when you disable torque model, set correct the throttle linearization 16x1 map, elsewhere you will idle at 2300 rpm  |

hmm yes, setting the launch rpm is nice and all but i really think we need to find a way for the throttle to stay open, or at least keep bouncing the limiter rather than the PI controller for the throttle taking over and just holding the rpm.
could get a decent 2step at that point. i have been playing with this a bit, not letting fuel cut ever come on, but you need to keep the limiter bouncing with throttle being open for it to build some real boost.
anyone have thoughts on where to go at this point? i know why it wont let me, but how to work around this and not really affect a lot of other protection in the ecu.

My car seems to bounce the limiter just fine... I don't think the throttle is closing. This is with the limiter set to 4500. I haven't stood on it long enough to see how much boost it will build. To my knowledge you'll also need the ECU to intentionally randomly misfire on the exhaust stroke to build full boost. Here is my Mbox with the parameters posted earlier at 4500: http://www.youtube.com/watch?v=lhszz7OTtAEPardon the color sanding mess. I haven't tried launching it yet as I haven't finished tuning it due to wideband issues. However I will say that given the fact I already twisted up a propshaft launching with no boost... I'm curious to know if it will help or hurt. The car was hooking up pretty good launching about 4k with no boost. Got some wheelspin this day because it was about 105 out. http://www.youtube.com/watch?v=tmE8VjffJUYIf you listen close you can hear how loud my clutch is, lol. |

Codeword Drehzahlbegrenzung it looks like is what it is. codeword for speed limit according to google translate.
Can someone explain the maps named "codeword...", whats the funktion of these values? BR |

Codeword usually refers to a single value or a value made up of multiple bit flags.

Can you give me an example, i do not really understand it. for ex. in the a4 map attached in this thread, whats the difference between Codeword=0 and codeword=1 ? Many thanks |

Codeword Drehzahlbegrenzung could be two things. It could enable or disable the speed limit. I would assume 1 is enable, and 0 is disable. Or it could be the actual speed limit. But I am pretty sure it is just used to enable and disable.

Has anybody figured out yet how the Maestro Suite makes 2 step work with a clutch signal yet? I find that far more interesting than something that disables itself after 10 minutes.
Thanks.

i tested this to my leon 20vt with big turbo gt35,and the results are quite good for the launch function but i have a problem with the raised rev limit,it's not stable.
i put the limit to 32000 but the limit is not always the same..
sometimes is 7600 sometimes 7800 and sometimes 8000,why is this happening?
try to raise throttle limit but it even worst.
any idea?

Sorry for the long wait for a reply. It sounds like DNMAXH is set too high, keep it under 100 RPM. According to the Funktionsrahmen, the absolute maximum RPM is NMAXOG + DNMAXH. |

I am so sorry to be offtopic, but can we use this stock 2stage rev limiter so that we have to different limiters for different coolant temps? For example because my wife takes the car often (and as it is well known women have no respect for cars) can i set a limiter of 3500rpm until the engine reaches it's normal working temp and after the limiter to be raised to 7000rpm as normal? Thank you.

Good question, and yes the raised rev limit is flexible. Set NMAX to 3500. NMAXOG to 7000. TMOTNMX (Coolant temp for activating raised limiter) to somewhere around 80 (degrees C) also set the other maps for launch control. Let us know how it works |

Great news. It is working plus that temp tweek. You cannot exceed the lower limit if the coolant temperature is lower than TMOTNMX. Very useful when your wife uses the car for shopping !! Thank you Nosbeui |

Thank you Nosbeui My wife floored my car only once, since then she is driving easy. I think something about "omg I feel nauseous" has to do with it  |
