the sensor is called the IAT sensor and im supposed to put a resistor lookin thing into it but i cant find this sensor???????
where is it??????


Yea thats must be it on the directions it says IAN.......but yea i cant find this plug to put the resistor in does anyone know where it would be located on the intake manifold the car is a 98 accord ex SOHC f22...........to the dick wadd.........i got plenty of ppl who know what im talkin just dont be a dick and try to help your fellow tuners

Are you talking about the IAT? Intake Air Temp sensor? Is this on a Lamborghini or a Ferrari?

 

wtf are you talking about? can you please give us a little more background? your post made absolutely no sense.

 

Bwahahahahahahahahahahahahah!!!!!!! Bwahahahahahahahahahahahah!!!!!!!
*****takes deep breath*****

Sorry, umm, yeah, are you talking about the IAT? because that's one of the only things i can think about that you would be putting a resistor on.

 

its on the manifold should be white or black colored. but why are you trying to run a resister to it?

if you put a resistor on it and change the values it throws to the ecu, the ecu will throw a little more fuel in the mix. But that's only when the ecu is in closed loop mode

 

If you have a 98 accord ex, you do not have a f22. you have either a F23A1 or a F23A4. it's stamped on the block left of the headers.

It's that trick they sell on e-bay. basically you put a resistor on the IAT sensor so that the ECU thinks it's colder than it really is, and it advances your timing i think. At any rate, it does something, or maybe nothing. never tried it, but it's supposed to make power.

IAT sensor is on the end of the plenum, directly in line with the throttle body.

it's #11

 

I hope you're not calling me the dick "wadd". We have to figure out what part you are talking about... Then you expect us to just figure out what kind of car you have? I do help my fellow tuners when I can, if they don't ask a retarded question. Maybe you can ask your "ppl" what kind of engine you have.

i wasn't speaking to you if that's what you thought.

 

I was referring to the original poster....

 

whoooooaaaaaaaa,,,,,, this is a weird thread.

So if I put a resistor on my IAT output it will drop the voltage signal the ecu sees from the sensor? How many ohms and what power resistor?

F23 IAT sees between 0.1 and 4.8 volts.

Ohms law states that Voltage(V) = current(I) x resistance in ohms(R)

so V = I x R
or R = V/I
or I = V/R

measure the Voltage seen at the IAT, then measure how much resistance the IAT has. solve for current. decide how much of a voltage drop you want and solve for resistance. bingo, you have your resistance. I'd be willing to guess that a 1/4 watt resistor would be fine.

 

Certian value resistors can be used to trick the ECU into thinking the intake air's temperature is colder then it actually is and the ECU would then dump more fuel in to compenstate.

The eBay way suggest cutting the sensor out and just replacing it with a set value resistor. That's a big no no.

If I where to do this mod I would either use a resistor inline with the sensor just to richin the mix some but still maintain the IAT's functionality or use a varibale pot resistor in line and change the value on the fly, that way achieving the best result.

Personally I'd rather not mess with an ECU sensor input I would much rather rewrite my fuel and ignition tables so I could get consitant power gains threwout the powerband and still have a fully functional IAT to adjust for temperature changes.

If you live in a climate where it doesn't get very cold you could bypass the throttle bodies coolant supply. That would make for cooler intake air.
