Bills IAT sensor mod, reduce temp to 16* for $ 2.89

On the advice of my buddy (and new Hemi driver) Brad, I took apart the variable resistor we tested on the track Thursday that brought the IAT temperature down to a minimum of 43*. I tested the resistance of the unit and then purchased from Radio Shack ($2.89) a 50 ohm variable resistor (2711716) to replace the 10 ohm variable resistor. Hey if a 10 ohm resistor half ass works then a 50 ohm variable resistor should be the ticket. Results:

BEFORE
IAT = 106*
Ambient = 88*
Coolant = 210*

AFTER
IAT = 16*
Ambient = 88*
Coolant = 212*

Maybe someone can test it on the track before I do. Ok, I can see another track rental in the future.
Bill

This looks good. I can't wait to see the track results.

That's what I'm talking about. Any SOTP difference?

Sorry...I don't understand SOTP (its not construction lingo)!

Funny, think I got it. I have not driven it yet, these were garage readings. I would not expect to feel the difference. On the track it is hard to tell the difference between a 12.85 and a 12.95 without looking at the time slip.

I believe that is is only the beginning of "lying" to the PCM through sensors.

what will a cooler air temperature reading compared to a hot reading make the engine computer do?
