First impression after day 1: Noticed it did tach up more quickly in N but can't really say I noticed a significant difference under load (acceleration). That could be in part to 3.73s and 37s, not much acceleration there.

It does seem to cruise a bit more easily on the freeway and pull a bit better on inclines.

I am still waiting on the 4-3" reducer. I ended up using a 3"-2 1/2" and think that is causing some constriction but probably not enough to be noticable.

BTW, this is with a Hypertech tuner on the high octane setting and K&N filter, no other mods. NO CAI, CAT BACK EXHAUST, nothing.

No problems with codes, lights, nada.

Will post up again after running thru the first tank of gas.

 

Sounds good so far and I was wondering how the tip in was under load. Any hesitation or bogging (outside of 3.73s and 37s) under load? Then the other side of the coin at WOT?

Those are probably my biggest two fears as I have headers and the propensity to run lean is greater than most. Then throw a programmer on top which further leans things out a bit and I can revert back to the days of running higher octane than the supported tune and perhaps even colder plugs again.

That said, I'm glad it's working for you and hope it continues to do so after the PCM relearn rolls through it's paces.

 

Looks great!! Thought about doing the same thing on my 07 till i found an Airaid CAI on Craigslist for 100$

Brainstorm--I think the only thing that would make this a smidge better (of course assuming theres room) is some type of triangle shape plate, going from the radiator corners to the bottom of the intake(filter on top). Hypothosis is that it would help to keep the radiator/engine heat down and act as a bit of a splash gard. Can never be too careful with water.

May help, may not. Popped in my head so i thought i'd share.

 

Tip in under load? Not sure what you mean here?

No bogging noted, throttle response seemed to be up a hair. WOT didn't seem to notice any significant difference.

Figuring that also by not running a CAI or free flowing exhaust, these things might actually help me to keep from running too lean.

Mebee I'm of here also, but isn't it only the guys with the 2010 JKs that are having problems? I kinda ferget after reading so many different threads on the different boards.

Feel free to set me straight on the years of JKs having problems with this mod.

 

Meaning when you first pus the accelerator, not jabbing or stomping it, but gently tipping in and actually beginning to roll, hence under load.

There are definitely some people with the Flashpaq that aren't fairing so well with this upgrade. The envelope must be pushed a little further and people are getting CELs. Either or seems to work fine for these people, but both is a non-mover. That coincides with what I was told by an engineer at Superchips when this whole topic first reared it's head a year and a half ago.

Haven't seen enough to pin anything on a year from what I have read, but not exactly what I was looking for.

For the time being it's out of bounds for me as I don't think I'll be giving up my Flashpaq for a throttle body. Also, there is a thread on the SC forum covering this topic and their tech support puts it out of bounds for Flashpaq users.

There is one guy out of a hundred who has had a problem and he uninstalled the Superchips and still has a problem. I think it is something else on his Jeep. One person, that's it.

 

That could well be. It's a small community and things get echoed through the various forums.

Here's what I have from Superchips lead engineer on the subject.

It is a LOT more than a simple throttle re-learn. That would have to be calibrated for.

Also, Anyone using it will risk hitting a limp home mode where the application shuts down. On a tuned application it will run dangerously lean in open loop (WOT/ Hard throttle).

Just remind them it is a MAP system still. Airflow is calculated, change mechanicals and the airflow calculations go off.

Here's what Superchips Tech Support has to say on the subject,

No, that would not be a good upgrade for your setup. It will not work with the tuning either.

Your motor is still regulated by the volume of the intake manifold and cylinder design.

You are getting toooooo much air. Its going to eventually throw a CEL.

Even worse. ETC (electronic throttle control)

Is not what I would want to be messing with.

That said, I still wouldn't dismiss this upgrade in it's entirety, just that it's not currently for me and at minimum for the Superchips user I would start out with 93 Octane running the 87 tune. Run a couple tanks, keep an eye on the knock sensors and if you don't have an issue move up a tune.

I don't want to rain on anyones parade. I just see enough red flags where this should be approached with great caution. If I were starting over again, with the knowledge this was out there, I probably buy a Diablo Predator, Ripp long tube headers, the replacement throttle body and have a custom tune built. That's just not where I currently sit and I am probably sitting on top of the list for potential lean issues as I often run an intake, have headers, exhaust and a Flashpaq.

 

Hmm....


2010 JK....


Superchips....


Viper TB....


Has anyone seen problems from other years of JKs? This problem may just be specific to 2010 JKs running the SC tuner.

I haven't seen anyone have problems with the Hypertech tuner. Mebee a problem with their tuner.

Haven't seen problems from other year JKs.

Set me straight if you have.

 

What are the oxygen sensor for?

 

They have 2 purposes. The first oxygen sensor monitors engine out oxygen levels to make sure that the fuel map is appropriate for conditions. If it senses an oxygen level that is too high or too low it will switch fuel maps for the engine until it is within operating parameters (or will trip the check engine light and limp mode if none of the fuel maps fit keep it within proper parameters). Secondly the ECM uses the readings from the pre and post catalytic converter O2 sensors to make sure that the catalytic converters are functioning properly.
