Increase HPs chips Options

[satelite]

I wanna know about some expiriences in the use of speed chips in Celica 6 gen. Is true the increse in 35 hps?

It is not a chip.
It is just a $0.25 resistor you can get from any Radio Shack.
It is hooked to the air intake temp sensor in serial.
The purpose is to increase the resistance of the air temp sensor and fools the ECU to think that colder air is entering the engine and advance the timing.
(the colder air it is, the higher the resistance the temp sensor will give out)
What really happens is the actual temp of air entering the cylinders is still high.
And the ECU does not rely on the temp sensor alone.
Once it detects more knock and other inconsistency of feedback from other sensors, it will figure out and pull the timing back.

In short: useless
