PHYSICS ECU maps implementation

    Agreed, is there any effect on engine braking for example.

    Throttle maps shouldn't take any effect on engine brake.

    It only changes the responsiveness of the electronic throttles.

    So ECU/throttle maps have absolutely no effect on mixture and ignition curves, for more examples ?

    Not throttle mapping.
    Fuel maps would have influence.

    As would ECU maps, the OP.

    The ECU pretty much controls and monitors everything to do with the running of an engine.

    From monitoring sensors, to controlling throttle opening, (assuming fly by wire throttle control), fuel mixture, ignition timing etc.

    Dude, the original post was NOT just about throttle mapping.

    It included other parameters also.

    Your statement,... "Throttle maps shouldn't take any effect on engine brake."

    So you know for a fact that the closing of the throttle is NOT controlled by any of the ECU maps , and therefor how the engine braking is effected when dropping the throttle?

    Including cam shaft position, which could also have an effect on engine braking.

    Imsa is NOT the series in question.

    Please not that aggressive.
    Why have i putted "throttle" on bold letters?
    And these links inkl. "imsa" were just a sample, feel free to download every catalogue and every single tech sheet and read them all.

    You didn't respond to my last post.

    "Your statement,... "Throttle maps shouldn't take any effect on engine brake."

    You are the one making definitive statements, but not backing them up, I am simply asking questions.

    Until then.

    For me, it doesn´t make sense to discuss with you, as i don´t wanted to pick a fight and imo it seems, you mix up different Maps or for you its all the same.
    I wouldn´t use these two words as one is the other, so I wouldn´t with torque map and fuel map.
    My Statement was already, that the throttle map only has effect on the responsiveness of the pedal, linear or less aggressiv, for example. And I used the word "shouldn´t", not the words "for a fact".

    And this sentence:
    has nothig to do, with anything I wrote before or ever will.
    You´re twisting things up here.
    Way too agressive.

    Once again you continue to ignore the OP is about ECU maps, all aspects.

    You introduced singling out throttle mapping, I did not.

    One more time, are you saying that ECU mapping has no effect on how much engine braking, and in what manner it occurs when the throttle is closed ???

    I'm done here responding to you, we have already put a damper on a VERY informative post by Aristotelis, must piss him off royally.

    My apologies.
  12. sps_for_race

    sps_for_race Simracer

    No, Karsten Beoulve did, you replied with his quotation, which was singling out throttle mapping and no other ecu mappings at all. Please stop twisting my words.
    Again, way to aggressive.

    OK, I see your point of view, you assumed I was talking just about throttle mapping, when I was replying, maybe not very well,... to the OP in general, which includes all aspects of ECU mapping.

    I was also recalling, to myself, an earlier thread about how there appeared to be less engine braking in this series, than GT3 in AC1.

    Again, apologies.

    Is it possible that we could get a visual representation of the different throttle maps?
    Alternatively I suppose we'll just find it in telemetry later, but it would be nice not having to test 8+ maps for 10+ cars :D

    just one question:
    when the damage model will be implemented, will there be higher risk of an engine failure/overheating when someone uses qualy mix all around? at the moment we are able to do full races with the sharpest engine map as the fuel can last for 60-65 min, but in real life i don't think it's the case.

    GTR 2018 has ECU Map = 0. I presume this is the fastest?

    I settings preset its 0, but while driving it is 1, 1-4 available.. bug?
