Sorry I don't know how to do links. Basically, all it is is a "speed" chip that acts as a "piggy back" to the ECU that increases the fuel injection to the motor and supposively is dyno proven to increase hp by 15-20. Lemme know what you guys think and if you can get to the link or not. Thanks guys.

im sure it would work, hp numbers i dont think would be that high thou. as long as they make those right. from what im getting from the ad, it changes the output resistance of the MAF(very easy to do, which = cheap)to say its reading different temperature air, making it either advance the timing/fuel or lean the motor out a little for a better combustion, not sure exactly what that would do. its possible to burn a motor up(over lean) or cause pinging/detonation(advance timing too much) that way tho.

i dont know if i really feel like blowing my engine up lol... or detonating it with a $10 piece of electronic.

Anything that changes info to the computer aside from actual conditions is not good. A cold air intake actually cools the air so not a big deal but telling the computer it is different then actual? Not good. Any item on ebay you ever see that brags about hp for $1/1hp ratio probably isn't worth it. Also, if you read feedback on these type of items, many say that it wasn't worth it. Don't you think that for $10 everyone here and in every other automotive forum would have them and brag about them?

it will lean out your a/f ratios which will give you more power and less fuel consumption, but in the end you might melt your pistons if it leans it out by too much.
better stay away from it
there are heaps of other mods which can be done under 20$

i never suggested using it haa, just said it would probably work. i posted my warnings at the end too.

What kind of mods, Strannik? I am currently working on getting my 87t in mint condition, and then I plan on modding it a bit. It has 255k on it, but the engine was rebuilt ~35k miles ago.This is my first car and I use it as a daily driver, so any cheap and easy to install mods are great.

Any help is appreciated

It doesn't lean it out; colder air means denser air means ecu dumps in more fuel to maintain stoich. Colder air readings without colder air means ecu dumps in more fuel than stock fuel map allows = rich mixture

soo, is that good or bad

which means waste of fuel and stuffed cat and absolutely no power gains
you can just disconnect the temperature sensor used for warm up and run permanently rich

i think those boxes make ecu think it actually gets less air then it does - thats the only way i can see the car would be making more power
mk3's run rich from factory already, no point making it even more rich

regarding under 20$ mods, there is a whole thread of them listed on supraforums.com, just look over there see if anything suits you
