i've just arrived from the dyno, this JK owner has the same problem; reflashed ECU by B&G plus the Unichip, the tuner has to almost turn down completely the injectors so it can idle adecuately, and in the medium to high range (3500 RPM up) the air fuel mixture goes dangerously lean (13.0 - 14.0:1). What we're gonna do is to buy a new stock ECU and check if we're still short on fuel and then see what alternatives we have, we prefer to install bigger injectors but i haven't be able to locate any info on that, seems that's the reason Ripp utilices two additional injector, which i believe isn't the best alternative.
If anybody has info about bigger fuel injectors please let me know

auxillary injectors with a controller like the megasquirt2 and a wideband 02 are very much the best answer ....
option A) ... mess with larger injectors and messing with a OEM ECU that was not meant for you to reprogram making it difficult at best.
option B) ... mess rising rate fuel pressure regulators and hope you can hit that perfect idle fuel pressure and boost referenced fuel pressure curve you need for your new bigger injectors to work well.
or option C) ... tap the fuel pressure test port with a line going to a auxillary injector that is easily controlled by a MS2 with just a few wires tapped and will auto adjust the air fuel ratio under boost in reference to a air fuel ratio map you can control based on wideband o2 readings.
anyway back to the detonation issue ... get a wideband o2 sensor on there asap, 250 for a aem, thats cheap and accurate ... check whats going on during detonation, is it leaning out or not ... lean situation = tuning is crap ... but if yo u got a nice AFR you know you got other variables such as the timing, intake temps, or need to run colder plugs ... maybe combo of all of those.
good luck with dealing with those companies ..

Ok, gotcha. They just have alot more people on here running the Ripp's, hence the feedback on the Hesco on here is limited. Although they do have alot of guys on here with knowledge of SC's in general, RIPP questions usually get answered pretty quickly. Hope you can get your issues resolved.

Fellow Jeepers... i am located in Kuwait and i have installed S/C kit from Hesco for my JK end of June along with a programmed PCM that was supplied to Hesco by P&G performance. (i paid extra for a new programmed PCM to avoid sending my stock PCM back and forth to USA to program it)
after the install I faced problems with detonation/ pre ignition with that PCM and did every thing possible to get rid of it but could not. (highest octane fuel available+octane booster/ colder spark plugs/ richened AFR ). The only remaining solution was to send the PCM back to USA for programing.
Ideally i should be sending the PCM back to HESCO but To expedite things... i dealt with P&G performance directly which was a big mistake...
We have agreed that i send them my untuned Stock PCM to modify my tune. for me to run it during hot weather in Kuwait, and keep the already tuned PCM to use it in winter.
I sent the PCM to them and it was delivered on September 08th, i spoke to them that day to make sure they received my Email with the notes of my observations of the engine behavior.. to enable them to modify the PCM accordingly. they confirmed that it should take 2 days.
TILL today...And after more than 3 weeks and many follow ups and calls.... i am not able to reach any person in that company...no one even the Operater... No one.
I went back to Hesco and explained the situation in Detail over the phone. and we agreed that i will send Hesco an email regarding the same and they will take it up with P&G.
I tried sending the email many times but it was never delivered due to mail server problems at Hesco's end. And now i am not able to reach any one in Hesco either!!!
I am really frustated and have not driven my Jeep since i did that F&%#ing upgrade.
Considering that i am on the other part of the world....What can i do???

I have tried driving it with the stock PCM beforei ship it, the knock went away
but it was running way too lean for forced induction. around 15AFR.
the weather here is just starting to get nice .... i don't want to miss the off roading season

i have innovate LC-1 Wide band installed along with a G3 boost gauge and an aeroforce interceptor. i used those to monitor and record the engine behavior/ AFR/IAT/Injector duty cycle/timming. The AFR was around 14.6 idle/ cruise and around 11.6 going WOT, and i have installed 1 level colder spark plugs.. intake temps range from 110-135F.
i have tried the highest octane available with octane booster and i have isolated the intake...still no good results. the only thing left was the timing.

this way you can Obtain a good AFR through the RPM range.

Update
Update... i was able to reach HESCO and they are also not able to reach B&G, but they assured to me that B&G are still in business and they have just shipped a PCM to HESCO. He will try to get in touch with B&G again.
No result but at least i reached some one.
