Ebay Performance Chip

yea i saw them and they look to be a scam. They are just trying to get peoples money. I was at my local shop and we were talking about them and they dont do anything. Just people trying to rip people off for a little money. dont waste your money.

I would stay very far away from that. Stick with product well known products unless you feel ventures to try something new. I would go with SCT or Diablosport. They will get the job done.

well known names are best

The resistor "chips" are a scam.

The funny thing is that they actually work for a little while. How it works is it fools your car's computer into thinking that the intake air is a lot colder than it is (like 30 degrees F). The computer responds by advancing the timing a hair to make use of the denser air to make a little more power.

The problem is that at the same time it commands the fuel injection to add more fuel to maintain the right air/fuel ratio. Since your intake air is not actually at 30 degrees, the mixture will be way too rich. Besides wasting fuel, you'll be loading up your spark plugs and cylinders with carbon, and since the computer is confused that it's not able to adjust the air/fuel ratio properly (O2 sensors aren't agreeing with intake data), you'll eventually get a check-engine light.

Another side effect is the possibility of detonation with the advanced timing. A colder intake charge tends to inhibit detonation, but with warmer air any detonation will trigger the engine's self-protection feature that retards timing, undoing the gain you got in the first place!

In short, there's no free ride!

I've had that silly "$1.00 plus shipping resistor" on my car since 2004, yes, I am a fool...
Noticable performance change...NO
Hurting what performance I had before the resistor......NO
Hurting my gas mileage....PROBABLY
Bringing up a CEL.....NOT FOR THAT, ONLY FOR A FLOODED/SHORTED AIR PUMP
I'd say, don't bother, if I could find the original IAT sensor, I'd put it back on, but I won't buy a new one...yeah, not only a fool, a cheap fool
