Will do.

Speaking of cold it seems to need a slight blip of the throttle to fire up.

Put well over 100 miles on the car today and my code 45 only came back once when I was giving it some good throttle on a hill. Seems to be if I drive like an old lady(which I normally do) the code 45 stays away. Be interesting to see what the computer says.

Random question I've been wondering.....

The wire that goes to the ECM for the A/C signal, does that need a positive or negative wire at my A/C compressor. Only ask because I have both.

AC is a sense wire to sense the 12v when you flip the AC switch on and engage the clutch.
You can use it for the AC, OBA, OBW or just a toggle switch on the dash to apply 12v when you want the rpm to increase. Good for guys with manual trans to use when rock crawling.
But the chip has to be tuned for the desired RPM increase.

Thanks Bill, so 12v positive.

this chip has a tune for the RPM increase
