sama Posted March 28, 2020 Report Share Posted March 28, 2020 Hello guys, hope all are doing well with this massive virus that hurting all of us badly. I wanted to know if somebody has any experience what is needed to install the G4+ traction control system, not sure if it works with the stock ABS sensors or needs a new set to make it work. Thanks a lot! Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 28, 2020 Report Share Posted March 28, 2020 Is it a supra plug-in ecu or something else? You would typically already have rear wheel speed available from the gearbox sensor so you just need to add a front wheel. If you have a plug-in ECU then the ABS signal will be too high frequency so you will need to either build a frequency divider circuit to bring it down to an acceptable level or fit some other separate toothed wheel for front wheel speed.

sama Posted March 28, 2020 Author Report Share Posted March 28, 2020 Hi Adam, Sorry yes it's a plug-in G4+ so to use the front wheel speed sensors I connect to the OEM wheel sensors? Do you have details? Thanks! Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 29, 2020 Report Share Posted March 29, 2020 There is a conditioned square wave wheel speed signal available at the ABS ecu that I would tap into. Pin 7 is the front right and pin 20 is the front left. You will then have to build a small frequency divider circuit like this to connect to the ecu: Quote Link to comment Share on other sites More sharing options...

orlando bello Posted April 3, 2020 Report Share Posted April 3, 2020 Hello Adam where or what website is the divider available. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 3, 2020 Report Share Posted April 3, 2020 7 hours ago, orlando bello said: Hello Adam where or what website is the divider available. Almost any electronics store should have a 4024, or ebay etc. Over here our local jaycar stores (a bit like radioshack) sell them for like $1.50 each. Search for CD4024. Heres an example: https://www.mouser.com/ProductDetail/Texas-Instruments/CD4024BE?qs=sGAEpiMZZMtdY2G%2BSI3N4a%2FfUmOafsfmk1lx%2BAgrRBY%3D Quote Link to comment Share on other sites More sharing options...
Scott33 Posted April 3, 2020 Report Share Posted April 3, 2020 FYI you can use a 74HC393 which has two 4-bit counters in one package. Saves space if you need all 4 wheel speeds. In a TSSOP package, the board fits on the end of an AT04-12PA-BM* header, making for a compact addition to a wiring harness. Quote Link to comment Share on other sites More sharing options...
Stuart mcharg Posted September 17, 2021 Report Share Posted September 17, 2021 Hey @Adamw, sorry to bring up old content. We are currently trailing the same thing. Where did you find that wiring diagram and more to the point the raw signal(input from speed sensor) is that directly from the input to the abs ecu?

Adamw Posted September 17, 2021 Report Share Posted September 17, 2021 Yes the input to the 4024 chip would be one of the conditioned signals I highlighted in the pink box above that runs between the ABS and traction ecu's. Quote Link to comment Share on other sites More sharing options...

Thanks Adam, I think that's our issue, no traction control from factory. The link doesn't seem to be able to pick up the frequency. Quote Link to comment Share on other sites More sharing options...
