edge Posted April 19, 2009 Share Posted April 19, 2009 Or it may be your speed delimiter as that looks like the same as the one i removed a while back. Is there a sticker on the other side of it? If so what does it say? Quote Link to comment Share on other sites More sharing options...

SteveR Posted April 19, 2009 Share Posted April 19, 2009 Where do the wires meet the loom(s), have you got any close up pics? Quote Link to comment Share on other sites More sharing options...
Soaruss Posted April 19, 2009 Author Share Posted April 19, 2009 I will have a better look tomorow but this is what I can remember. one wire, the one on the far right just under the wiper stalk is screwed to the back of the speedo. one wire goes into the blue plug that clips into the back of the speedo. A couple of wires go elsewhere. one wire (think its black) goes up behind the dash and over towards the glove box then down out of site.

Homer Posted April 19, 2009 Share Posted April 19, 2009 Yep, that'll be the convertor. Odd looking packaging, not seen one like that before. Quote Link to comment Share on other sites More sharing options...
Soaruss Posted April 22, 2009 Author Share Posted April 22, 2009 Heres how far out my speedo is. I have checked it against a sat nav. Sat nav reading 30mph My speedo 40mph Sat nav reading 40mph My speedo 52mph ish Sat nav reading 50mph My speedo 65mph Sat nav reading 60mph My speedo 77mph ish Sat nav reading 70mph My speedo 88mph ish Sat nav reading 80mph My speedo 100mph The wires from the converter are Blue goes to passenger footwell Red screwed to back of speedo Black screwed to back of speedo Yellow to blue plug in back of speedo Orange goes into loom If I replaced to converter would it wire up to same points as the one in now. Or could someone local to me wire it in for me ?? I'm not competant with electrics. Quote Link to comment Share on other sites More sharing options...

SteveR Posted April 22, 2009 Share Posted April 22, 2009 What does the speedo read when you are stationary; both with the engine running and when it's completely switched off (key removed)? It looks to me as though the needle has been moved, AND the speedo convertor is adding a % error as well. Quote Link to comment Share on other sites More sharing options...
SteveR Posted April 22, 2009 Share Posted April 22, 2009 Some basic calculations back up what I suggested: Take the real speed (sat nav), add 20% to it (the error from the speedo convertor) and then add a fixed 4mph (needle out of position) and you get the readings your speedo is displaying: Sat Nav | Speedo 30 | 40 40 | 52 50 | 64 60 | 76 70 | 88 80 | 100 Are your wheels massively different rolling circumference to stock? You'll need to adjust the speedo convertor either way - however not all are ajustable. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 22, 2009 Share Posted April 22, 2009 My car came with a speed converter like that. I think they're quite cheap (they don't adjust the PAS sensitivity properly), and my one didn't last very long before it croaked. I replaced it with a DSC+TSD from Thor: not cheap, but it does what it says on the tin, and does it well. It takes care of all speed-related anciliaries like PAS, active spoiler, etc. Quote Link to comment Share on other sites More sharing options...
SteveR Posted April 22, 2009 Share Posted April 22, 2009 I could help you fit a Thor unit if you get suck. You'd have to come to me though, and bring beer. Quote Link to comment Share on other sites More sharing options...
Carl Posted April 22, 2009 Share Posted April 22, 2009 Whilst we are talking about these. Often when I am sat at the traffic lights with foot on brake (autobox), my rev counter keeps flicking up and down by its self. Could this be a problem with the speedo converter?

SteveR Posted April 22, 2009 Share Posted April 22, 2009 Are Thor selling these units again? They stopped making them for ages. Dunno. I suspect they would if the demand was there (i.e. people ring up and ask for them). It's not hard or costly to them, just an EPROM, a plastic case for a few pence and some bits of wire. Failing that, someone on here was selling one a while ago, can't remember if it went or not. I'm not interesting in buying it but any interested parties can go hunting for it, of course.

Jay_vr6 Posted April 22, 2009 Share Posted April 22, 2009 I ordered a tsd from thor 4 weeks ago online and it turned up a couple of days later so i'm sure they are still selling them easy to install and good instructions. Quote Link to comment Share on other sites More sharing options...
