Cold air = more fuel
 

When the air is a lot colder, your engine dumps more fuel in. I was curious if anybody knew what the magic formula is for when the ECU reads that it's cold out side so it needs to add more fuel to the engine. Is it a gradual thing that constantly fluctuates or does it happen when a specific ambient temp is reached?

It's based on your intake air temp sensor. gradual.

Do they sell different sensors to give you any type of performance gains?

No.

False. Plug-in resistors are available, supposed to be used to spoof the sensor signal. Performance gains range from "zero" to "none" but you lose $ anyway

No.

It's also a "no" because he asked for a different sensor, not a resistor.

Do they sell *chips* to give performance gains? yes. Do they sell *chips* that ACTUALLY GIVE performance gains? no, not for the RD.



for S&G I searched ebay for "sensor performance gain" and it came back with a page full of hits for "chips" even though I searched for "sensor". And I remember when this car was new, until it was debunked, there were "chips" to plug inline with the IAT sensor to spoof it.



IMO: Attachment 2873

I agree with them. When I installed a cold air intake system in my engine, I was actually thinking of installing a unichip which claims to add 10-15% increase of HP, but the truth is that this chips just alter the oem power band of the engine, transferring the power band from mid and high to low and mid and top is almost dead.
