David P Posted March 23, 2011 Share Posted March 23, 2011 The best way is to simply fit a mph speedometer. The recorded km can be converted to m by specialist but don't have details. Quote Link to comment Share on other sites More sharing options...
TRD DAN Posted March 23, 2011 Author Share Posted March 23, 2011 ah right cheers dude , so can you literally but tt6 clocks and swap them over and then it will read in mph and miles ? cheers dan Quote Link to comment Share on other sites More sharing options...
David P Posted March 23, 2011 Share Posted March 23, 2011 Plug and play, you get 180mph and 300kph display and is compatible with active spoiler and cruise functions. I really don't know why folks dick about with converters that dick about and cost more than a real one! Quote Link to comment Share on other sites More sharing options...
3LL Posted March 23, 2011 Share Posted March 23, 2011 Thor dont do these any more but if you speak to Dan at sumo power they have some in stock for the supra.. These convertors come in handy if you want to de restrict a j spec as well as do the speedo conversion Quote Link to comment Share on other sites More sharing options...

I really don't know why folks $#@! about with converters that $#@! about and cost more than a real one! You would still need a converter, the ECU would be sending a KPH feed to the clocks so the mph would actually be the kph and the kph would not be anything. You need the converter there to give the correct reading whatever clock you have on the end. Quote Link to comment Share on other sites More sharing options...

stevie_b Posted March 24, 2011 Share Posted March 24, 2011 You would still need a converter, the ECU would be sending a KPH feed to the clocks so the mph would actually be the kph and the kph would not be anything. You need the converter there to give the correct reading whatever clock you have on the end. The speed sensor sends a pulsed signal to the speedo clock. This signal represents the number of hub revolutions per second, not mph, kph or anything like that. Presumably a UK car would have a speedo that decodes this "revs per second" signal into mph not kph. The speedo then passes the signal to the odometer unit which uses it to keep a running total of distance travelled. There is a modification that can be made to the odo unit that means it counts in miles, not kilometres (but as David said, this would give a total of a mixture of miles and kms unless the count-so-far was adjusted). The ECU then receives the signal from the odo, and uses it to control things like the top speed limit, Progressive Power Steering, possibly the active spoiler etc etc. I think David's idea would work (maybe he's done it already?) if a UK speedo cluster was used. The odometer modification is optional: if you don't do it the odo will continue to count in kms. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted March 24, 2011 Share Posted March 24, 2011 anyone else shed any light on whats best ? If I were doing it I'd see if I could get hold of a UK speedo cluster. Failing that, see if you can get hold of a Thor one converter. There are other converters around but no others that I've used. Quote Link to comment Share on other sites More sharing options...

That's a great explanation, stevie! so if I understand it right, i don't need any converter if I just install a MPH speedo clock instead of the Jspec Kph speedo. - and thats it? the thing is that i purchased a jspec supra which was driven in the UK and has now a OEM MPH tach. (must have been installed in the UK during the time it was driven there) so if I now want to go back to KPH i just have to install a KPH speedo clock? what if I install a TRD 320 KPH speedo clock? does that work as the OEM JSPEC tach did just count until 180 KPH...... sorry for my questions but I'm a newby when it comes to these things - here in austria nobody got ever in touch with these things....

stevie_b Posted April 26, 2011 Share Posted April 26, 2011 Ask away Herbert, that's what this forum is for. That's a great explanation, stevie! so if I understand it right, i don't need any converter if I just install a MPH speedo clock instead of the Jspec Kph speedo. - and thats it? Quite possibly. I've never tried it like that because I've never had a UK speedo clock, but logically it could/should work. the thing is that i purchased a jspec supra which was driven in the UK and has now a OEM MPH tach. (must have been installed in the UK during the time it was driven there) so if I now want to go back to KPH i just have to install a KPH speedo clock? Yes, probably. what if I install a TRD 320 KPH speedo clock? does that work as the OEM JSPEC tach did just count until 180 KPH...... The TRD speedo clock will probably work as you want (again, no guarantees because I've never used one). Quote Link to comment Share on other sites More sharing options...
