Hi all,

was wondering if this would be possible to achieve on my speedway car (VL Commodore V6), I could easily fit wheel speed sensors front and rear, just need ideas on how to go about using that info to create torque management....

Thought appreciated,

handbrake?

Not sure what you mean, car isn't fitted with one...

I'm guessing handbrake was a joke? I know I wouldn't want my wife in a speedway car...LMAO

I could only assume you'd have to use another module to register differences between wheel speed sensors & then have a signal out to PCM to retard timing or something along those lines if it is at all possible?

Thats exactly what I had in mind, but not sure where to start

Yeah it's sounds pretty cool if it can be done & will be watching with interest!

Was thinking similar too. An external module could output a signal to the 424 and would engage power or economy mode which would have a lower timing table. As for the module to monitor the wheel speed I'm no help with anything off hand there.

there already is a sort of traction control. RDSC. Thats enabled by default and sudden changes in rpm and load conditions it retards the timing.

Its one of these things I discovered inhibited performance on the VR when I was tuning it and stopped it from breaking traction when dumping the clutch.

There is lots of settings related to this so it can be fine tuned.

That would be the way I would go. If set up like a knock sensor, i.e. the wheel sensor detects wheel spin and relays the message back to the ECU, it would reduce timing until traction is achieved.

Traction control, isn't that what we use our Right Foot for?
