David in Hampshire Posted April 1, 2014 Share Posted April 1, 2014 Hi Gang I've just imported an Impreza wagon. And I want to convert the speedo from KMH to MPH. Does anyone know how it's done? All the other forums talk about delimiting the engine, the ecu, the final drive on the gearbox and the clusters but noone really knows how. Any clues? Thanks DIH Quote Link to comment Share on other sites More sharing options...
Gambit Posted April 1, 2014 Share Posted April 1, 2014 Hi mate welcome to S.O.C Only people I have know thats done it used what you said about the Delimiter chip and used the white dial covers. Like these for example http://www.ebay.co.uk/itm/SUBARU-IMPREZA-LEGACY-SPEEDO-CONVERTER-DELIMITER-CHIP-/400060708263 http://www.ebay.co.uk/itm/WHITE-Imported-Subaru-Impreza-Replacement-Speedo-Dial-Kit-KmpH-MpH-0-180-/190691363701?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2c66174b75 other than that I'm not sure I've never done it myself. One of the other members might have done it before and be able to advise better :) Quote Link to comment Share on other sites More sharing options...
David in Hampshire Posted April 1, 2014 Author Share Posted April 1, 2014 I wonder if the chip resets the speedo reading? turns kph to mph, if you know what I mean? Thanks for getting back - i've emailed Keith, the bloke who supplies the delimiter chip - and i'm waiting on him. thanks did Quote Link to comment Share on other sites More sharing options...

David in Hampshire Posted April 4, 2014 Author Share Posted April 4, 2014 I'm not getting anywhere with this Impreza. It's a 1.5, built in 2006 and I need a speedo that clocks up and shows MPH because i've got to get through a VOSA inspection. Bloke on eBay was as much used as a !Removed! in a space suit. Any ideas?

Gambit Posted April 4, 2014 Share Posted April 4, 2014 I'd guess he just sells them then. Now I came across this might help a bit but is yank and I'm sure getting one off fleebay would be cheaper but might help Version 7 and 8 (MY 02-07) Signal In: Yellow -> Green (gearbox sensor side)Signal Out: Grey -> Green (loom side)12v+: Red -> WhiteGround: Black -> Brown http://www.iaperformance.com/product_info.php?products_id=2208 Quote Link to comment Share on other sites More sharing options...
bitman Posted April 4, 2014 Share Posted April 4, 2014 can't you not try to source a MPH dail at a breakers yard to replace the KM dail? or is my thought to simple 1 Quote Link to comment Share on other sites More sharing options...
Gambit Posted April 4, 2014 Share Posted April 4, 2014 Nice thinking mate doesn't work like that, that little I do know :( Quote Link to comment Share on other sites More sharing options...
Tlag Posted April 4, 2014 Share Posted April 4, 2014 All the JDM cars that I have seen have a little box wired in behind the gauge cluster. From memory, it's only two wires, one+ and one -. I have no idea how it works but it makes your speedo work in mph and not kph and it de limits the speed. In Japan they are limited to whatever 112mph works out to be in kph . The units about £15 last time I looked. Although I've just done a very quick eBay search and can't find any. My current car dosnt have one and still shows in kph. It's never been a bother at mot time. Quote Link to comment Share on other sites More sharing options...
