The Great Intake Face Off - RESULTS!

[billapex]

Yes, K&N does sell a cleaning kit that comes with the cleaning solultion and filter oil. Your local auto parts store should carry it, probably at about $10.

If we need to re-program to realize any gains from a cai will the dealer do this for you if you buy the mopar intake and have them install it?

Nope!!

[MattRobertson]

Nope!!

And would they even know what they're supposed to do in the first place? :D

and even if they wanted too, could they?

[MattRobertson]

and even if they wanted too, could they?

Executive summary: No they could not since even the dealer can't even wing it on a tire size, let alone all of the funky parameters associated with what we're talking about here.

The long version: To take this whimsical banter a bit more seriously, probably not. As I understand it the StarScan system is more meant as a tool to put in a series of predefined choices into play ... i.e. you have one of 6 tire sizes to choose from. However if someone builds a programmer that can feed the computer an entirely different set of tire parameters than one of the six predefined StarScan sizes, there's nothing preventing the computer from accepting that data.

But nobody has that in play yet, so boo hoo to us all. I am guessing GIFOPE will be an exercise in proving that the computer rules no matter what we do but it will be very interesting to test the yea or nay of said guess. If I can make it up CV and I have discussed putting my car on the dyno as a loose-cannon test as I have had a Typhoon on since January and Zoomers since May. If anyone wants to question burn-in duration (which has already been done for the interval that will be used in Rnd 2) that run may prove of interest as another benchmark.

Chapter 3

In an OBD II equipped vehicle

That may be true for a vehicl that uses an ODB II computer, but I thought the LX vehicles used some new thing. CAN BUS or something like that, not ODB II.

Anyone else have some info on the Engine Computer used in the LX vehicles?

LX cars do have the CAN programming but its an update of the OBD-II. The electronics on my Charger R/T, are VERY similar to the setup on my Stratus. The MAP sensor on the UIM, evap canister and hoses follow the same path, and even the EGR has a similar setup. So its following the same protocols for sure. Dont know what the differences in CAN are though. It could be the elimination of the fed spec vehicle. There are some things in the bay that I dont like and will definitely be changing.

That is what I have been saying for a couple of weeks here. If you can't unlock that computer nothing will happen.

Totally untrue. If that were the case then why does a vehicles performance decrease at a higher elevation and increase peformance in a lower elevation in respect. These programming has the ability to go both ways. A balanced setup is the key where one sensor is not overloaded by another.

ChargerOsix,

Its obvious you're very experienced and have done some serious experimentation. I'm curious, what explicitly do you expect the GIFOPE tests to show?

Specifically, if you had to guess, how much hp and torque can we expect with:

Volant after burnin:
Volant after computer reset:
Aircharger after computer reset:
Stock after computer reset:
Airaid after reset:

I'm guessing the Volant after burnin has the best chance of yielding results, but how much I've got no idea.

Your thoughts?

[RandomAccess]

What makes you say volant would yeild best results ? Data still shows Aircharger with the highest HP Results

[CoolVanilla]

As you can read here and on many other threads, folks point to the lack of time for the computer to adjust as one of the main reasons our results were so uniform in yield. That first test of the day will prove or discount that assertion out of hand. If there is anything to the computer adjusting over time, that first test will show it.

PS: The first run of the initial tests did this same thing, but that fact gets overlooks quite often.

PPS: The above statement assumes there is no form of permanent memory storing the "learned" parameters across "computer discharges". Its entirely possible there is permanent memory in there, but there is simply no way for us mere mortals to adjust for that factor.

Bob is actually out of town on 7/29. We're probably going to need to reschedule for 8/12. I'll get confirmation of that hopefully tomorrow and let everyone know.

What If I can come up during the test? I will have both the Mopar intake and Mopar Cat back by then. As long as its past the "Burn in", My HP should be greater then stock. Would should see that in the Dyno. If we see no change, we'll know for sure that burn in isn't a factor right? In fact, that all mods (Intake and Exhaust) are just for giggles and noise.

What do you think?

Go and get the dyno test. It would be another data point to muse over.

(I have the same setup, so I am really curious)

Peter, I'd love it if you can make it (please remember the actual day is still up in the air as of this moment). I agree with the concept, but wonder... how do we know what your Magnum put out, stock? Did you dyno it before the mods? I don't think we can safely compare my stock numbers to your mod'd numbers. It really hard to draw die hard conclusions from data gathered by two different cars.

That concern aside, come on over! At the very least you'll get to meet some of us buffoons, see what your Maggie puts out and how fast she runs at the track.

[PBatt]

I agree with you on the stock vs modfied, but the number between cars should be same yes? 340 HP for each at the motor, and ? at the rear wheels (sorry, don't know what the RW HP was). But, If mine Dynos at 20-30 HP more then the test cars, doesn't that show a net gain in the mods?

BTW, where will I be driving too?
