i was just wondering if anyone ever put on one of those chips that supposedly add 20+ horsepower that are CHEAPly sold on ebay. i see they just attach to a sensor, but i was wondering if anyone could tell me if it was a worthwhile purchase or some stupid piece. thanks
horsepower - 6G Celicas Forums
man i wouldn't trust those, there what .99 cents! i doubt it does anything.
i guess all it does is make the ecu think its getting more air thus giving more fuel. but sounds like bull**** to me. i wouldnt trust it either.

i bet it adds 25-50 hp
ditto

tricks the ECU, yeah
Does it add HP? yup. Is it safe? nope. Can/Will either harm the engine, or the ECU

Ha maybe i should try it out when im ready to pull out my engine .. or if someone is getting ready to swap.. try it out..
It works!But it is a easy way to pop your engine on a hot day.It tells your computer that its getting cooler air then it advances your timing 2 degrees and then pop there goes your motor.Its a fifty cent resistor.your motor $800-$1500.Watching someones car blow up from a fifty cent chip=PRICELESS

To end the debate...
The resistor tricks the ECU into running the car at Open Loop all the time, which the ECU runs a fixed air/fuel map that is a lot more rich than normal. That does NOT add power. Running at open loop is designed to improve cold start and other situations where the engine may struggle for a bit more fuel. That's all it does... does NOT add power... etc. Doesn't do anything to timing, and even if it does (some cars may, depending on ignition set-up)... it'll be very very slight which will most likely be because of the knock sensor or something else.
End of these useless guesses...
