Davidv Posted August 23, 2015 Report Share Posted August 23, 2015 (edited) Hi,Not strictly an ECU related question, but I would like to have a tinker with traction control etc which requires a non driven wheel speed signal.My car is from 1983 so it does not have any factory wheel speed sensors, and I've fitted bigger brakes to the front of it which take up just about every iota of space in between the wheel and the hub/strut.So I dont really have any room for retrofitting an ABS ring type setup from another car.I was wondering if anyone's had any creative solutions for a similar problem?What sort of resolution on wheel speed do you need, would something like 4 pickups per wheel rotation be enough? Or 10/20/30/etc? More the merrier?Has anyone tried something like reading a signal from the edge of a wheel? Maybe an optical sensor or something... Although dust etc would cause problems.Any suggestions appreciated! Edited August 23, 2015 by Davidv Quote Link to comment Share on other sites More sharing options...
Simon Posted August 25, 2015 Report Share Posted August 25, 2015 Have a look at some of the setups the rally guys use for the distance meters.4-8 pulses would be mint. Quote Link to comment Share on other sites More sharing options...

mapper Posted August 26, 2015 Report Share Posted August 26, 2015 Can you elaborate that? Do you measure rpm at gearbox? any links to such sensors? Quote Link to comment Share on other sites More sharing options...
Simon Posted August 27, 2015 Report Share Posted August 27, 2015 There are a number of brands that make distance meters for rally car application these often use wheel speed inputs from sensors that can pick up the back of wheel studs on the hub.
