    Try making everything except the timing maps like the ones listed in this thread. Then work your timing tables up towards what are posted while logging the car. If it likes more, give it more

    Yeah it is a really bad one. He likes to mess with the optimum engine torque table too which is a big no no because it is used to calculate internal torque output according to optimum spark and lambda=1.00. It is not a torque limiting table.

    Upgrades, lol.

    Just read through the first portion. Make sure you log all your changes, and look for knock. Thats the biggest thing to look for.

    If your not sure if something went wrong, its best to park it than to blow something up. Don't forget that.

    No it runs great, just running the histograms i still got a bit here and there in maybe 3-5 cells at weird loads. I was going somewhere so i did not change them. the most part it has no knock.

    Better than the stock tune on 93 octane it has 3-4* of KR all through the midrange. No knock is better though just pull a degree out in those areas.

    IDC of the LNF or any other GDI motor is kinda meaningless because the injection time and injection window is so much shorter than a port injection motor.

    Question, I turned the Dal up to 399 and can not get any more boost out of the car. It has azzp DP and a K&n Drop in filter. I want to hold 22psi.

    Even restricting the wastegate opening with external means the stock turbo runs out of gas at redline. 19 psi is about it at redline for me. When you increase the flow from the exhaust, it's harder to hold pressure but you are making more power if tuned properly.

    Might be possible with more tables available to us in the future, but raising the DAL's higher won't do it alone.

    Are you seeing a spike of ~22-23 then a slight roll off, then it picks back up a lil bit??

    If you are catless, try a .045 pill in line and reduce your DAL table like in the Pill Mod thread. Should have no problem breaking 22 then LOL!
