a how-to with an easy way and a hard way: http://homepage.ntlworld.com/peter.betts/supra/TechTips/odometer.htm I did the hard way; It's pretty fiddly to do but not impossible if you're comfortable with soldering.

Supra Kong Posted April 23, 2012 Share Posted April 23, 2012 Can you make this work on the odometer only? Ie convert to miles? As i have a speedo dials which are already converted.... Basically my speedo is reading mph and the odometer is in km.... Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 23, 2012 Share Posted April 23, 2012 Can you make this work on the odometer only? Yes, should be no different to what Pete Betts says in his how-to. When someone does the entire km -> miles conversion (i.e. speedo *and* odo), the speedo and odo are separate parts of the conversion, so it's just like you've done half of it already.

If the odometer increases by one for every km now, it will still do the same after the mod. The only change that this makes is to turn off the little "km" light at the right of the display and turn on the "MILES" light.

a98pmalcolm Posted April 23, 2012 Author Share Posted April 23, 2012 My speedo shows MPH and the odo is counting in miles since the car came into the UK Quote Link to comment Share on other sites More sharing options...

I get ya, but i'd be running it through a converter box, but i guess without converting the speedo? Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 24, 2012 Share Posted April 24, 2012 Unless you've got a UK car, your car must have a converter to be able to show speed in mph. This converter scales back the speed signal by 5/8 to go from kph to mph. By using this scaled-back signal as input to the odometer (pin 5, probably a purple wire), your odo would count up in miles.

stevie_b Posted April 24, 2012 Share Posted April 24, 2012 PS note that converting your odo to count up in miles will leave its display as a mixture of km and miles. If that doesn't bother you then fine, it's a personal pet hate of mine. Quote Link to comment Share on other sites More sharing options...
Thomas.B Posted April 24, 2012 Share Posted April 24, 2012 Is the TRL speed converter the same in principle as the rest? It seems abit to easy to convert back, is it just to reassemble the speed sensor cable to the ODO and Speedo? And the re-transmitted speed signal to the blue and all should work fine again? Are these easy to reach from just removing the cluster? Quote Link to comment Share on other sites More sharing options...
TubbyTwo Posted April 24, 2012 Share Posted April 24, 2012 Does the Thor converter/delimter enable the odo display to count up in miles? Ignore that it does: Additionally, the vehicle odometer will now increment in miles. http://www.thor-racing.co.uk/Electronic_Speedo_Convert-THOR00497.asp Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 24, 2012 Share Posted April 24, 2012 ThomasB: yes, that's basically all you need to do. Yes, they're usually easy to reach from just removing the dash fascia (only need the central part really, but to get that off the other fascia bits need to come off too.

Thanks for the help m8! Will do this tonight One question though, are the cable colours in the picture accurate? Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 24, 2012 Share Posted April 24, 2012 I *think* the cable colours are accurate, but not 100% sure of it. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted April 24, 2012 Author Share Posted April 24, 2012 When I bought mu Supra it had a converter fitted so its been counting up in miles since I have been driving it in the UK. There is a mixture of miles and KM on my display. I was hoping of a way that by making the miles glow and not the KM it would also change the display. So it came into the UK with 109.000 KM so just under 68.000 miles. Its now displaying 138.000 KM so I've done 29.000 miles since I'v owned it. It would be great If I could get the display to show 97,000 miles Does anyone know of any services ant were or If I could so this myself? Thanks Quote Link to comment Share on other sites More sharing options...
TubbyTwo Posted April 24, 2012 Share Posted April 24, 2012 Interesting point, curious to know the answer as well. I assume there are companies but wouldnt this be seen as Clocking the car? Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 24, 2012 Share Posted April 24, 2012 It kind of is clocking the car, but there are I believe reputable companies out there who can do it. Best ask the traders on here I think. I think you get a certificate to say when it was done, what the "before" number was and what the "after" number was. The certificate (or receipt or whatever) is hardly worth the paper it's written on, but it does provide some documented evidence of what's happened. The hassle of this is the main reason why I left my odo to count up in kms even though my speedo reads in mph. Quote Link to comment Share on other sites More sharing options...

Yes, they're usually easy to reach from just removing the dash fascia (only need the central part really, but to get that off the other fascia bits need to come off too. Well, it was easy enough. The guy that had done the convertion was "nice" enough to leave about 0.1mm of old cable left in the connector... I put the 2 cables back together behind the odo but it still shows "miles" Guessing this is because they have cut the blue/red cable together with the cable going from the converter. Didnt have anymore time to get the whole cluster off. But will simply take the whole converter off and get a new km/h speedo Quote Link to comment Share on other sites More sharing options...
Thomas.B Posted April 26, 2012 Share Posted April 26, 2012 Ok so Now it's all showing in km again. Question: I have left the pink ECU cable cut and now my engine light is showing... guessing this is why? Can I loop it somehow without hooking up the converter? cheers Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 27, 2012 Share Posted April 27, 2012 (From my PM): You'd need to fit a top speed delimiter to the car to delimit it. There's no other sensible way. It's possible that the speed converter you've just removed also has a delimiter built into it. Was yours a Thor converter? I think those ones say on the box whether they include a delimiter or not. If yours does have a delimiter built in, you jsut need to re-attach the 12v (red) and 0v (black) wires, and the delimiter output wire (yellow). Failing this, connect odometer pin 6 (see the Thor diagram) to the ECU pink wire: this will leave the car speed-limited again. You get the engine light when the pink ECU cable isn't connected to anything because that's the ECU's main (only?) speed input. When this is cut, the ECU doesn't know what speed the car is doing and throws error code 42 (faulty speed sensor). Quote Link to comment Share on other sites More sharing options...
