    So Vincent made a great post explaining Knock Count and Knock Control and the base 1.5T ecu just not playing ball at higher rpm + boost levels. So I was wondering if there was a way to combat that rise? I'm already running E40 blend and tuned by DRob but regardless hard driving will always start raising my knock control. I'm pretty much ready to part out my FK7 which I love and trade it in for an Si. I'd hate to do that but it really kills the fun when all of a sudden i'm just losing power gradually and the harder I push the more power I lose. Is there a way to modify the ecu parameters so KC is less sensitive?

    I don't see what the problem is.

    K. Control is there to protect your engine. High IAT's and running high boost for an extended period raises it, sure, but with sedate driving it comes down in a few minutes

    Upgrade the intercooler to lower IAT. You could also consider meth injection.

    Or avoid repeat high boost at high rpm situations.

    I imagine he left it there for protection. You could discuss it with him. A large number of these ECUs already have the sensitivity tables available.

    Drob said base 1.5t ECUs force the rise of knock control past 5xxx RPM no matter how you try to avoid it.

    I've had to change the way I drive to make sure KC keeps down. I've been shifting sooner which totally defeats the purpose of me having the VitViper turbo that lets me hold power until redline lol. And I try not to WOT under 3k rpm because of fear of destroying my rod. The ECU KC is the main reason i'm contemplating parting my car out and trading it in for an Si or Type R, even tho I love my build.

    I know there’s not too many good tuners out there right now for the civic X. But in my experience, DROB does not even know how to do simple math...as seen in some threads about the upgraded turbo. Yeah he might make your car go faster and not have you blow your engine right away. But I would NEVER pay for a tune from him :dunno:

    So... why are you the very first person i've ever seen make this sort of comment towards him, when everyone else who has his tune has 0 complaints?

    Interesting. Seems biased to be honest, not sure why you would say that here.

    Obviously there’s going to be a good and a bad to every single thing out there. I’ve just read some threads about people having issues with their tunes. And there was one thread I responded to about a dyno chart with an inflated tcf value of 1.25 Drob had posted the converted HP To a Tcf value of 1. He had not converted correctly. I do understand there are people out there that are good with things and some that not so good. IMO I would not want a tune from someone who isn’t proficient in ratios, as they are involved with calculating parameters.
    I was reading this thread and wondering why someone else isn’t having the best luck with a tune. So I started a conversation! I’m sorry if it came off in a wrong tone, I’m not trying to bash or change opinions

    I'm sorry you feel this way, @ryanfk7 . The fact remains that I have tuned more of these cars than anyone in the world at this point (there are literally thousands of CivicX/AccordX models using my calibrations, by no stretch of figure).

    @imcrspy , as KTuner mentioned, I do have access to knock sensitivity tables, but is the juice worth the squeeze? You have a stock FK7 engine (the least durable of all L15's, it seems), operating at a much-elevated power level. The factory knock sensitivity isn't a bad thing when it comes to keeping the engine alive.

    What the hell? D-Rob is all about making power but also bring mindful of where and when to make the power to minimize reliability issues.

    Have you looked into the adding of any aftermarket parts/tunes that could potentially add background noise, throwing off the knock threshold map, and in turn falsely adding knock control?
