Just wondering if some one here already has tried this one
it's hypertech product

http://www.quadratec.com/products/17614_5001.htm

any improvement specially in low RPM power and torque

[Brent_f70]

Did you ever wonder why they can tell you EXACTLY how much more HP it made in a HUMMER but not a word about how much you can expect with your JK.........it because if they post that number you would not buy it. And I won't buy that...well it's a new product and they might not know yet BS b/c that is all it is BS, they had to do research to build this so they know the HP numbers and are not telling you for a reason.

If you go on hypertech's website it has all the spec's. 11 more h.p. and 24 lbs. of torque.

Good find!! I stand corrected but still not enough of a gain to justify the price in "MY OPINION"

link to the dyno chart... http://www.hypertech.com/media/dynocharts/aa/52001_2007-2008%20jeep%20wrangler,%20chrysler%20pacifica,%202 0.pdf

I agree, your butt dyno will not notice a 5% increase but your wallet will. I think to make the JK come alive you are going to need about 260-280 hp and a 5 speed auto unless you have a stick shift. The weight and the big non-aero box takes way to much hp to make the 3.8 a really useful engine.
Hp is HP and Torque is torque, right? Our 06 BMW has a 227hp I6 and a 5 speed auto. Weight abut the same as the JK. Driving them side by side is a night and day difference. The bimmer can maintain 95+ all day, not the JK. Save the flaming, I'm talking about hp, torque, weight and aero smoothness here. No comparison to rock climbing. You only need a lot more hp and torque if you plan to sustain high speed cruising. the jeep is so un aero that in a decent head wind you have to take it out of 4th gear in to 3rd just to maintain 65mph. If were talking about rock climbing we' d be talking about a completely different issue and the Bimmer would fall way short.

You would need to find out the rear wheel HP also.

i wonder how it works

It works the same way computer programs make your PC run faster, pretty much. It optimizes the computer, changes around the configuration, and that's pretty much it.

And when you run those "MAKE YOUR COMPUTER 80% FASTER" programs, and after you pay $60 for the software and realize it did absolutely nothing.

That's why I wouldn't buy it

[waterboarder]

I've been running without my back bumper for a couple of days now. Besides getting a good 2" of lift in the back, I've also noticed the JK is quite a bit peppier without the rear bumper. I'm considering just leaving it off.

[DennisTheMenace]

How can you really have "best of all worlds" like that? Wouldn't jeep just program the stock computer like that to sell more cars? There has to be some sort of catch.

It's just a device to optimize fuel maps for high octane fuel, Very enticing for myself since that is all I ever use.

It gets it's power and better milage by advancing timing and leaning out the fuel mixture, 91 octane can withstand a much higher temperature before pre-detonating (aka as "Ping") allowing the use of the extra energy normaly wasted for the sake of safty margins and cost of replacing engines under warrenty since users were too cheap to use the correct fuel and start blowing them all up.

As an option it can fool the ECU to do the same with regular gas, most likly since in a marketing stand point almost no Jeep owner would use high octane fuel with the milage we get with our bricks.

It fools the stock programing by lowering the engine runing temp to utilize cooler more dense air and hopefuly not detonate under peak TQ conditions. This increases emmisions so chances are the regular fuel power combo will not pass California emmisions laws and in this mode you'll have the need for earlier oil changes and probably worse milage (marginal) as the engine will not be up to factory runing temp all the time...
Then again you can just revert back to stock programing before emmisions testing if your state/province requires it...

Brent f70: I agree that is pricy for little gains.

Texasdog: as usual I enjoy your comments, & your right.. weight reduction is always the way to go for both fuel milage and power + it's free.

Rirrgang: Reason why BMW is so different is becuase they preduce almost all their TQ @ 1500 all the way up to redline, only the HP increses substantialy as RPM's rise. Jeep on the other hand (with the 3.8l V6) makes it's TQ only in the mid/higher RPMS which happens to also be were the arodynamics would begine to greatly hinder the Jeep past 3rd gear especialy compared to a BMW 3 or 5 series which has lower gear ratio's wich allows them a more drastic increas in speed between shifts, along with their less weight, better arrodynamics, a larger TQ band to play with & more HP to boot too.

thanks for all your replies guys..I had a chance to test JK with new stuff installed..it was Sahara auto..

ok my observetion as follows
1. Adjust Shift Points & Firmness is noticible..specially with auto
2. Maximum Horsepower & Torque oh that is not really true but the torue is slightly shiftted in low RPM which I like it

[dmerc]

Power Commander injection boxes for bikes, are $350 msrp. Looks to me like this does a lot for the money. Don't want more power? Then lean it out, and up your mpg's. I had a 1000Suzuki that could be mapped for power, or economy, using a PC-III. I could go from 35mpg, to near 50!
This makes a lot more sense than a $1000 bumper, or $2000 tires/wheels.

The Hypertech for the JK doesn't have a top speed limiter or rev limiter, nor does it adjust the shift points to where you specifically want them.

You CAN however correct your speedo for gears and tire size, which is the main reason I bought it.

You CAN set it to "tune" the computer to get the most out of it for either 87 or 93 octane gas. The biggest gains come with the premium fuel. I can't say I noticed any HP or TQ gains, but I did notice that with the increased tire size (37) I didn't gain any MPG, but I also haven't lost any, from when I just ran 33s.

So for me, correcting the speedo in and of itself was worth it, seeing as how a ticket and increased insurance would be more than the programmer itself. Getting the same MPG with 37s as I did with 33s is pretty nice too (it's still not great mpg though. lol).

Oh and you can adjust the cooling fan on/off if you've changed your thermostat. I suppose you could do it without changing the thermostat, but I have no idea what this would accomplish.

I don't think it's worth it for anyone who's not going to 35's or 37s and doing a gear swap, but if you're doing those, and have the extra money just laying around, it's worth it. But for about 179 less you could just get the Accupro and not have all the "performance" features of the Hypertech.

[mrsig]

I have it and I think it is worth the price! I can feel a difference!
