It will do absolutely nothing for your 2002 Ranger. It has a small effect on some vehicles but the sensor output they're modifying won't help yours at all.

 

You could buy a resistor at radioshack for 2 bucks and try it yourself.

 

You could prolly get the resisistor for 17 cents..

True but I'd rather have my 17 cents. That mod doesn't do anything on a 2002 Ranger.

 

just the fact that it is on ebay and it is being questioned doesnt give me a doubt to its BS-ness...

 

yeah I was going to say for $2 you could get a big pack of them.

 

And hook em all up in sequence? Instead of gettin a low degree on your computer, you could get like ohh...-459 degrees below 0. That's what my truck runs at. Only problem though, since molecules stopped moving my truck doesn't actually move anymore...it's all good, the A/C its great!

Aaron

 

I was just saying that resistors are cheap and you don't have to buy the off ebay.

***** holders...

 

Right, and we are just agreeing with you.

 

I don't see how this would work anyway on any year truck. Your truck can only get in and out so much air. Sure you can lean out or make more rich the fuel and play with the timing and stuff but only so much and I would relay on a chip to do that over some make shift thing like this.

You only get what you pay for !

 

Many people think that this mod has something to do with A/F mixture. Not true. Actually, the principle is that a colder intake charge can tolerate more spark advance.

In earlier fuel injected Rangers, and in many FI vehicles in general, the Air Charge Temperature is used as an input to the spark calculation. So, if you tamper with the Intake Air Temp sensor's voltage input to the PCM, it is possible to fool it into thinking that the intake air charge is cooler, causing it to advance the timing. Advanced timing produces more power IF the fuel can support it without excessive detonation. In calibration strategies that use the ACT in the spark calculation, the combination of a correctly altered ACT input and high octane fuel can make a small but often noticeable power increase.

Now, back to reality. A 2002 Ranger does not use the ACT in the timing calculation of a warm engine. So this kind of mod is totally pointless.

 

Hey Rwenzing, how does temperature affect it then? But my truck is a 99 Ranger, and when I drive it up here, it will be -40 degrees below zero at some points.

Aaron

 

I don't know whether your 99 truck still uses the ACT as an input to the spark calculation when the engine is up to operating temperature. If so, the temperature based spark adjustment is a combination of the ACT and the ECT (coolant temp) and there is a clip on the maximum effect either or both can have.

 

You could get the same effect with a chip though right ?

 

There are literally thousands of adjustable parameters in a calibration. Someone with access to the program can change the base timing or its modifiers, no problem.

 

Right which is why even if this did work on my truck i think i would just get the same effect with a chip.

 

Actually, there is the potential to gain far more from a proper recalibration than there is from something as crude as the IAT resistor mod. Of course, you would probably expect a bit more from something that costs hundreds of dollars as opposed to a few cents.

 

Right, something like this seems to crude for my comfort. I don't have a problem paying for a quilty product over a crude little fix like this.

 

Didn't John try this out.. decide it was the cat's meow.. then end up eating is words when he found evidence it did nothing for his late model truck? I'm sure there's a series of very well documented threads around here somewhere..

Be sure to read the entire thread before coming to any conclusions based on the first posts. There is an evolution to it that ultimately confirms that the mod does not work on the newer trucks.

 

wtf!? I have never evn seen such a cheap thing!

 

Because its JUNK.....


haha there is this dumbass kid with a zr2 s-10 (completely stock) that graduated from my school and he was tellimg me "yeah dude, i found this chip on ebay for like a few bucks, thats going to give me like 25 horse power!!!"

I laughed in his face.
