anyone have one of these jet chips installed on their 4 banger? here i am again in effort to squeeze out as much HP and maybe a few more mpgs from my jeep. does this thing really work-will i get a few more hps and mpgs from it? are there any dangers? im lookin at the stage 1 chip and i already have an AEM cold air intake, 62mm throttle body, TBS, and dynomax ultra flow cat back....all these mods have done a bit-not much in the range of HP increase and mpg increase...any opinions would be much appreciated.
-
I have one. IMO, it wasn't worth the money. My stage one hasn't really shown me any difference from stock.
-
yea i was wondering if it was too good to be true-figured for $250 it prob would be $250 spent on very minimal-if any-improvement...wonder if anyone has actually gotten positive results from this chip
-
IIRC the general consinces is that the stag 1 chip wasn't worth it but the stage 2 gave a better response for the $$$..... but its been a good while since chips have been talked about
-
If you cross many rivers, keep in mind that the chip can cause some problems; a friend of mine had a stage 2 on his 6-cyl, and after crossing a river, the ECU went haywire as a result of the chip... I dont use any chipes (none available for the 2.5L YJ), so I am only telling you what I was told and have no personal experience with this matter...
-
stageII seems to want a new theromostat and for the jeep to burn 90octane....a bit pricey. maybe if this offered a good mpg improvement it may be worth it.
-
I put a stage I on and saw an improvement that was worth the cost. My guess is that the guys that didn't like it only had the chip not other mods. For me it really pulled the CAI, header, TBS, 62mm TB, electric fan and mustang injectors together improving overall performance.
-
and as for fuel efficiency which it is advertised to apparently improve....
-
Coulnd't tell you, not a daily driver don't keep track of milage (not that it would be super acurate anyways).

I had one on my TJ, a stage one, and it was a waste. Once i started adding more mods it started going crazy and i eneded up taking it off. Gave it to a buddy and he loves it but his motor is stock. If you plan on adding engine mods just steer clear of them.

I'm no expert by any means, but in the past on my other vehicles I modified, I would always disconnect the battery evertime I did a new mod. This way the computer would relearn any new info it was recieving. Did you do this?

Although I can't get any chip for my YJ, I've ran a JET chip in two of my previous '91 S-10 Blazers, grantd it was a Christmas gift I noticed a difference in power/mileage with it. I blew the motor in my first S series and hadn't sold the chip yet when I got a second one almost a year later, so I swapped the chip in first thing and noticed a difference. The improved throttle response was what I liked most of all.
We ran the Jet 6-pack in our old '89 TBI Chevy for towing, and it helped a little but always had a problem with pinging when we towed, so we would just run 91 while towing...

Yes I did when i first installed it and every time i added a new mod. After i added teh 4.0TB and intake tube the stage one jet chip didnt seem to like the increased air and was giving me running problems. Before adding all that it ran fine. my problem was afterward. The stage one is only for stock or slightly modified engines. When you start playing around with intake mods the stage one didnt like the change. Like i said my buddy runs it and loves it on his stock 2.5l.
-
in that case i really dont think its worth it for me. im runnin a 62mm TB, a tb spacer an AEM intake, and higher flowing exhaust-id need to go to stage II, but it seems with stage II ya need to run higher octane and it doesnt seem like you would get better mpg. more expensive gas for same or maybe less mpgs......not with the price of gas these days..i think ill pass.
thanks for all ur input guys!

I thought that a 4.0 T.B. and intake tube was only a slight engine mod. Seems to me like these kind of bolt on items are hardly any more than mild. A cam, shaved deck, ported head and valve job, headers and maybe some sort of forced induction would be more a modified engine to me.
I have a 4.0L T.B. along with a 4.0L air tube with a k&N drop in. I think the 4.0L air tube flows much better than the stock 2.5L setup. I'm also running a set of MSD wires with a Scream'n Demon coil. These mods made a good difference as far as the butt dyno goes. If I remove my Jet Chip and run it through a few cycles to reset everything, I don't notice any difference in performance or gas mileage as compared to when it's installed. I'm not saying everyone has or will get the same results. Just relaying what I've found with my mild setup.

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.

Jeff
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.
-
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?
-
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.
-
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.
