D3N0 Posted September 25, 2013 Share Posted September 25, 2013 (edited) Ok so were taking wheel speed sensors here, I'd like to know how other's have gone about picking up their wheel speeds for devices in which use them for such toys like launch control (not the mickey mouse kind) and traction control.And before someone jumps up and says use the abs sensors from the front and back hubs. I would like to retain the abs or at least not interfere with the abs system.In other words is anyone else running two abs/wheels speed sensors per hub or corner. I'd just like to see how others have gone about this task.Driven wheel speed is taken obviously from the front and un-driven from the back.Also has anyone tried taking the driven wheel speeds from the gearbox through a sensor.Any shared info would be great.

Stu Posted September 25, 2013 Share Posted September 25, 2013 Could you setup an extra sensor using the abs trigger wheels and input that way? Quote Link to post Share on other sites
D3N0 Posted September 25, 2013 Author Share Posted September 25, 2013 Could you setup an extra sensor using the abs trigger wheels and input that way?That's what I'm currently doing, but wanted to see how others have done it. Where did you mount the sensor because I know there's only one hole for a abs sensor. Don't really want to attempt drill through cast iron to made another one. However I do mine.... I'll share some pics. Quote Link to post Share on other sites
yaristurbo Posted September 25, 2013 Share Posted September 25, 2013 Yaris diff speed sensor but then you loose dash speedo Quote Link to post Share on other sites
morgey Posted September 25, 2013 Share Posted September 25, 2013 I've seen a bodged together mechanical speed sensor which was made up from a electric sensor so he could use both mechanical an the ellecy. Did look shadey as fuck though lol Quote Link to post Share on other sites
glanzagee Posted September 25, 2013 Share Posted September 25, 2013 i have a few thoughts about this by taking off the speedo cable and putting a yaris 3 pin speed sensor in the gearbox just need to change the plastic gear and fit on to the sensor which reads off the final drive gear also could you not tap in to the wires to read off the sensors aswell ?

mech5107 Posted September 25, 2013 Share Posted September 25, 2013 The stock dash is converting the mechanical signal to square wave signal for the ecu. Check your ecu pinout and find this cable. This will give you the front wheel speed. For the rear, just tap in the abs sensor signal. Quote Link to post Share on other sites
D3N0 Posted September 25, 2013 Author Share Posted September 25, 2013 Yaris diff speed sensor but then you loose dash speedoDefinitely an option for driven wheel speed. Only thing... I'll probably have to replace the dash with an electronic one... maybe a SARD stack display. But even on dash replacements we don't really have an option like other European cars.

But that wouldn't work with our dash clocks though.Im using the JT-Innovation Toucan display unit, but where it sits in the car I I wouldn't want to use it to guage my vehicle speed.I see what your saying about tapping into the existing wires, but which ever way you look at it..... its still botch. Preferably you'd want to leave that alone really.... safety device etc. Quote Link to post Share on other sites

glanzagee Posted September 25, 2013 Share Posted September 25, 2013 If your splicing in to them best do it under the drivers side dash where they all meet to go into the abs Ecu ;) Quote Link to post Share on other sites

RobSR Posted October 6, 2013 Share Posted October 6, 2013 ^ wouldnt you want speed for each front wheel tho not just both combined? as they wont be both going at the same speeds all the time.and regarding what they look like, from another thread a few days ago - http://www.ukstarletowners.com/topic/71060-anyone-know-what-ecu-this-is/ Quote Link to post Share on other sites
yaristurbo Posted January 14, 2014 Share Posted January 14, 2014 d3no did you get any further with this mate Quote Link to post Share on other sites
