    I've always preferred more advance and less boost. In part because that is easier to achieve with the tuning hardware we use, but also is technically more efficient. e.g., better gas mileage, lower EGT, etc. It's also more responsive IMHO. But more boost and less advance can be more stable in higher effective compression / octane limited environments, like we see with 18psi+ on smaller turbos. So if octane is limited it's a good way to go for a given power goal.

George, I'm sorry if I offended you in any way. I don't understand the sudden hostility seriously.

    I'm actually glad I asked that question as I suspected you wouldn't have the full picture of what the DME is doing as you probably haven't had the chance to mull over and test with individual timing cylinder corrections on your car. With Cobb we can log timing corrections across the entire engine, not just a single cylinder. I've seen datalogs where the DME is correcting a LOT more than in 3deg increments. In fact at times I've seen 10.x deg in timing correction being pulled on certain cylinders in certain situations, all depending on HOW it calculates the required timing corrections on a per cylinder level. This is why I earlier said that I'd like to dig in a bit to see what it is that the DME is using in its timing correction calculations to reactively as well as proactively respond to knock.

    In addition to that, as someone else mentioned, there will be learned octane adaptations where the DME will automatically correct based on learned values over time, but that is a separate topic at this time...
    The actual timing correction is correlated to the advance the ECU is requesting post-shift. If you targeted 12 degrees in that load cell, you'd see a 13.5 degree correction. The issue is for those cylinders that flatline timing, it will flatline to -1.88 degrees. Being that the ECU will correct to -1.88 degrees after the shift like clockwork, I believe there's a table that isn't available yet that failsafes when the car is unhappy with something.

    The car's definitely detecting it as knock, that's for sure.

    I'm looking forward to what @dzenno and @jhershorin can come up with.

    Would hurt driveability and spool though.

    Give me a high compression ratio in a street car any day. As long as the octane and tune are solid the more CR the better!!!

    The conversation has gotten down right hilarious over on E90. I love that romanian douchebag.

    E90 is getting worse and worse especially in the n54 turbo section. There is not enough technical discussion and everyone has to be very pc when discussing anything with sponsors.

    Even if there are people that appear to attack a sponsor, a sponsor should be able to provide a response with facts. Then, those reading the thread would be able to decide if the explanation is sufficient or if the "attacker" has a point.

    I'm done. Just got permabanned for telling some members asking about Modbargains that they could be reached on bimmerboost. So much for helping the community.

    you mean the one that think he has a fast car and hates piggies but its looking to change to COBB since GIAC cant do $#@! about making more power or add support for upgraded turbos like my 1000 bucks i threw away with their tune?

    That place is an asylum. Unfortunately it will get worse since these cars (and eventually any high end cars) will become affordable for your local community riffraff.
