I'll make you one for $15 lol

 

Hate to disagree, but the manual states otherwise.

This is an Open Loop mode. During engine warmup,
the PCM receives inputs from:
² Battery voltage
² Crankshaft position sensor
² Engine coolant temperature sensor
² Intake manifold air temperature sensor
² Manifold absolute pressure (MAP) sensor
² Throttle position sensor (TPS)
² Camshaft position sensor signal
² Park/neutral switch (gear indicator signal—auto.
trans. only)
² Air conditioning select signal (if equipped)
² Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
² Voltage is applied to the fuel injectors with the
ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by
turning the ground circuit to each individual injector
on and off.
² The PCM adjusts engine idle speed through the
idle air control (IAC) motor and adjusts ignition timing

 

I have the powerwire and a wideband. The a/f does not change at partial throttle with the powerwire or without. I tried both and it is still right around 14.5. Next I am going to try it WOT and see if the a/f changes any with the powerwire vs. without the powerwire.

 

Will be interesting to see what your gauge displays since airram says, "

 

I would think that it has to have some effect at WOT, but I don't know if it going to be as much as they say. Guess we will see.

 

This is excellent evidence at what point does the PCM go close loop. Maybe only 20 degree drop is not enough to have the PCM go open loop. I don't know. If you can read the engine from a cold state perhaps it will become known. Or if an adjustable resister could be installed and monitored while adjustments are made.

 

THIS REMINDS ME OF THE ARGUMENT i HAD ABOUT THE LITTLE BLACK BOXES FOR $25 BUCKS ON EBAY THAT GIVE YOU 100PLUS HP BY ADDING IT TO YOUR TRUCK. LOL

 

you need to take that tonno out of your sig lol

 

I've got one thats been in my center console for over a year now, you can have it. I did some 1/4 mile times with it on and with it off NO real improvement, little more tire spin out of the hole . Also in the summer month's I found no real mpg increase and from what I understand it's worthless in the winter because of the cold temps.

 

As said before, the P/W will not give better mpg. The ONLY thing that is going to do that is keeping your foot out of it.

I mean seriously, look at my mods, Ive got an efan, ALL synth oils, gearing, ported heads, LTs, CAI, tuner and more and still no better mpg UNLESS I baby it. The bad thing is thats not fun once you have done everything I have.

The P/W is for fun at WOT only.
