U know Cobb? That World renowned tuner company that says the BMW DME is overly Ambitious at pulling timing? And that random 3-6 degree timing drops is not knock? Ya I'll be switching to them unless Terry or Shiv can blow my mind with 100% pure water injection test results.

Just because shiv/cobb/terry or whoever say something, does not mean it is fact. Hell the 3 of them dont even agree on the topic at hand. |

If you look at how everything unfolded, facts were simply posted with questions at best. The community is quite sensitive when it comes to anyone talking about their respective tune. Even if what it said is true. Basic tuning theory applies on all cars. |

Well you are right in the fact that it is the only tune that doesn't modify the maximum ignition advance values. But they all control ignition timing in the same way. Please prove me wrong with actual facts because I know you are just going to say reread the thread full of useless assumptions based on marketing bs.

What's that, a stock ECU doing exactly what it is supposed to do when it encounters more combustion noise than it likes? OH NO! Quick, somebody put a piggyback or suboptimal tune on the car that pulls enough timing that the ECU doesn't have to do the job it was specifically designed to do!!
The whole reason ECUs exist IS to ride the "knock threshold." I say "knock threshold" with a grain of salt, because if you think the ECU is pulling timing in relation to actual destructive detonation, you don't have the foggiest idea of how conservative the stock programming is. BTW, I don't have a dog in this fight, I own a car that's fast and NA There's a LOT of BS on this board lately about reflashes. Fair number of folks on here remind me of nurses I deal with that get on WebMD....fair amount of knowledge but just enough to be dangerous and wrong almost half the time

You just haven't reached conditions where it would need to yet. Wait until it gets to 105 degree ambient temps and you put the A/C on, just like the original post...

wait, I'm still stumped. I understand what you are saying now, but it doesn't jive with what I'm seeing. Shouldn't I be having limp modes with all of this knocking? Shouldn't I have some knock codes, or something? anything?

Yea and in those conditions, if its not tuned for it, it will rely on the stock sensor. That the point. Try rely on the sensor in shit conditions, not all the time.

If you superknocked, you WOULD throw a Glow Ignition code. They're ugly little buggers.

So just a quick question to end the night. What is the hottest ambient temp you have logged the Cobb at so far?

yea, if you do, then the last measure of safty failed and you damaged your engine. You want to rely on your last measure 100 percent of the time, go ahead.
