performance chips

[cbutler]

I was looking on ebay today and seen a number of very inexpensive (~$30) performance chips that basically consist of a simple resistor that connect directly to the stock ECU with no soldering or anything. These manufacturers are claiming horsepower gains of up to 30 horse power. They also claim that there is no risk of engine damage, and the chips will work with most modifications.
To me, this sounds too good to be true. Can anyone give me some insight and maybe recommend a good chip if indeed there is such thing as an effective low cost easy installation performance chip. Thanks.

I hope you're not serious man. You have a 1j or Supra for that matter and think one of these ebay POS's are worth it. Hell, I may be wrong but why would you put something on your car when you dont even know what it does? I didnt read about all of them but the one i saw didnt even say what it did. And since a motor is essentially a large air pump and this is strictly electronic I would assume its screwing with either timing or fuel (or doing nothing) and either way....nevermind. Try it out and let us know how it works! :nono:

good move dude... I made mad power with that chip.

 

[Figit090]

anybody else?? I'd like to know if they work....

Messing with a diesel's electronics sure as hell works...so i assume some things could be done.

IMO - although i dont know any of this for sure - it probably just messes with the EFI to give it more fuel and changes the timing...you will probably loose mpg and reliability. I would hope that whatever it is you could at least unplug it if it screwed up.

but i would like to know results...aside from one rather vague reply....

if it worked so well,would it sell for 30 bones? NO

These will not work on a Supra.

A little bit of history for you. In some cars - mostly domestics - there is an air temperature sensor that the ECU uses as one of the inputs to figure out how much air was going into the engine. If you hardwired this sensor, it was possible to get some extra power out of the engine, with the risk that you were running outside of the original engineering for the car.

On our Supras, we use two things to determine how much air is going into the engine - air speed, given by the AFM, and ambient pressure, given by a pressure sensor. Notice there is no air temperature... and therefore, nothing to hardwire to fool the ECU into thinking the intake temps are different from what they are.

That's the bad news.

The good news is that there are plenty of things you can do to make cheap power on a Supra. The even better news is that all of these are very well documented in our Reference section, which really should be a MUST read for anyone thinking of pushing more power through their engine anyhow.

Finally an informed and relevant reply to answer my question. Thanks.

OK didnt mean to be rude in my first post (bad hair day), but I did give you some relevant information as to why not to use this chip. I stated it is playing with either fuel or timing or nothing and with no way to monitor A/F or knock its not very safe to test it out, especially if it was claiming up to 30 hp there must be big changes in the timing or fuel. Figit, I believe you were referring to products such as Bully dog, which I'm sure has tons of R&D behind it and also adding fuel can help in some cases (mostly torque dept. like diesels) but anyone who has seen a stock ECU's A/F ratio on a 1j knows a lack of fuel is not a problem. Good info about how it actually does work but his car is not equipped with either an air temp sensor or AFM so I assumed its playing with something else and without any monitoring probly not too safe. And at 30 bux for an electronic device, I'm assuming theres not much R&D for it not to mention it claimed this product was for supras and solaras over like a 15 year span, ie. not specific. From experience generally if something sounds too good to be true it is, however im a born pessimist. (probly hard to tell)

lol....nope, not really. but i can be sometimes. thanks for the help everybody, my curiosity about that product is gone. :biglaugh:

Isnt it funny that you can increase your fuel economy and power by adding a chip to a diesel?

Is a conspiracy - automobile companies produce vehicles with the worst possible mileage they can get away with to boost oil company revenue.
