any one heard of taking the wires from the intake tempeture sensor and wiring them together so there would be no resistance and fooling the ECU into thinking the air temp is cold?

could you actually do this without any other modification? and would it be safe? i've thought of doing it and running a switch to it to switch if off during normal driving.
i know you can do it with a resistor, but would it hurt to straight wire it?
would my ecu just think the sensor is bad or anything?
my car has much more get up and go when i first start it cold than when its hot.

btw, if you do have to have a resistor what resistance would i need? i got alot of old computer parts, im sure i can get one off there lol

well
imo i think it would hurt the ecu...or possibly causing the check engine light to come on.

beside it's like a temp sensor...i belive the higher the resistance the hotter the temp...so if you put in a low resistance resistor it trick the ecu to run richer.

what i plan on doing is moving the iat close to the a/f airfilter because its real cold.

Yea they are on ebay from anywhere of 6-30 bux. Its a 5.1k resistor that you can get at radio shack, their like 3 for a 1$. I was thinking about runnin up to RS and getting me one. The only thing it would make the computer think is its getting cold air only......? I think I might be ginnie pig....I need some more info though.

what do yall mean by moving the sensor? are you plugging up the hole on the intake manifold for it?

really what i did was leave the old sensor in the intake manafold and got one off of and 3rd gen accord lx/dx.
since the wiring and sensor was the same i thought cool.

but it's not i was looking at my current fuel eco.
and at 60mph it went from 33,32,31 and so on.
i was like at 17c.f.e.

and it works.
but today as i had the engine running i thought :
wait the sensor is mounted on the driver front......
which is closer to the t/b.... and at a cool spot.
and with me putting on the cai it made that port even cooler.
so i put it back it seemed to idle better but i have'nt driven her yet.

ok, well i tried to use a 2.5ohm resitsor off a circut board i had laying around and the ecu took it, but the car seems noticibly slower for some reason..

well thats because it's probably telling the ecu that the temp is real hot...so it's leaning the mixture.

try i lower resistor.
i think if it's too cold(resistance too low) it might hesistate....
