Is this dumb

I was kind of intrested and I wanted to know if its a good idea to buy it.

What do you think?

[whoguy]

That looks pretty dumb..... prob a resistor shunt across o2 sensor to cause always rich condition giving noticable increase in power at cost of life of engine.... wot u think?

[KSIbucky]

I really doubt because installation looks hard

[johnnyfive]

this is just like the juice box type mods....will trick the engine into running rich...

[spkrman]

bunch of BS...

it has been tested, yields a small gain straight off, but the ECU figures out whats goin on and takes it back to stock.

Forget it!

Try stay away from little HP cheap mods....

the only cheap legit mod would be the grounding kit. If you buy the specific grounding kit for the yaris, there will be HP gain. Ive read it in some car magazines....

And you actually feel it!

NO! You will get a nominal hp increase when making consecutive dyno pulls, until the car is at optimal temperature. That is all those "magazine" articles are showing. Those grounding kits only remove weight from your wallet and add it to your car.

The richer your car runs the less power it makes.
In order to make power you need a LEANER fuel/air mixture, but too lean causes detonation, pre-ignition and overheating.
Regardless what you add to your car to change the F/A ratio the ECU will compensate to maintain the perfect SAFE f/a mixture (stoich)

True!
But consider the benefit of having a reinforced ground throughout the vehicle; it's very important for those who have lots of electronics and ICE.

Grounding kits are good for reinforcing the ground connection, that's it.
They won't increase HP or performance significantly, if at all.

It's similar to saying a capacitor will allow your sound system to hit harder and your mains will be clearer, that's complete :bs:

Correcto!
