This is obviously a load of crap:

It is a resistor that fools your engine into believeing that the intake air is way colder that it really is. The ECM responds by giving the engine more fuel. There is a small power gain, but also a small loss of MPGs. You don't see very many of these things anymore. kinda died out around Y2K.

 

if you wanted to try this, get a resistor (i'd have to look up what size) and place the leads into the IAT sensor harness plug. Tape it in place and go for a drive. The resistor is about 1.50 for 5 or 6 of them.

Definitely a rip off on ebay.

 

The guy's spelling and grammar is horrible in the auction.

 

haha yeah.....not very professional looking packaging either

 

I love your Sig. That's my motto too.

 

Truth is, it looks like a piece of coaxial cable.

 

Has anyone ever tried this product or one like it? How much power WOULD you gain? When it comes to aftermarket performance parts for bikes and sleds you generally pay $75 to $150 per hp. E.g. A full exhaust system for a bike will run you $1500 - $2000 and you may get 10 - 15hp.

 

This is just another rip off.

Why do you think the edge cost $450 for 35 hp......?
This cheap mod will not give you more HP than the edge.

Wish they'd quite making these things.

 

eBay keeps trying to make these auctions against the rules, but these people are very savvy at skirting the rules marginally.

but yes, the resistor is crap, and potentially very dangerous for your vehicles electronics

 

Nah, the resistor isn't dangerous. no more that the adapters to eliminate the rear O2 sensors. Those are resistors too. Just fools the computer into thinking they're on the car and operating correctly. All the sensors on our trucks use resistance to give input to the computer. Even the MAF uses resistance to measure the air flow across the fine wires in it.

 

What is with all the resistor chips on ebay? Do they do anything?

 

Look about 8 threads down the list:

If I remember correctly I think you can go down to the 7.3 diesel sections and they basically make there own (stuff from radio shack) and they seem to work. Now I would not do it to these trucks unless I saw some real world stuff on it.

 

Thats what ebay is for, make it and sell it on ebay to see if it someone is dumb enough to buy it and try it. And if they say it works great, then maybe you can try it for yourself.
