Are 5th gen V6 camaros prone to false Knock?

[WS6HUMMER]

I've been using HPT for going on 11 years and this is the first V6 I've actually attempted to tune. The car I'm working on has a LOT of KR even at easy driving situations, is this common? I'm working on a 2011 Camaro btw. KR LOG.hpl

from personal experience YES, my 2010 was over advanced from the factory took a few degrees away and much better. also look at your fueling if thats off too much it will create knock in the lower rpm/load areas 1500-3000 rpm that is where most of mine was. these bosch ECU are not easy to tackle..but tune very similar to the LNF and there is great info on here to learn from..

just looked at the log send me a pm some thing i need to point out

Thanks for the info, to be totally honest I have questions about the timing. Under main spark advance would I retard all 4 tables or just the max? Looks like optimum spark is for just torque calculations. I'm lost when it comes to a v6 & multiple cams lol.

depends on the miles and the valve coking. coking kills the gdi engines. some take more timing, some take less. i have seen variations of all of them in the ones i have done.

Didn't know about the coking issue but it makes sense. He's running a catch can but I will recommend having some top end cleaner ran through it, thanks for the info.

the best way to take care of the issue is to walnut shell blast the ports. i see a lot of 3.6's cars falling to the wayside due to this issue.

Thanks I'm sure that's the only real way to get it completely clean but I'm sure I won't be able to talk him into doing it right. I'm sure that top end cleaner can only do so much.
