Controlling brake line lock with launch control
Posted: Sun Dec 08, 2019 8:05 am
Hi guys,
Has anyone used an electric brake line lock together with the launch control system?
In our new car (S100) we'll be implementing the launch control, mostly for accurate startline rpm. The way I've previously wired this up was;
-DTA pin - steering wheel LC pushbutton - clutch pressure switch - ground.
So ECU holds startline rpm while button is pressed, driver aggresively releases clutch pedal, car goes vroom.
Now for our new car we'd also like to incorporate an electric brake line lock valve (anti-roll valve) that temporarily holds brake pressure after having applied the brake pedal. We'd like to prevent the car from rolling and being able to preload the drivetrain (similar to drag racing, but this car will be doing offroad heats with sensor-monitored standing starts).
The low-tech way I've thought of was simply using two clutch switches and a 4-pin pushbutton to simply have a separate wiring loop control the relay for the line lock, but this feels counter-intuitive.
Any way to do this using the DTA?
thank you for any input!
