Hello all,

Just wondering if these "Intake Sensor mods: you find around Ebay
really do work?  Here's an example of one that's listed right now:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2452335449&category=40926

From the picture, it doesn't look like anything more than a resistor
jumped across two pins of the intake sensor module.  I tried searching
google to see if I could find any info on this, but came up short.

So if anybody has any experience with this, please post a reply.  And
if it is nothing more than a resistor, does anyone know the exact size
of the resistor needed?

Many thanks in advance  :)

wow ,

starting bid for a 1/4 watt resistor is six bucks ?!?

gimmie a freaking break.

I guess P.T.Barnum was right, "there is a sucker born every minute"  (this
is no slam against you)

This is the oldest trick in the book, it will NOT give you any more
horsepower and it Will decrease your average miles per gallon.

What you are basically doing here is "tricking the air flow meter into
thinking a greater ammount of air is moving thru it and the ECM tries to
compensate be increasing the injector pulse width.

don't do this mod . leave your pathpuppie just like it is and it will give
you many years to good service

No sh.t ! I can buy a 100 of them for 5 bucks.

Wan't more power ? Buy a pathfinder with a 3.5L motor. Or trade it in on a 275HP
Chevy Trailblazer.

In layman's words, wider pulse = more fuel per squirt. That doesn't = more
horsies since your puppy needs to breath better.

Umm I don't share that opinion :)

Yep... no doubt a ripoff.  I'm an electronics tech by trade, so when I
saw the resistor I figured he was simply jumping two points of the
sensor together -- and using the resistor to compensate for either
voltage or current.  

I ended up coming across a few posts on nissanforums.com regarding
these little homebrew mods... and just as you had mentioned NissTech
-- basically just a bullshit mod that doesn't work :)

Many thanks for the reply... much appreciated!!

PS - Are there any reasonably inexpensive mods to be done to the
pathfinders to give a slight HP increase?  I should be content at
240hp, but you know how that goes... the more you have the more you
want  ;-)

I put on the SLR Air system and Exhaust on my 03 Frontier
Am putting out almost 200HP and 218TQ. Estimated as you know due to no real
way
to ensure flywheel Pwr unless we pull the engine.

And they call it a Speed Chip. They go on to say that this "secret mod"  has
been used by many drag racers on the track. What a load of bullshit. I have half
a mind to email this crook.
