Kaan W Posted January 4, 2013 Share Posted January 4, 2013 Just a quick question regarding how the speedo works out the speed of the car is is done by the rear wheels or front wheels? Because if its the rear wheels then its not really that accurate if your loosing traction on the rear wheels. Sorry if this has been covered but i couldnt find a link to this information...

Guest BradD Posted January 4, 2013 Share Posted January 4, 2013 i think there is a speed sensor on the transmission box, so yes it's effectively the rear wheels. That's why you still register a speed on a dyno Quote Link to comment Share on other sites More sharing options...

Its just a made a video so I could accurately measure my 0-60 time but thats not gunno work if go by what the speedo reads... Quote Link to comment Share on other sites More sharing options...

You could use a GPS, most of them show your real speed as opposed to the higher registered speed on the dials, or if you have changed from the original tyre circumference Quote Link to comment Share on other sites More sharing options...

Probably be better off with a G-tech meter or simular? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 5, 2013 Share Posted January 5, 2013 Most aftermarket ECU's will log a dedicated wheel speed sensor, so you could assign a front one, assuming they stay on the ground at the launch. Quote Link to comment Share on other sites More sharing options...

If my front wheels were coming off the ground at launch then it wouldnt matter what my 0-60 time was Quote Link to comment Share on other sites More sharing options...
