resistors?

One of my buddies was telling me about a "50 cent resistor" that will add like 20 hp. I was reading about these and found out that you put them in your intake and it tells your computer that the air temp is like 30 something degrees. anyway i need to know if this is true and if it will mess up anything.

read the FAQ sticky thread.

here are some posts about those piece of crap resistors:

It's a POS if you pay $20 on ebay, and it's still a POS when you only pay 10 cents for it at radioshack. Save your money. There are no gains to be had.

yea, only thing it does is make your car run leaner since cooler air tells the ECU not to dump as much fuel in. Definitely not a good thing to do on a turbo car, and still wouldnt recommend it on an N/A car. If you want to lean it out, do it properly with an S-AFC so you can control how much you lean it out instead of a resistor guessing for you.

Wouldn't recognition of cooler air tell the ECU to dump in MORE fuel, to prevent lean conditions, ultimately causing the car to run richer? Or am I too tired to think straight?

we're all tired :p but no, it adds more fuel as the temperatures rise because more fuel cools down the engine temps. When the temp falls, your engine can handle a little bit more so it takes away a little bit of fuel. Main reason i know this was it was part of my predetonation problems with the MAF-Translator. The MAFT, along with other airflow sensors such as the arc 2 do not include a temperature sensor or a barometric pressure sensor, so the ECU thinks its the same temperature all the time. When the temperature increased, my engine predetonated because it couldnt overcompensate for the increase in temps, which is why if you have one of these, either you need to tune it be what time of year it is, or tune it in the hot weather and run a little bit rich in the cooler weather.

interesting. nice piece of info to have there. so have you solved your problem by just tuning it according to the weather/seasons? or haven't you gone with a new setup?
