Jet Chip

[Pat]

I'm attemptiong to buy a JET CHIP or whatever you guys call it for a 99' Pontiac Grand AM SE 3400.

The shop who was going to install it has told me that cannot find it anywhere for this engine. Can anyone help.

Thank You,

Pat

If they looked it up as the chip there could be your problem, its the module you want. I have heard some negative things about it tho

[Pat]

Could you tell me any negitives?

Thanks, Pat

Well theres the obvious compared with reprogrammed computers like ASE such as you still have the speed limiter and shift firmness stays the same. But I have heard people getting it and then selling it a couple months later because it didnt add any power (at least by the butt dyno). You can buy it off summit tho......

$200 is a decent price for it

I don't know why people say the shift pattern stays the same. Call Jet and speak with a service rep and they will tell you it does. They say "removes the lag time between first and scond gear to keep the car within the powerband" The Jet item number is68002. It takes about 45Min to install if you do it yourself. If you let a pro install keep that in mind when they tell you what it will cost. Mount it right under the radio next to the cig. lighter. There is a gap behind it to run the wire w/o cutting anything. run it through the drivers side. An upside to having it is the 87 Octane you can run while it is off and only 89 when it is on. I gained 7HP which is proven #. It is an easy removal if you ever need to drop it off in the shop. ASE will void 100% of factory warrenty if they find it in your car. The brain controls all egine opperations so anything engine transmission related will be voided with ASE.

Yes, so I guess the smart thing to do would be to re-install the original chip that gets sent back to you with the upgrades, until the service work is done. (BTW, the Jet Performance Module would be just as much of a problem.)

ASE installs a bus for the new chip to "plug" into, so changing it out and reinstalling the "old" one is a relatively easy thing to do. This is done for several reasons:

- in case of a problem with their chip, the original programming can be reinstalled, and the bad chip can be returned for service;

- when you upgrade the performance mods on your car (TB, intake/exhaust manifolds, supercharger), ASE will similarly upgrade the chip to take full advantage of the new pieces.

One other thing: The Magnusson-Moss Act says that a manufacturer may not deny warranty coverage solely because a customer has used an aftermarket part, unless the manufacturer can determine that the aftermarket part is in some way responsible for the mechanical problem. So stating that the ASE chip will void the warranty is not entirely correct.

There's something else to consider - not everybody has warranty coverage left, so it's not a factor in many members' decisions.

:agree: but a lot of times those damn mechanics will find some bullsh*t excuse on how the mod made something go wrong :mad:

What I was saying is that the "brain" controls all the functions of the engine and Transmission. If you had any problems like burnt rings or bad misfire ect that cause a large problem. They can pin it on someone having the computer not at its original settings to make it run the way it ran. The reason I say this is because I had 2 friends lose there warrenty beacuse of it. If you send an email to GM.com they will send you a list of all things that can and may void your warrenty. It mentions tampering with the ECM and PCM that they can void your warrenty or charge you to reflash it. the 00' TA lost its warrenty through Hypertech, and my other buddy through the GP store on his 01' GTP. It is great that you can put the factory chip back in but I know if I ever needed to take the JET out it would take under 10min to do which is simple enough for me. Jet if left in the card says may void warrenty. Remove before service.

AS I said in my last post, the ASE chip is removable as well - it simply unplugs from the circuit board. You plug in the old chip, put the cover back on, and ta-da! there's no mod.

And since there's no mod, there's no reason for the tech to futz with the 'puter. Having removed my 'puter from the dash once before, I know it will also not take any longer than 10-15 minutes with the ASE setup. The hardest part is pulling it from the dash, and putting it back in - the swap itself takes only a few seconds. And there's no "evidence" left behind, such as a wiring harness leading to nothing, or unexplained wiring splices.

So, really, there is no advantage to owning the Jet box as opposed to the ASE system - except for the price (Jet mod is cheaper - but you get what you pay for), and the week's downtime you have to go through to send ASE the computer. But given that ASE is more flexible and will get you more power, is upgradable, and does everything the Jet box claims to and more, another 150$ and 7 days is a small price to pay.

for you 99 ga it will only give it something like 5-8 hp. ALL it does is trick the computer system. I went to the actual jet chip store loacted by my house in huntington beach cali and that is waht they told me. it will only give you that much hp and about 5 ft lbs of torque. it is really only worth it if yhou have a 3.1 litre ga where it will give it 15hp.
