    Who is familar with tuning 2011 Camaro DI V6 E69?

    Just looking for basic tuning steps not familar with these Bosch ecus like I am the LS stuff I normally deal with. Change MAF table so part throttlefuel trims are more in line

    Knocks sensros are CONSTANTLY going off

    timing anywhere from 7-22 degrees at WOT?

    pm me .. i have a 2010 Camaro Supercharged Running 16# of boost .. KR is usually cause by running these motors too rich.. or too low of timing

    on average your Trims are -15-20%

    these motors like to run lean.. from personal experience when my trims were +-1% i had a good amount of KR in the logs when i leaned it out alot of the KR went away... the LNF uses the same ECU CSSOB and Term have a bunch of great write ups

    uhh if you are at zero trims and lean it out o2s will put it right back and trims will be positive??? that makes no sense

    your getting KR from too much fuel so if you have a wide band and look at the AFR error your gonna see that when you tip in or at low loads the afr will almost always be negative with trims close to zero. almost as if the ecu is using the o2s too late if that makes sense. by making the trims positive your afr error will be slightly in the positive and the o2s wont be late .. i hear what your saying and battled this for a long time and finally figured it out.. just a bit of advice from what i did thats all

    So what did you do to fix this - reduce the MAF table values? Did you reduce by a particular percentage (for the whole table)?

    The knock sensors are too sensitive, I had to set them at 3.5 on the same car that had LT Headers & HF cats.

    3.5 meaning that you multiplied them by 3.5? And are we talking about the Engine->Spark->Knock Sensors->Knock Sensor Level Multiplier tables for each cylinder?

    Just curious.... My application is very different (2012 Impala with 3.6L LFX, 6T70 trans), so not so sure this would apply to my car anyway... I have raised the multipliers a little for 0-3000rpm to help reduce false knock in the lower RPMs, but I'm hesitant to increase them too much....

    Knock sensor gain, just raised cyl 1-6 to 3.5 (the max).

    Ok, thank you. I don't even have a knock sensor gain table in my setup (E39 / T43), so I guess it's setup differently than my application. For some reason, I was thinking that we were talking about the LFX Camaro's, but I think that we're actually talking about the LLT Camaros here, so that is probably the difference. :-)

    you are correct the LLT has the KR sensitivity tables.. you may also want to look at your cam timing this can create low load KR
