Was looking around on ebay for some chip burning stuff and found this, it sounds a little to good to be ture. What do yall think?

mod edit: heres a description of the thing for reference when the ebay link dies.

How does this thing work:

The module simply wires into the factory harness of the IAT sensor or ECT. The module will work with the sensor to provide a new signal to your vehicles computer, or ECU. The ECU then adjusts your air/fuel and timing advance curves to new performance settings. Our Prologixx Module eliminates costly parts and installation of ECU components (many ECU mods require you to solder and modify the mainboard), and still safely and legally provides the same end results. There is no risk of damage to the engine or electrical system since the modified sensor signal will always remain within the manufacturer’s recommended specifications. The module works in conjunction with your vehicles ECU and will not affect engine reliability. Installation is very simple. All instructions are included and install should take no longer than 15 minutes. The Module can even quickly and easily be removed or re-installed at any time

 

It just hijacks the IAT signal and allows you to feed a phony signal to your ecm. It won't do a darn thing other than lighten your wallet.

 

the add on ebay says it increases 1/4 mile and 0-60 time? why would you want that?

 

now you tell me! i will have to cancel my order!

 

i better sell all my programing stuff

 

ill take it off your hands if you dont want it anymore

 

The only thing thatll really do is screw up the knock handling on a tbi computer. The IAT has very littel control over the fueling.

 

oh but i goota bid on one of these frist and i well

 

On most cars it tricks the IAT sensor into thinking the incoming air is cooler, which adds more fuel to the mixture or something dumb like that.

Basically it's a 75 cent resistor that you can buy at Radio Shack and slap on yourself, not that you would want to anyways, but for argument's sake.

 

Im not a big believer in this anyway, just thought perhaps some people should see this. Maybe on a newer car it would work with a lot more electronic work but for ours cars I would think the chip burning equipment is the best, that why I was looking around.

If they selling it that high I wonder if i can make one and sell it cheaper. Nah that would be dishonest wouldn't it

You can find anything on ebay.

 

lol...thats funny

 

On these cars its used almost exclusivly for knock handling and some SA control. It even adds more fuel as the temp gets hotter. The knock handling in stock form is pretty aggressive, so maybe an adjustable pot. in place of the IAC wouldnt be such a bad thing.

Basically that thing falls into the same catigory as stuff like magnetic fuel depolarizers (also doubles as a magnetic catch for metal particles), tornado's, Z-Max, etc. Its for people who A) are uninformed and dont know any better, or B) have double digit IQs and wouldnt know any better if you told them so. Judging by the fact that these products are the only thing available now in most autoparts stores Id be willing to guess that alot of people working on cars now are beginning to fall into the B catigory.
