(IAT) intake air tempeture

[95 muscle]

i was just given a type or horsepower chip deal. and its supose to pluge into my (IAT) intake air tempeture sending unit. the instructions say "It is usually located in the Air Intake Tube (where the air
flows into your engine) or it may be located in the intake manifold, or
right around your throttle body. It should be a connector /plug with
two
small wires going to it, and a clip on the side of the plug."

now i have a 95 gt mustang, and i am not sure where exactly this is located. so if someone explain to me where exactly the IAT is at i would appreaciate it.

It is between the mass air sensor and the throttle body on the air inlet piping. It's a sensor that screws right into the tube and has a plug connected to it.

The IAT sensor is located in the rubber elbow between the airbox and the throttle body but personally I would just throw that thing away, it is a gimmick that will just try to fool the cars computer by making it think it is taking in cooler air causing the ECU to enrich the fuel/air mixture and maybe let it run a little more timing.

Its pretty much a 38K ohm resistor wrapped with a fancy box and plug-ins, sold for a ridiculous amount of money. You can net the same result for mere pennies for a resistor, which I'm sure you will find, does essentially nothing in the SOTP department. If your car pings, it might help a bit to reduce it, but not really.

Does that come with the turbonator?

so you think its a pointless deal? you dont think it will do anything? i mean i knew it was cheap cuz it only cost me 12 dollars, so i knew it wouldnt do much but you dont think its worth keeping? got any suggestions to help my mustang go any faster off the line. cut its a gt and it takes 10 seconds from 0-60 which i feel is bogus.

I agree with the others. I've tested various resistors and have seen minimal gains. There might be a little after the intial battery reset but once the computer starts adjusting there is little to no benefit.

Im pretty sure that the air temp sensor is not even used turn WOT. I have gone WOT with my car Data logging in temps ranginge from mid 90s over the summer to 50s in the winter and my total timing never changes. If anything the comp may use the ECT sensor but the IAT is pretty much disregared at WOT it is used in Closed Loop operation.

The only good it will do is wide open throttle, and can change the air/fuel ratio, depending on what resistor you choose. I would only use it if you can't get the car to stop pinging at 10* timing. IDK what that resistance will do for your a/f ratio though, nor how much it actually affects it.

If you are not pinging or turning your spark plugs black, don't use it. Snake oil.

I dont know if you noticed my post above yours but the car does not use IAT during WOT runs. I have Data logged in huge air temp sensor differences and never once seen a change in my timing advance. From 50 degrees to 90 degrees nothing changed. It does factor it in during closed loop(not WOT) driving however.

It will hurt your gas mileage and give you no SOTP change.

i wonder if they have bulk discounts on blinker fluid?

i wonder if they have bulk discounts on blinker fluid?

I've noticed the best time for that deal is spring and summer

Now that the temps are starting to cool a bit ......

Look for the price to drop on heater core bushings

I don't know that there is a table in the eec that correlates air intake temp to spark timing. I haven't changed my tweecer setting in a few months so i can't remember. I know there is a ECT vs spark timing table though.

That is why I was saying that the resistor would only be helpful if you are pinging at wot. Timing is not the only thing to consider. lowering the a/f ratio at wot will stop pinging; If you can figure out what resistance is necessary to drop the a/f by 5% or so, that would be enough to stop pinging. I never got that far to stop my pinging, I just bought new heads.

I wouldn't waste my time wiring in that p.o.s.
