For my 3.7L homies....

I have some info for the guys wanting more power and torque out of their 3.7L. I know that it is just about tapped out and theres not much out there for these engines. But, I have been posting in another forum about the Hypertech programmer and it looks like we might be in luck. I will cut and paste from another forum and bring it here, quoted. Some people do not like Hypertech, but it's all we have for now as far as a programmer. I'll do my best to quote the following in order.........................

It also removes limiters in the program (EI: Rev limiter and speed limiters). He mentioned that if I do a gear swap that it will automatically adjust for it...?... <---I didn't understand that part. I guess when you adjust for bigger tires and the shift points, IDK. I looked in Amazon and it's on sale for under $300 (originally $500), so that's not too bad. Alltho, Amazon says that this programmer will not fit my vehicle, the tech assured me that it will work with my 3.7L QT1 Commander.

For some reason I just don't trust the hypertech, maybe its just me :dunno:

For us 3.7L Guys/Gals it will run you $265, since they don't make cams or heads, etc for our jeeps. Contact him for more info.
**Programmer also works as a diagnostic code reader.

SO FAR
I'm running just the 87 octane tune and the Jeep shifts smoothly, downshifts correctly for power!, and I can only assume it will improve gas mileage when I feather it around town. Hit 115mph in no time... LOL

and this is only the 87 tune! Just put $40 in the tank last night so gotta wait til its gone before i can run the 93 octane!! CANT WAIT!

Contact [email protected]. GREAT GUY"

I thought that someone already had one on an 07 though?

I doubt its that much. For some reason I just don't trust hypertech, it might give a little more power but I really doubt it does gears like they say.

So, I think i will be the ginnie pig if the chips fall in my wallet's favor. I dont have upgraded gears but i do have bigger tires and a sluggish lunch box.

That's it, I hope it makes sense. Basically the Hypertech programmer "supposidly" will boost up the 3.7L +35 hp and also be able to re-calibrate for bigger tires and gear changes. I will be calling Hypertech tomorrow and speaking to their tech support again to make sure that it'll work with the '06 models. On their web site it says "2007-2010" 3.7L. I hope to be able to get dyno runs before and after to see if it actually did anything. So stay tuned and post up your input, concerns, or what not.

Ok, I spoke to Hypertech this morning for confirmation. Well, it will NOT work on the '06 3.7L. :nono: The one they are releasing soon will be for the '07-'10 3.7L models, WTF? Why leave the '06s out of the loop. They said that after the '07 release, they will eventually do one for the '06 models. Bunch of crap, I had my hopes up.

On a good note.....Their speedo calibrator does work for the '06-'10 models and will correct tire sizes up to 44"s and gear swaps up tp 3.70. Plus it's cheaper but does not add hp or torque.

That stinks bro there must be something different in 06 for them to leave that year out. I would imagine if they could of bundled that year in they would of because there profit margins will drop making a stand alone for just one year which makes me think they probably won't ever do it.

Thats what im thinking, why waste time and money for a one year only product. Back to the drawing board.

looks like it is time to upgrade to a newer one with the Hemi!!!!!!!!!!!!!!

Time for a new Commander....you don't need a house anyway!

I opted to trade in the 2006 4.7 for the 2010 5.7 and have no regrets, bigger payment but what the hell. You cant wipe the smile off your face the first time you stomp on the gas. I do spend less on gas in the 2010..............

Thats right join the dark side, the Hemi Side lol.
I do have to say I do love the power & the note from the exhaust it is killer.

Hell, if i had the money i'd seriously consider trading in my 07 XK for a 2010 just because its the last model year...

My commander has so much of my bIood, We are related! I couldn't trade it in.

I would if the car note would stay the same.........but it won't so I'm stuck.

I e-mailed Hypertech with some questions and let them know about my experience with tech support........ Here is their response...

"Caleb

I’m sorry about the confusion must have been a miss understanding on the model year. We all use the same source to find out which products we have available for the different model years, makes and engines. We just recently started supporting the 3.7 liter with our Programmers. We support the 2007 and newer only at this time.
Now we do support the 2006 Jeep Commander with the 3.7 with our Speedometer Calibrator part# 752001. This unit calibrates the speedometer only for tire and/or rear axle changes. Maybe the tech mentioned this so you’d know in case that would help.
The vehicle computer calibrations and VIN are different each year and the Programmer 52001 is not programmed to recognize the 2006 model. I recommend going to our website using this link to enter a product request, http://209.12.144.7/requests.php. We use this list to determine the vehicles we support plus you’ll be notified once available. Thanks

Jim"

I did the product request in the link they provided, hopefully if enough owners would do the same we will get a programmer made for us '06ers.

Spoke to Jet Chips and their programmer will work in our 3.7s.................with a wopping +12hp and +10lbs torque for stage 1..........+17 hp and +13lbs torque for stage 2. I don't see that as a good deal considering the price tag of $250-$300 (depending on where you shop). The cheapest price I found was $228, which makes it out to be $19 per HP for stage 1. Not worth the while in my opinion, plus Jet Chips has some bad reviews on-line.

SO, I ordered the Hypertech speedometer calibrator to correct my tire size issue and hopefully it will correct my "hunting" for gears while on the highway. I will post up in my garage when I recieve it and install it.

Any news?

if you are talking about the speedometer calibrator, here you go------> Hypertech Speedometer

bumping this back up. my friend is looking at programmer options for his 2006 3.7L WK....

link above doesn't work due to site changeover. can you add your experience to this thread?

Matt. I don't think anyone has it yet. Ill find that email and post it up when I get home
