Sensor mod

I just traded in my 05 Escape for an 08 edge. The Escape was great and I ran it hard 90k and never did anything but maintinence. One thing I did that actually worked very well on the V6 it had was to install a 10K ohm potentiometer in series with the air inlet temerature sensor. For some reason it really helped it unlike doing next to nothing on other engines. I used a pot from radio shack and turned it up till I felt it and thats all it took. Maybe a good start would be 5K but just twist it around till you feel it being more responsive and no more than that. You will need to poke around with your ohm meter to find the wires. Next wire the pot in series with one wire that goes to to the air inlet temp sensor. The sensor is just a thermistor (varies resistance with temp change) My wife could tell when I turned it up and down and she's ...well just a woman driver. It makes the engine think it's colder outside and provides a timing map and fuel curve for an enviroment that has denser air. It really works on an Escape better than any engine I ever fooled with. I live at 6000ft elevation if that makes a difference or not to why it worked but on my jeep 4.0 it did nothing.

So you ran it rich all the time...

Proobably not good for the Cats
Probably no good for the EGR stuff
Definatly no good for the enviroment
Definatly no good for your wallet

Whaa. How much do really think the computer compensates when it thinks it's 20 degrees colder out side? It did not efeect milage one bit that I could tell but you could tell evertime you stepped on the gas. It made the throttle way more responsive but if you like the no-brainer lag factor built into these rigs and have no desire to let your foot have more controll on vehicle operation then this mod is not for you.

I stand by what I posted earlier.

Oh, and I got a REAL electronic tuner for mine. Could chirp tires (18" ers) going into second gear with AWD. Lets see your overly-rich smoke-bellowing truck do that.

During cruise, the Oxygen sensors would tell the computer that its running too rich and lean the mixture out. The air intake charge will have some effect, mainly during start up and heavy acceleration, but the computer will eventually learn the sensor and compensate.

You'd have to run ungodly rich for it to have black smoke come out the exhaust anyways. It wouldn't even run right if it was running that rich.
