Harrys Posted February 24, 2015 Report Share Posted February 24, 2015 Hi, I have an S13 with RB26 and drag box without speed sensor.Can I get speed signal from ABS sensor?As I know stock ABS sensors give analog signal (VR) not digital (hall).Can LINK Ecu read this analog signal from stock ABS sensor? Â Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted February 24, 2015 Report Share Posted February 24, 2015 We can take the signal no problem. The main issue is often the ABS wheel will reach to high a frequency at high speed due to the high tooth count. If you are able to reduce the tooth count it will be no problem.

Harrys Posted February 24, 2015 Author Report Share Posted February 24, 2015 I don't mind so much for high speed measurement.. I need only to use it for boost control. Less than 50km/h to have low boost and then high boost.So you think that I will be ok? In which input can I connect it?Expansion connector? Digital or Analog input? Or just at ecu loom at stock tacho wire (Aux 4)? Quote Link to comment Share on other sites More sharing options...
Simon Posted February 25, 2015 Report Share Posted February 25, 2015 It will need to come into a free Digital input. There will be one that was for the gearbox input. Or through the XS loom would also be fine. The catch will be when the frequency gets too high the speed will drop back to 0 which would reduce the boost.

Harrys Posted March 3, 2015 Author Report Share Posted March 3, 2015 And it will send me in launch control mode! So that's danger!! So I will try to remove tooths and check it first on the dyno!  Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted March 9, 2015 Report Share Posted March 9, 2015 12 teeth would be a good starting point. Â Quote Link to comment Share on other sites More sharing options...
