I got in touch with a highly recommended custom tuner today though.
what Tuner are you working with?
I can tell you from my experiences that I have had ALL of those codes on my 3.6L RIPP setup ...and pretty mush most all of the guys here that I have spoken with that have RIPP setups have had some or all of those codes as well...their tune gets you in the ballpark but you really need a custom tune to work out all the issues...there are quite a few variables that can cause these codes...you'll prob start getting PO 300-306 codes as well...those are misfires...they come hand in hand with the knock codes
rich/lean can be associated to boost leaks...leaky oring on the injectors...and a multitude of other things...tuning etc...
the BIG things I found on mine that you really need to keep an eye out for are :
Gap of the plugs (mine runs at .032")
Orings on the injectors...very easy to install with a crushed or damage the Oring
Boost leak...can come from anywhere in the system
Oil blowby can DEF cause the knocking ...really need a catch can and try to eliminate the oil breather air from the intake air...meaning running 2 catch cans or a catch can with a breather after the PCV -totally eliminating the breather line from passing oil vapor back into the system.
have you checked your air filter? If there is ANY oil in it or on it then you are getting blowby....and you need to fix that
Fuel is a big one...really need to run nothing less than 93 octane
I also would HIGHLY recommend having an AF gauge installed in your jeep to monitor the AF at all times....
I've worked with a couple tuners...but would recommend working with a local tuner that can tune on the dyno...that's really the only way it's ever going to be right...bolting the SC kit on is only half the battle...it still requires a LOT of tuning and detail work to make it safe/right
Sleeper GC ...the RIPP tune stinks with the shifting ...I had the exact same problems with my 3.6L stage 1 kit ...I had to lift between shifts to get it to perform properly....when I mashed the pedal I would get a 0-60 time of ~5.4-5.6 Sec ...by lifting between shifts I improved that 0-60 time to ~4.6-4.8 Sec consistently
My new setup is being tuned with HP tuning ...the diablo tuning is pretty limited in the parameters you can adjust according to my HP tuner...my tuner told me that there is no way to really adjust the shift points with the diablo or HP as well...with the HP tuning he had to adjust the fuel/spark/timing at the RPM where the vehicle shifts and now it BANGS shifts incredibly hard now...NO more lag or having to lift between shifts ...
I would recommend having a custom tune done to work on the shifting....it takes a long time so expect to pay a fair amount to get it right...my jeep has been at the tuner for the past few weeks and has been on the dyno for over 20 Hours...and they burned over 50 Gallons of fuel on the dyno so far
...it's getting close...but not quite done yet...
