  • The parameters of the launch control with stock turbo kkk7000.

    Guys, what parameters to use for hard LC?
    Do these
    LC ignition Retard rpm - 3800
    LC ignition cut rpm - 4000
    LC fuel cut rpm - 4100
    LC ignition angle - 7.5

    Retards work, boost 1 bar, but the rpm does not freeze at 4000-4100 rpm. The engine continues to spin. What am I doing wrong?

    Is the rpm only higher or doesn't work the cut? ign cut should hold the engine speed down - maybe not exact on the rpm you setted caused by the acceleration of all parts?!

      Yes, the cut does not work. The engine continues to increase speed. Retard at 3800rpm is activated.

        what is this for AAN or 3B? if using my stuff from 3B patch the throttle has to be pressed down above 90% for the cut to activate. this is how i keep the spark cut from interfering with daily driving since 3B has no wheel speed input.

            they are whatever you want them to be. if you want it to make 5psi you adjust till you get that, if you want 10psi at launch you adjust till you get that. there is no set in stone configuration for it.

              I do not know why it does not work. Ign cut rpm - 4100 , ign Retard rpm 3800. Rpm do not freeze on 4100, and continue to increase.

                But does it cut the igntion or revs it up like without the mod?

                  Retard at 3800 rpm works, cut-out at 4100 rpm is not.

                    ignition angle is ATDC not BTDC. set it to like 50 degrees than try it.

                      Ign cut is only active when no knock is noticed. May you should check your engine/wiring/DTCs etc.

                      /edit:
                      Just took a look into the code, to be honest I don't see a "real" spark cut only a advance over the limits. Same for fuel cut. Don't found it..

                        Next time I will connect the emulator and try to make a video, how I change the parameters and how the work changes.

                          Tried to do it on another car, the situation is the same.

                            Try increasing LC fuel cut RPM more. For me, fuel cut LC doesn't work, same symptoms as you describe here - I didn't investigate it enough though why it wasn't working. Spark cut LC works OK.

                              thats not right. launch control spark cut happens before knock control is disabled in code. knock control is disabled only at high RPM for spark cut rev limiter and flat shift.
                              This is exactly how the whole routine works. i have commented everything that is important.
