Default performance chip?

http://www.performancechipsdirect.com/Saturn/SL/
ok so i kno my car is slow as **** n yes im saving up for the DOHC sawp but in the mean time i thougth id look fer something to add a little more power.
mainly cuz i had a GA n i cant stand how slow my SL1 is when i accel.

i came across the above link and i was wondering if anyone has used it before and if its even worth it? or if anyone knew of another comp. chip that works?

anything helps. thanx.

Don't waste your money on that$0.05 peice of crap . It is just a resistor from Radio Shack that costs bout 5 cents . Buy them on ebay for like $1.99 all day long . All it does is fool you car into thinking that the incoming air is colder than it really is to change the spark and fuel curves .. Keep your money

That looks like a really fancy BS eBay car "super chip" that magically makes the car run better. I think you can buy the "chip" at a RadioShack in their parts drawer.

But yeah, I wouldn't buy that. Looks like any other "insta-power" bolt-on chip. Total BS.

I'll admit being no expert here, but that chip appears to simply fool your car into thinking the incoming air temp is different, usually resulting in a rich fuel mixture. IAT = Incoming Air Temperature sensor

You can build one with under $1.00 in parts, and I don't think you're going to get any realistic power increase out of this little hack.

Save your money.

Oh and to answer the Original Poster's question about "any other chips" that work with the car....Proooobably not.

I believe that the PCM Module on the S-Series cars are pretty cut and dry. I've done some research and most people have come back saying there's no way to "hack" the PCM or "unlock" it.

There is one company that is willing to do work on your PCM (they say they can tune it or something), but it costs $500.

The CARB was so incensed at what the owner could do to the OBD-1 cars that they specked the OBD-2 to be encrypted. The boxes for a couple of the high performance Chevy engines are cracked but you are going to spend 2 large to get your sticky fingers on the software.

There are NO performance chips for Saturn. You can buy aftermarket engine control systems though.

There is a few guys that "hacked" the Saturn PCM. Real advantage? No just lots of coding to change small things. Waste of time.

I prefer pringles. they have more consistant product quality, a convenient storage container and leave less grease behind

They are also hiding that light under a light tight basket.

In reality I think GM created coding to the point it's just not cost effective to bother cracking the vehicle unless it's popular enough to recoup the money doing so.

There are quite a few GM vehicles both OBD I & II that can be custom tuned, but I doubt anyone is going to spend much time doing it on a car no longer made.

OBD-1 is clear code while OBD-2 is encrypted, by regulation. There are I think 2 OBD-2 engines that have the PCM hacked. If you go read the following you will see that its a government mandated requirement. SAE J1930, J1962, J1978, J1979, J2012, J2190, J1850, J2178.

You can get a piggy back type ECU controller and tune OPEN LOOP PCM conditions. CLOSED LOOP, the PCM will learn around any adjustment you try to make.

Encrypted or not, there are a whole lot more than 2 hacked OBDII vehicles. You can get tuners for lots and lots of them. Even the Isuzu in our driveway can get ECM tunes, along with just about any Ford or GM truck made.

With OBD-2 you can carefully remove the PCM and place it in the trash and start over with a decent aftermarket engine management system. These options are always out there but that is not the idea. The idea is to have something that looks to the world as stock untouched by human hands yet performs better. To do that you have to get to the basic tables and fuel maps in the box.

a long time ago, a company was selling a "kit" that included potentiometers [variable resistors] and a cone air filter with a built in velocity. you'd wire the pots inline with the coolant temp sensor and PCM so you could "trick" the PCM into thinking the engine was warmer or cooler that it was and it would add more or less fuel. the air filter whistled! Grassroots Motorsports magazine tested it and it made a bit more power but not a huge amount. It was similar in effect to using an adjustable fuel pressure regulator for tuning in open loop after you installed an intake tube and/or cat-back exhaust system.

Yeah, I'd figure that tricking your car into dumping large amounts of fuel into a car with an unchanged air temp might have some harmful results...like...ruining your engine?

Personally, I don't think effing with the PCM is worth it. Maybe piggy-backing...but that's about it for me.

Oh and I totally agree with the Pringles statement.
