View Full Version : Gas chips that remap fuel/air ratio on eBay and other sites

I normally run 93 in car all the time even tho I'm 18 and treat the car like its my baby. Still in high school working part time 30 hours a week. Yes its a lot for 93 gas Hahaha. I read in manual that you need to run 93 I'm car. What does everyone run? For all year Cateras people!!! I got a 1999

Premium 93 octane is recommended, not required. Reg 87 octane is fine with only a slight reduction in power. I've used it in mine for 6 years with no problems.

Wow! Okay thanks man!

Does anyone know where I can get one? Or purchase one online?

For these Cadillacs I seriously doubt there is one. NOTHING for the Seville/Deville/Eldorado lines. Nothing.

There are no chip upgrades or reflashes for the Catera. Don't waste time searching Europe either. Their CPU is completely different. The only engine upgrades are the free-flow air intakes and exhausts. Search ebay.

PS: the so called chips on ebay are nothing but a resistor to fool the cpu that the engine is cool and needs extra fuel to raise its temp.

Get the car 1500 pounds lighter. No speed chip needed

...It was a joke.

Any thoughts on if they would work

1999 Cadillac Cateta
Should I use 87 89 91 92 93 Gas?

Gas requirements in the owner's manual, use no snake oil.

"Chips" are usually a scam - a plugin 25 resistor that fools the intake air temperature signal into providing a rich fuel/air mixture.

Some of the Catera tuners in this forum may have other tricks.

You already posted this in another thread, so I merged the two. Please do not double post the same questions. Let one thread do the work for one question. Thanks.

I'm trying to save gas. Not increase performance

You'll do the opposite of both with a "chip".

Accelerate and drive slower.
