those ebay performance thingys (WITH PICS NOW)

i bought one of those 30 dollar chips thinking what the heck its only 30 bucks, just to see if it works, and it really actually does. the only prob is that the hold button flashes and a different orange idiot light comes on. i guess i can try test n tune again thursday night to see "for sure" if it works since i couldnt break 19 this past thursday night. illl also see how ****ty the gas mileage im gonna get is :shock:

you dont have to have any tools except a wrench to take off the negative battery cable while you do it. you dont cut or strip any wires the blue things you see are connectors that dont cut any wires so it can be taken off and put on easily.

AND ITS NOT ONE OF THE RESISTORS. THIS SPLICES INTO THE SENSOR WIRES RIGHT NEXT TO WHERE THE STOCK AIR FILTER WOULD BE.

whats it do?

it remaps the air/fuel ratio. i wouldnt put it in an everday driver b/c i lost my fourth gear somehow and dont like running 70 miles an hour at 4k rpm :shock: , but i would definitely reccomend it for track use, but in an automatic you wont hit 4th anyways in a 1/4 mile run.

i can definitely tell a difference in acceleration, there is no doubt about it.

i mean im no rocket scientist but i bet it would shave a second mabye a little more off of a 1/4 mile time, we'll see for sure come thursday night.

you can put it in and take it off in about 10-15 minutes.

i also read all the feedback comments before i made the purchase and seeing that 3990 of 4000 were positive with actual results, and some owners even dyno proved it, i went ahead and spent the whopping 30 bucks.

post more info, a link to the ebay page and maybe a pic if you could

+1 it sounds like this actually is worth the 30 bucks.

Bah im still skeptical tho, never trusted those ebay performance "chip" or enhancers whatever you want to call em, bought one a couple years back and was a complete waste of money.

Let's see what yours can do BigNasty, i am curious

im going to test n tune thursday night then i can give you a solid result

oh yeah i almost forgot, i did get my car to 115 today on I-40 in third and i ran aout of room, now remember it is an automatic

HERE IS THE LINK

Sorry to burst your bubble but that is a resistor inside a plastic box, you can reproduce it for like 90 cents at your local electronics store

but how can a resistor improve performance? i can definitely tell a difference in performance

That resistor "fools" your ECU to make it think that the outside air temp is much colder then it actually is, the ECU compensates by slightly increasing fuel to the engine. Colder air has more oxygen in it so the engine needs slightly more fuel to run properly. That's why cars are a bit harder on fuel in winter.

ok i see what your sayin now...

so does this thing pose any risk except the fact that my car doesnt have but three gears when its in and some idiot lights come on?

i mean if it works then it works i still wanna see how much of difference it will make on the 1/4 mile anyways

When i put mine in, i didnt really notice a difference, no lights came on either (wasn't the same one as your tho) but see if it makes a difference anyways, got nothing to lose, and it wont damage your engine.

i dont see how a resistor could make my transmission only use 3 of the 4 gears though. it seems to pull harder on the top end and slightly faster on the bottom end.

i know for sure though for 5 minutes after i installed it, the car ran like ****, like it felt bogged down almost, and then all of a sudden i heard a click and i could tell a difference at that point and now it seems better than before.

Maybe because it thinkls the air is cooler, it keeps the choke open and you have an auto trans it doesn't shift because it thinks the motor is cold?

Yea, 4th (or overdrive whatever you wanna call it) doesnt come on when the engine is cold or when its extremely cold outside, maybe this is why you only stay in 3rd

Choke on a FI vehicle LOL LOL LOL. Man what a sucker for buying a $30 resistor. people will never learn, oh yeah make sure you get a back O2 sensor for when you burn out yours out, also another set of spark plugs for when you get all that carbon build up on them and they foul out.

um....choke? LOL, fuel injection dude :lol: :laughing3:

who ever said that i was running this resistor on the IAT everyday anyways?, hell, if it gives me a half second or second better time at the track then ill use it there, i dont see much harm that could be done from occasional runs down a 1/4 mile.

& ok im out thirty bucks, which i probably would have pissed away anyways on some other stupid **** i didnt need like most people probably do

OK OK OK, it doesn't litterally have a choke..my bad

but this resistor is fooling the engine to think it's cold, that was my point

yeah the resistor part is true, its a box for a reason....theres no magical chip in it, probably a resistor with wire and some electrical tape inside of it, either that or its a circuit board with one resistor on it so it looks like they knew what they were doing.

if it doesnt help at all on my 1/4 mile time ill bash it with a hammer and tell you whats inside, ill even post pics lol :twisted:

Nice lol thats what i did with mine after 4-5 months of using it, piece of crap lol

i cant use my consistently anyways b/c driving the interstate at the speedlimit gives me about 15-17mpg mabye and dont like running 4-6k rpm in third for long periods of time lol

this might be good tho if you have a manual trans.

it works well for me in my automatic i have nice proven results on it on the 1/4 mile, just the loss of third gear means i only run it when im planning on racing

yeh and thats good, the fact that its only a resistor and its a cheap mod makes it better. but im sayin that with a manual you cant loose a gear cus your in control so it would be a definite plus that way. i dont have an auto but isnt there still a way to put it in the gear you want? i might just build my own resistor box and put it in. we'll see.

yeah i think i put that on another post that it would probably yield better results with a manual

hhhmmm im still fairly new to this forum, havent been able to read all the threads yet. but you can trulysay with confidence that it works.

Dont waste your money on those things man like i said you can reproduce these for 90 cents, why pay 40-50 buks, i tried it and i know, i even bought more then 1 cuz i tried one on my 1st car.

They dont work, they will only make your car guzzle more gas, your wayyyyy better off to get the intake redone for 50 buks then spend it on a resistor.

ive already done the cold air intake but ill even re-test at the track and post time slips with and without the resistor if you want on paper proven results that it helps. or i might can do a video b/c without the resistor i cant chirp tires and the car is a dog, but with it i can chirp them into second, and remember i have an automatic

anyone car to make a how to on this?

Here's a how to:
don't install it cuz it's basically useless.

I know that this is kicking a dead horse but do you realize more fuel without the actual colder air is going to hurt performance. You want the a/f ratio to be as lean as possible without detonating.

Not so true. If you go by that method, a simple change in humidity, elevation, or timing change could push you into detonation territory. A perfect A/F is 14.7 Anything less then 13 is dangerously rich and anything over 16 is dangerously lean. Being either rich or lean, to a point, will produce cooler temps and more power. Yes more/cooler air + more fuel = more power, but you still have to maintain a proper a/f ratio or you'll be doing more damage then good. Now since the Aveo runs naturally lean, these ebay thingys might actually do something

Ok so im an experimenter as some of you may know. i went to radio shack today and bought some resistors cus along with my new IAT harness cus my old one broke. i placed a resistor in line on each wire and connected it to teh intake. i used my obdII scanner to get some readings and my intake temp before the install was 122 degrees fair. (i installed the harness first w/out the resistors to get the reading.). my intake temp went from 122 degrees fair. to -38 degrees fair. YES! YOU READ CORRECTLY, -38! and my car was a bit spunkier and actually chirped both tires into second quite nicely. so... That was my experiment for you guys, and i got you the hard truth. oh and i used 22,000 ohm resistors.

The only thing it will do is take away H/P. Yes a perfect a/f ratio is 14.7, but that is only when not at WOT (wide open throttle). Hook up a wideband and see for yourself. No car will be at 14.7 during WOT because that is just going to detonate. 13 is not dangerously rich because my car consistantly dips into the 10s.
You want the car as lean as possible without detonation to make the most power. adding more fuel without more air is going to make the a/f ratio richer and make you lose hp.

um i guess all im gonna say is that i wont dispute the data i got and/or the results. i will be able to give more info tomorrow once ive had the car up on the hwy.
