Traction-control idea.

Post by doo0T!doo0T! »

I'm sure it's been thought of many times before but is there any chance of an upgrade in the future to incorporate traction control?

Most chassis types (even the EF) have an ABS braking optional extra with rear wheel speed sensors so could this signal be used as an input for the ecu to reference rear wheel speed against drive wheel speed to measure the amount of slip and retard the power though a choice of ignition or boost level to keep the amount of slip under a specified amount?
As i understand it it's a resonably high resolution signal from the wheel speed sensors so could likely work quite well.
Any chance of making this happen? Even if it required alteration to curcuitry like the boost control function does?

This is not possible as the ABS system is not integrated with teh ecu and there are no inputs to allow the ecu to see 4 wheel speeds.

I realise it's not already incorporated, it has it's own stand alone ecu for ABS, I mean run an input to the S300 of one of the rear wheel sensors.

I figured most people requiring traction control are going to have an LSD so under accelleration and traction loss, front wheel speed diference will be negligible.
So just use the oem speed sensor on the final drive for the front wheel input and just use one wheel speed sensor at the back.
The ecu already reads the speed sensor at the front so you'd only have to accomodate one extra sensor.
It should work ok with only one rear wheel being measured, only under braking would rear wheel speed differ greatly but lets face it, under braking your not going to require accellerative traction control.

If you could incorporate some sort of traction control into Hondata hardware thats a pretty good one-up on your competitors products.
