well i saw this today on ebay, and was wondering if anybody has tried it. im still confused on what exactly it is?

:disappoin :screwy: :disappoin

It looks like it's supposed to be a chip for the ECU, except this one is external. I like how they never actually say what it is, makes me real confident in buying one.

it looks like somethin thats for an old chevy that replaces the condensor in the distributor cap.... but :dunno:

Looks like snake oil to me. I'd stay away.

...dont be a sucker :nono:

it prolly gives as much power as muffler bearing and halogen headlight fluid do.

ok, i just bought one of those last month, not the same name, but it looks just like it. I haven't installed it yet because it changes the fuel ratio, and I have an emission test next month :nono: :banghead:

Let me quote what they put in the instructions, just so you know what you're dealing with.

I'll just quote some steps:

"Locate your Intake Air temp sensor"

"snip both wires cmoing out of the back of the IAT plug"


damn it, this shit is long. Well I hope you get the idea, it messes with the temp and your fuel system. U gotta snip a few cables, but they give you detailed instructions. I couldn't tell you if it works. OH yeah, and mine is called "G-Box Stage 1"

O.K. I'll help you out. I actually bought one of these Vortec mods from this ebay seller. Basically, all you will be getting is a single resistor, two wires (a red one, and a black one), and an ABS plastic box which encloses (hides) the cheap resistor that they've hastilly soldered in there. Oh yeah, you'll also be getting a "Vortec" sticker which is stuck onto the ABS plastic box to again "hide" the single screw that holds the two halves of the "module" together.

You can find out more on how this "mod" works by going here:

You could get all the parts at Radio Shack for less than $5 (I know, I saw the exact same ABS plastic box there, it's called a small project enclosure). The only thing is knowing what value resistor to use for your application.

All this "mod" does is trick your ECU into thinking that the intake air going to your engine is colder than it really is. Cold air is denser than hot air, so the ECU will advance the engine timing and give the engine more fuel (richer mix) to take advantage of the "extra" air your engine is supposedly getting. What you get is slightly more power and torque, but you'll be burning slightly more gas too.

Oh yeah, the resistor that came in mine was totally wrong for my application. The car ran like cr@p after installing it, I had to go down to Radio Shack and get a much higher value resistor. Now the car runs fine with a little bit of extra power, and the decrease in gass mileage is so that I can live with it.

If you have a multimeter, or ohm-meter, you can actually measure the resistance across your IAT sensor terminals (usually in the 1000 to 5000 ohm range). Mine was 3.77 kohms (3770 ohms). From there, you can try and calculate what resistor to use.

I actually did something like that to my friends ZX2... I didn't know what I was doing for him, but he said it was supposed to make the ECU think the engine was still cold and run a richer mixture, or something like that... and I'm just thinking to myself "Ok... so you're car will be running rich... that's not exactly the best thing in the world to have as a mod" :screwy:

exactly! alls it is is a couple wires attached to your ecu to make you run richer and not be able to pass emmisions! worthless scam

rich = less horsepower.

lean = more horsepower.. to a certain extent. you really want to run the car as lean as possible without it detonating.

heres what the description should say:

"install this worthless mod and use our sticker so everyone will know what a sucker you are! More fuel = more black smoke = worse fuel mileage! -20hp!"

:rolleyes:

The item is junk if you want extra ponies you can get a ECU on ebay for $20 + shipping and you will get 5hp or if your car has some big MODS you can get up to 10hp they however claim 5-20hp from a chip that is also B.S i have ran many different maps on a dyno. The best one so far was the Mugen chip. I have made some of my own programs and burned them to a chip but they are still in the testing phase. I'm working on one to help JDM motors pass smog :) Then you can swap it back to the performance MAP.

Peace Bro

Or, another way of doing that, is drill a teeny little hole in your manifold, right above the 02 sensor. Does the same thing, sucks in fresh air, tricks the ecu into thinking your running lean, pumps up the fuel. :banghead:

(thats what some hardcore ricer told me here)

yeah those little performance mods are crap they give u no power at all. my friend had on of those and we tested it and gave no hp gain what so ever but its ur money i say HELL NO not worth it

thats one of the gayest things ive ever heard of in my life

old thread, close it please.

b/f you close... I just want to say[QUOTE]rich = less horsepower.

lean = more horsepower.. to a certain extent. you really want to run the car as lean as possible without it detonating.

this is TRUE...

AND... I know it's a big word, but we all must learn it... STOICHIOMETRIC... the price of ignorance is astounding

its simple, you dont get major horsepower gains by going the cheap way , do u see skylines etc fitting these???? save and get a ecu chip or new ecu

hahaha... well said, jim :werd:

I've purchased one of them little mods,I put it in,it only made a difference of making my air/fuel ratio gauge to lean on the green side(rich),
still no difference.......
I'm better off getting more horsepower from a cardboard spoiler

Die thread die.
