HOW TO PUT THE 10K POTENCIOMETER AND A COUPLE OF MY MODS

[YarisSedan]

This is really dangeriouse. Google open loop and closed loop. You are forcing your vehicle into open loop so it is not in control of the fuel trim. Driving your car hard like this can cause damage to things. In open loop the computer disreguards o2 sensor readings and bases mostly on preset conditions to get the car to warm up as quickly as possible.

So basically you are wasting a extreme amount of gas causing catalitic converter damage due to running excessively rich. Fouling your spark plugs, excellerating carbon buildup on top of the pistons and valves which in turn will eventually cause you to loose more gas milage and power. So all in all a stupid mod. Not to mention this will void your warrenty.

Also by eliminating your PCV system ie positive crankcase ventilation. What do you think will happen to all that pressure. The most common cause of oil leaks in cars today is one either someone overfilled the engine with oil or 2 the PCV valve is clogged or stuck shut. Causing pressure buildup till it blows a seal usually the valve cover gasket or oil pan gasket will start to leak as a result. So by doing that you are causing yourself more problems. So by removing the pcv system i still dont understand how you think it will help your engine breath better??????

Not to bash you but it seems like you dont have a understanding of how vehicles work and function and what devices you are eliminating or trying to modify will have an effect on your car.

first of i don't have a cat its straight to the back so no damage there
second im not so stupid to overflow my engine with oil
it breathes better cuz there are no stupid factory hoses interrupting the air flow
third if you wanna race with good cars fuck the warranty this sport is not cheap. if i blow a gasket trying to race a nigga ill blow 100'
when the potenciometer is on the computer reads the engine -10 and when is off its normal the engine is not hotter i cheked it myself with a obd2 reader if u guys are scared or doing it well i'm not
