Correction...IAT, not LAT

Recently, I have been browsing Ebay and stumbled across a very inexpensive performance upgrade. It's a resistor that you install in your LAT sensor which will supposedly give you about 25HP gain.

THIS PERFORMANCE MOD WILL CONNECT TO THE CARS INTAKE SYSTEMS IAT SENSOR. ONCE THE MOD IS INSTALLED, THE SENSOR WILL READ A DIFFERENT AIR TEMPERATURE THEN WHAT IS REALLY COMING IN.  ONCE THIS GETS RELAYED BACK TO THE ECU IT WILL ADD MORE AIR AND FUEL TO THE CAR, GIVING IT THAT EXTRA HORSEPOWER AND TORQUE THAT YOU ARE LOOKING FOR.

Does anyone know if this works and if it's safe and what size resistor it takes?  

It does not work and can cause you to get towed home!

I bought one....it currently resides somewhere in the gravel driveway where it landed after I removed it....

tell me this.....does your engine feel like it has 25 more horsepower in 30 degree weather tha it does in 90 degree weather?.......uhhuh..thats what I thought!

its a good theory but bunch of BS all it is...  

well i won't install it then, it seems a little sketchy anyway. are there any good computer chips/programmers that work?  

just for kicks and giggles your jeep with a 4.0 produces about 12 more hp when its 30 degrees rather than 90 (if your jeep makes 190hp at 90 degrees F which it probably wasnt dynoed at that temp from the factory)  

lmao  

actually mud. an engine makes 1% increase of hp for every 10 degrees you drop the air temp. if its making 190hp at 90 degrees (which it is probably not, mopar probably dynoed it at 50 or something, but lets say it was) then it will make 1.9 mor hp for every 10 degrees you drop the temp. 1.9, lets call it 2, the diff between 90 and 30 is 60. take 2 times 6 and you get 12. im saying this is in a perfect world where the humitity and everything is just right. check into things before you call bs.  

so I coulda got the 12hp lawn mower an use it when its cool out and it'll work as good as the 16 hp always does?  

lol thats a great flag! i pleadge....  

not what i said mud. if your lawn mower puts out 12 hp at 90 degrees F it will produce .72 more hp at 30 degrees F. its simple math if your engine puts out 200 hp at 90 degrees F and you are wondering what it puts out at 10 degrees F you would take

200 x .01 (which stands for 1%) x 8 (which is how many increments of 10 that we went down from). you are now producing 16 extra hp at 10 degrees F.  

why do you think in hot rod magazines they will put 600 hp(corrected altitude) that means they have a standard that all can follow so someone in minnesota cannot brag on a dude from texas with identical engines with same mods.

heres a way to prove this. take a balloon and fill it up with air, then put that same ballon that is full in the fridge for a while. take it out and it will be smaller. take that same ballon and put it from the fridge into the freezer, wait a hour or so and take it out it will be even smaller than before. then leave it out for a while it will get go back to the size you started out with. the same amount of air was in it the whole time, granted no air leaked out. this happens in your engine because your engine can only put so much air in with out forced induction, thats why it helps when its cold outside, because the volume of the engine takes in only so much volume of air in but more volume of air when its colder.  

i am in no way saying that the sensor mod will work i am just stating the facts about temperatures. i dont doubt the resistor mod is a piece of crap thats why i dont have one. im just stating that when its cold, you have more power. thats a reason for drag racers to put ice packs on their intake manifolds.  

lol...I fully understand the temps and bought the resistor, because it makes sense,
what happened was really poor mileage, no power increace and a tow home, after I took it off and reset the computer the engine light went off and it was back to normal..on  forced induction it is important to have a cool charge air, for naturally aspirated daily driven engines its a bad joke, I do have a cool can on the chevelle for fuel...ya see causing trouble is what I'm really good at!  

so your saying that what i said doesnt apply naturally aspirated engines?  

I'm sayin unless you're racing or grasping for numbers on a dyno it's pointless.. we don't drag race in a controlled enviornment...on that note how bout we fool around with the altitude sensor to?

at what rpm range is the gain usefull and what else is getting the incorrect signal that causes an undesireable effect?

anyhow theres no question that cold air makes a difference..when a sensor is telling a ecm the air is 30 degrees when its really 90..we have a problen  

if your asking me this, why did you buy the mod?

“Normally aspirated engines really respond well to cold clean ducted air from out side. It’s the theory that most of the factorys used when they came out with big hairy hood scoops, ya know, during the muscle car era, well that and they look cool.”
Gale Banks
“That’s the whole idea of ram air, cold air at the highest possible pressure, the colder the air is the, the more power ull make”

all im saying is cold air will yield more power bottom line.
