Launch control fault

Post by Denis_RSX »

Hi guys.
Acura RSX'05 and K-pro 4 generation, Honda traction control.
I want to activate launch control in car, turned in calibration clutch switch "always on" and 2700 rpm. Launch control did not work.

Then I connected the clutch switch to the E22 ECU following the example
http://forums.clubrsx.com/showthread.php?t=748200
I checked, when pressing the clutch, in the wire voltage of 12V.

Then I turned in calibration clutch switch "E22 brake switch (12v= on)" and 2700 rpm. Launch did not work.
What could be the problem?

Thanks!

Please post your calibration and a datalog made with that calibration that shows the problem.

Have you tried inverting the input?

I fixed the Launch control.

Burnout rev limit to "allways off" and Launch control became active.

I also followed the steps from that write up for wiring in the clutch switch to E22. Tapped into the clutch switch power wire and ran it to the ecu end of E22. However mine is always active according to the sensor list.

My clutch switch is working as I cannot start the car without depressing the clutch. But when logging with KManager, the brake switch sensor is either always on or always off (if invert input is toggled). Pressing the clutch never seems to change the input to the ecu.

Then there may be a problem with the clutch switch. Test the switch and see if it is working as it should.
