_Shane_ Posted June 20, 2008 Share Posted June 20, 2008 fitted my el glow dials today and as usual nothing ever goes according to plan. To cut a long story short when i was putting on the dials i couldnt get it on fully over the needle and then the speedo needle popped off, thought nothing of it and stuck it back on. Turned ignition on, speed reading 40mph and revs reading 3k. Removed the plastic cover, started the engine, took off the needles and put them back on , speed at 0 and revs at 0. Now car is reading 15mph more than what im actually doing Help please lads Cheers Quote Link to comment Share on other sites More sharing options...
Konrad Posted June 20, 2008 Share Posted June 20, 2008 Go on motorway, do 60 miles / hour steady with GPS on and put needle back - done. Quote Link to comment Share on other sites More sharing options...
_Shane_ Posted June 21, 2008 Author Share Posted June 21, 2008 thanks for that mate cruise control will help me out there to keep it steady Quote Link to comment Share on other sites More sharing options...
Dazzi Posted June 21, 2008 Share Posted June 21, 2008 I already said use your satnav/GPS in your other post Quote Link to comment Share on other sites More sharing options...
MrRalphMan Posted June 21, 2008 Share Posted June 21, 2008 I assume that just calibrates it for 60 MPH only? The rest of the range will still be out by a bit... More dangerously does it not mean slower speeds will indicate slower then real speed? Quote Link to comment Share on other sites More sharing options...
Pabs Posted June 21, 2008 Share Posted June 21, 2008 When I did my dials, I used my blitz boost controller as it had a speed reading too - so I got on Motorway, set cruise to an easy speed to do, and then put the needle on. I've checked through most of the speed range now and it's only 1-2mph out in places - which is fine PC Plod allows for 10% error in speedo anyway, doesn't he??

MrRalphMan Posted June 21, 2008 Share Posted June 21, 2008 Coolio, I just thought it might make the lower speeds worse. ie My speedo reads 10 to 12% fast. Real speed (Indicated speed) 30 (33) 50 (55) 70 (77) Moving the speedo at 70 (77) to 70 removes 7 MPH from the indicated speed. Take that off at 30 and it'll read 26 MPH. That's what I would have thought as you are not changing the ratio, just where the needle is. If that makes sense. Quote Link to comment Share on other sites More sharing options...
Rayman Posted June 21, 2008 Share Posted June 21, 2008 The way i did it was to put the needle on with it facing under the 0 say 15mph under the 0, so at -15mph then carefully bend/move it back over the needle rest with out it popping off. Then go check how accurate you was using one of those speed camera type things that tells you your speed is when you drive past it. Quote Link to comment Share on other sites More sharing options...
Konrad Posted June 21, 2008 Share Posted June 21, 2008 I did this on 4 cars till now, was putting needle at 80 miles/hour (because it easiest) - all speed is shown properly with 1 mile/hour + - through all the range. Quote Link to comment Share on other sites More sharing options...
Nicolai Posted October 29, 2008 Share Posted October 29, 2008 Sorry to bring this thread back up, but the previous owner of my supe changed to el glo dials and the needle popped off and he just put it back on. No is my question, how to I get the needle of again safely? Without the change to break something.. Many Thanks, Nicolai Quote Link to comment Share on other sites More sharing options...
