AbbeyMS Posted February 16, 2016 Report Share Posted February 16, 2016 I am trying to get a Traction control set up on a Nissan Skyline R33GTST, this car has ABS luckily.We picked up the ABS sensor signals , being a GTST it has only 1 rear wheel speed sensor , we knew this would provide a signal with too much frequency, we saw this when tuning on the Dynapack the signal was dropping out due to very high frequency rate as we thought. We have a fix to cure this by using a Race technology VRS converter https://www.race-technology.com/gb/racing/products/sensors/miscellaneous-sensors/miscellaneous-sensors_vrs-signal-conditioner We picked up a front ABS reluctor signal again again we think the frequency maybe to high , what we noticed the front signal doesn't "wake up" until around 40kph.CAL File is attached 16_02_2016 dynofinal TRACTION turned off.pclrAny feedback will be greatly appreciated. Thanks 16_02_2016 dynofinal TRACTION turned off.pclr Quote Link to comment Share on other sites More sharing options...
Simon Posted February 16, 2016 Report Share Posted February 16, 2016 The signal will need to be up over 1.5V for the Di to detect it.I would suspect it is a reluctor sensor and it could well be below this level up to that speed.If possible closing up the gap could help.Frequency will be an issue assuming its a 40ish tooth ABS ring.

AbbeyMS Posted February 23, 2016 Author Report Share Posted February 23, 2016 Simon, is there a max voltage that the Dig inputs can take? as moving the sensor closer to the reluctor will increase the voltage and running at speed will increase the voltage. thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted February 23, 2016 Report Share Posted February 23, 2016 They will be all good up to 40+volts off a reluctor input. Quote Link to comment Share on other sites More sharing options...
