Bought a Crap Gimmick -- What does it do?

So, I picked up a "Pro Choice Performance Module" for my car, because I've been a little disappointed by its pickup. I had a hard time believing the claims the seller made, but I figured that for what I paid, even if it did nothing at all, I was only out twenty bucks.

So, it showed up today, and this thing is supposed to replace either the Intake Air Temperature Sensor or the coolant temperature sensor.

I don't expect it to do anything, but will it actually hurt to hook it up? I can't imagine how twiddling with a thermostat could have any kind of positive effect.

WHat is this thing *supposed* to do, and should I bother installing it at all?

There's all sorts of "performance" modules out there..

if it's the air temp; by telling it it's colder than it really is; more fuel will be dumped in (air will be more dense, hence requiring more fuel).

there's ones that do O2 sensor mods -- basically they lie to the computer to get the computer ot pump more fuel in....

anything short of modifing the injection map and / or ignition map is a waste of money .... That's just my HO

computer to get

So, if it works by claiming it's colder than it really is, could that lead to the engine overheating?

I realize that's probably an incredibly naieve question. More or less everything I know about cars, I learned from my dad, who couldn't keep up any more by the time fuel injectors were a serious option.

I'm not even exactly sure where to hook this thing up. My repair manual hasn't been much help (At anything, really. I've always preferred Chilton, but I can't seem to find one covering the '98 Legacy, and had to go with Haynes instead, which I'm sure is a fine manual, but it's awfully thin for the number of models it covers)

Move 20 bucks from your pocket to his :0

doubtful; more than likely you'll just notice your fuel usage go up and your spark plugs foul faster -- you may eat up a cat quickly too.

I would advise you to toss it out.
