I recently had a diff gear change to 3.73 from 3.46 and the bloke who did it for me told me that it would not affect the speedo because the reading come off all four ABS sensors on each wheel and then average out across the four speeds. Pretty cool I thought. Link to comment Share on other sites More sharing options...

Under normal conditions, they don't really do this until you go over 120 km/h. In the Turbo, I could drive at 120 km/h no problem and no warning lights. In the Focus, however, I can be doing 120 and there are warning lights all over the place. Is it possible that the speedos on the Turbo are calibrated to deliberately over-estimate your speed. Its similar in normal traffic too - in the T I could sit on 70 and cars are going past me, but in the Focus its the other way around.Anyone bothered to get theirs properly tested and calibrated? Was it out?Originally these signs were installed and showed your precise speed, however as everyone tried to get the highest speed they could it defeated there intended purpose. So now and for some years now they simply tell you that you are over the speed limit and reinforce the applicable speed limit.Another brilliant idea by the RTA.I.B.

Slammer Member 81 Member For: 17y 8m 3d Gender: Male Location: Motherland Posted 20/03/08 04:55 AM Share Posted 20/03/08 04:55 AM (edited) just got off the phone with a local ford dealer and he said that those digital read outs are ONLY for the police and are illegal. If you can get caught with them you can get defected for it. Any news on this Edited 20/03/08 04:57 AM by Slammer Link to comment Share on other sites More sharing options...
