Maverik Posted November 18, 2010 Share Posted November 18, 2010 Hi, found a thread on here about the TD5 instrument conversion, and to get the Speedo head to match with the old anologue one, you can get it sent away to be adjusted. I got in contact with "digidash" as I belive Ralph and a few others have used and the guy has charged me 120 squid for the honour... Has anyone had experience using any other company to get speedo adjusted at all? Cheers Mav Quote Link to comment Share on other sites More sharing options...
L19MUD Posted November 18, 2010 Share Posted November 18, 2010 Sorry to Hijack I am also interested in this as I have been running mine on the mileage of the new head. It only cost me £100 for the whole conversion so I'm also reluctant to spend £120 just to increase my mileage! Quote Link to comment Share on other sites More sharing options...
Maverik Posted November 18, 2010 Author Share Posted November 18, 2010 I did have a crazy idea... Its digital so the speedo head must take a digital signal from the transducer. Now rather than re programming it, could you not just replicate that signal, I presume it works on some kind of pulse???? can you not just increase the frequency of that pulse and change the clock that way? Its like a virtual "drill" fitment as it where... Quote Link to comment Share on other sites More sharing options...
L19MUD Posted November 18, 2010 Share Posted November 18, 2010 That is an interesting idea - but how would you go about creating that pulse? I did consider the drill approach directly but i need to go from 45k miles to 170k miles. The time i calculated it would take to change is a scary number!

crwoody Posted November 18, 2010 Share Posted November 18, 2010 The pulse generator idea would work, a simple electronic pulse generator will do it, it could take some time though, I don't know the maximum frequency that it could run at, but there is a limit. If you want to increase the mileage a bit it wouldn't be too bad, but to reduce it you'd have to run it all the way up to 999'999 and start again.

I have to think about it a bit more, but yeah I agree there will be a limit to the input frequency... another thought, could I modify an indicator flasher unit to give me a pulse... although I'm guessing there will also be a limit to what i could get the relay to switch too, but in theory, if there isn't any fancy elctrics in the transducer... I fear there might be though. Hmmm, but if you wanted to go all the way to 99999 what happens when you get there? I guess it could just lock at that number?

Cheers Mav crikey, that's gone up, almost double what mine cost to have the mileage total reset & it included post both there & back to Cornwall. I'm sure Porny on here said he could do this job too.

crclifford Posted November 19, 2010 Share Posted November 19, 2010 When i got mine done by Digidash, he was going to charge me £120 to come to Chatham and do my speedo. I went to him and he did it for £90. Not sure what he would charge for you to send it to him. Chris Quote Link to comment Share on other sites More sharing options...
