Topic: jet chip pros and cons

[rubberducky]

My brother and I have Identical TJ's 2005 only difference is the doors and color. I have a chip and he does not. There is a vast improvement between the two. Every part we find to state it enhances performance we put it on and test the two. My DD has 100k on it and they were all hard. I pull loads with mine like a genius, and I can hold 70 in sixth while he is in fifth, and i would have a trailor with tires, camping supplies and deer feeders.. I have a olympic fold down light bar and 31's while he had factory tires.  Another mod i found works is, i bought a cone air filter and put it on the intake. Like directly on the rubber that connects to the throttle body. that helped out with response. and also a helix spacer.

Hey rubberducky, how much was yours, where did you get it at, and is it hard to install?  I may consider this if you really thought there was a large improvement in your rig. Where did you gain the most at? Accelleration, torque, speed?  Please elaborate. Thanks, Jeff

I don't know how the Jet chips work in TJs.  I bought a Jet chip, I guess Stage 1, as a gift for my Dad for his first generation "Exploder" close to 10 years ago.  Once we finally got it installed, the best we could tell it seemed to add some performance at WOT.  Otherwise though we weren't so sure.  And he pretty much always ran high octane gas by default after that.   

He still has the Exploder (Has over 300k on it) and the Jet chip is still in there keeping company with a bunch of other mods he did later.  Anyway, I don't think the Jet chip will hurt your engine's life-span.  It might hurt your wallet though (I paid $350 clear back in 1998 I think it was!) Good luck

I run a Stage 2 Jet Chip and noticed a difference right away.  I run a header and open exhaust, a 63mm 4.0, a Hesco tb spacer, auto trans.  I look at it as the icing on the cake...you need to have done a few mods to realize the full potential.  It advances the timing and re-programs the ecu for more driveability...not race car speed mind you but more power overall ...it was more fun to drive once the chip was installed.  It does require some things as a 180 degree thermostat ...and to experience the most benifit...higher octane fuel.  I say the biggest benifit is to those who have the three speed auto trans, as it creates new/better rpm shift points.  So far it has been a good product, easy install (and removal if it fails), not cheap...but then again neither is being bitten by the Jeep bug.

 I bought my Jet Stage 1 it was around $250, it actually moved the power band from starting around 2500 to about 32-3500. I forget where I got it from. When i get back in town I will get back on and let you know, just give me a few days. I was running 225/65-16 getting around 17-18mpg doing like 75-80. Now I put my 33-12.5-15's back on. with my 3.73 its slow, running around 65-70mph getting 13-14mpg. all highway. Its was easy to install, just unplug a connector, plug in chip then plug wire into chip. But yea man, I'll let you know where i got it as soon as i get back home.

 Man I tried to find my receipt or the box, to figure out where i ordered it from but was unsuccessful. I have had it for a year or so, Yea its been a while. The part number for it is Dodge Module Part#90410. Sorry I can't be more help.

  I just found the receipt, it was in the box who would have thought. I got it from Jeep essentials(quadratec.com). item number 17608 21. it came to 279.98 after tax and shipping.

sorry for bumping an older post but just thought i'd point out that part number you are telling Jeff there is the chip for the 2.4  chrysler engine.  Him and a lot of other guys here have the older amc 2.5 which wouldn't use the same chip.

and since i have a stage 1 chip i'll throw in my two cents.  I noticed a decent improvement in performance.  Slight increase in power and most noticeable was better throttle response.  Gas mileage stayed the same for me pretty much..   As for whether I think its worth 250 or not I guess thats up to the buyers wallet.  But for anyone wanting to get any quick and easy performance mod for the 2.5 this is def not something to overlook.

[rubberducky]

Yea man its cool. I said in my first reply I had the 05, guess i should have said 2.4l. But as far as cheap mods, there's is really not a whole lot for any engine. when it all boils down to it if we wanted power we would have bought the six or something else. any who back to work. take it easy.

Today i installed Jet performance chip stage 1 on my 2000 jeep TJ 2.5 liter.
First i installed it wrong as in i didnt fully clip the lock down.
and i also installed the firepower ignition kit today and i noticed smooth running and somewhat power gain,
i could definitely feel slight difference in power but not to bring smile or satisfaction to my face.
and i was totally disappointed in the chip coz i knew the smooth running is from firepower.
then i read the instructions carefully again and was happy that  may be i didnt waste my money on the chip {it was -16 effective today here in calgary and i was in a hurry the first time}
i removed the chip, clipped the lock down , reinstalled the chip and put the -ve battery terminal on again. started the jeep.
so i was little nervous to drive it as i didnt want to discover i had wasted 200$ in chip!!
but to my surprise, the chip really put life into my jeep, i intended to drive for 2-3 kms but couldnt stop driving, i would recommend the jet stage 1 for 2.5 to any one.
its definitely worth the cost.
btw- i have 62 mm tb, 62 mm tbs, dynomax catback, firepower ignition kit and on top of all this jet chip stage 1.
i am so happy that i still can get some more power with electric fan and also grinding the exhaust intake to 62mm.
i will update the fuel economy soon.
right now i am getting 18 mpg- city+highway mixed.

seems like some are actually getting positive results with this. I'll have to wait and see before i throw $$ at it. saving for a regear.

Digging up an old thread thanks to Search.

Thinking of getting a Jet Stage 1.  Don't want to have to use 91 octane with the Stage 2 since the mpg is bad enough as it is.
2.5 automatic, Airaid intake, Banks cat-back.  Will probably get the Banks header at some point and don't mind getting the Jet 180* t-stat.  If I get it I will run 89 octane at least in the summer when we get the crappy oxygenated gas here.

Whaddaya all think?

[sharpxmen]

what's oxygenated gas?
what do you mean by 91 octane and mpg (you mean your mpg will go down if you use higher octane)? As far as i know will hurt with stage 2 chip just b/c will use more fuel to make more power.

[JohnnyO]

what's oxygenated gas?

Gas that has extra oxygen in it to make less pollution.  They make it at different times of the year for different parts of the country.  Here we get it from June 1 to Sept 15 according to the stickers on the pumps.  Some vehicles aren't affected, others run like crap on it like a 3.0L Ranger I used to have that would ping like crazy on the summer gas despite numerous trips to the dealer to fix it.  Most cars and trucks I've owned run noticably smoother on 89 in the summer.  As soon as they switch back to "normal" gas then they run fine on 87.  Also the owners manual for my jetski says to use 87 unless you have oxygenated fuel in which case you should use 89.

what do you mean by 91 octane and mpg (you mean your mpg will go down if you use higher octane)? As far as i know will hurt with stage 2 chip just b/c will use more fuel to make more power.

The Jet Stage 2 chip requires 91 octane.  It must advance the timing.  I don't want the Stage 2 for that reason even though I've done the mods that the Stage 2 is designed for.
