ok, we know the ebay superchip scam doesn't work.......but it doesn't work becasue it makes the computer think that the car is receiving colder air than it is, and if im not mistaken that makes the car run richer.......soooooo if we could make the IAT sensor think that the air is hotter than it is, wouldn't it lean the engine a bit, mabey adding a few hp......or atleast saving some gas.....or is this a crazy idea, if it is, please say so its just an idea i had a moment ago

probably, but then again would you wanna be runnijng hotter than need be all the time....
best to let the sensor do its job. engine techs didnt spend as long desisgning all this stuff for the fun of it...

true, but hey, i said it was a crazy idea. so it would add power, but engine life would probably go the way of the dodo

you would need a wideband to see what's the AF ratio.
Then you have to check the voltage on the sensor to see if you can add some.
it SHOULD work.
you would need to supply power to the wire (AFTER the sensor) to the wire going to the Ecm. Now, the sensor should work on 5v so you would need to find the right amount of power to supply.
You should get a 12v power line from the battery or another power source. Then you need to put a resistance on it to give you the right amount of power.
You need alot of ressistance. I don't mean a big one, I mean a few resistors and test them. What i would suggest is go by .1V at a time. that way you don't lean out the engine.
So if the sensor read 1.5V, you had .1V to it so you have 1.6V witch SHOULD lean the mixture a bit.
Down side - when you get in really cold temperature, you'll have to check your AF ratio ALL THE TIME.
Another thing, I hope an electrician can see if I did a mistake. I'm not sure that adding .1V to a 1.5V line would give 1.6V.

oh, im not going to do it......i was just curious as to wether or not it could work...but it seems to be too much work

In closed loop, the O2 sensor has the final say on the AFR. If the ECM calculates less air than actual, the O2 sensor will show the lean condition and the ecm will richen the mixture accordingly.
In pre OBDII days, IAT readings were often used for spark adjustment more than fuel. It may be possible to adjust IAT signal levels for a boosted engine to retard timing by a few degrees. Although generally IAT plays a larger part at colder temps.
And GM actually goes so far as to calculate catalytic converter temps to prevent converter meltdown, something that won't happen correctly if you alter AFR outside the pcm.
With that said, the place to make changes for mileage and cruising is in the O2 sensor reading. It's actually possible adjust the AFR to around 15:1 for brief periods during light cruise without damaging the converter.

its something in the water NJHK. but i was just curious to see if im stupid or nuts or actually a hidden genius.....turns out im parts of all of them

Not saying your stupid or the people who start these "crazy idea" posts are but they ask questions about getting a slight edge in performance. Also, you have to think that car engineers and aftermarket engineers and all types of car enthusiasts have been working on cars for years on top of years...if there was some type of slight edge in performance that you could do, I'm sure they already thought of it and your probably the million person to think of the idea.
The fact is, big power equals big money. Wasting your time on changing something in you computer this way is pointless. First you need to know if you need MORE fuel or if you need LESS fuel. Second, manipulating the computer is something you don't want to mess with unless you do it properly...not every car will need and run the same with one modification. There are too many factors that play into it. There are big manufacturers who spend lots of time & money on research.

yeah i know......i was more or less just curious to see if the ebay scammers were actaully on to something, mainly from reading one auction where the guy said somethign about 46 degrees being the optimal temperature to run a car at, and he makes sure that the resistor you get will make your car think that its 46 degrees. so i guess the scammers were onto something, just the complete wrong way

They're onto how many people will shell out $$ before doing any research. And they're onto how many people think "It's only a few bucks, if it doesn't work it's no big deal."
Believe me, that resistor trick is as old as electronic fuel injection. With today's tuning and computers, there's almost nowhere to find any magic power. It's really down to the old game of "more power = more air.

there is too a magic trick, just ask harry potter to make your car fast
