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

this is the potenciometer trick it has to be a 10k potenciometer this is the hot shit right now with the yaris in pr. what this does is that it tricks the computer that the engine is -10 colder and it sends more fuel and it revs up preety fast and sucks more air for those of us who have cold air intake its a noticeable gain. don't have to run dynos cuz you can feel it...BUT you only turn it on while racing because if you leave it on it keeps sending fuel and when youre in a stop the car shuts down cuz it floods with fuel. think of it as a manual fuel regulator/faster rever/air suker thingy

first of unplug this sensor

then cut the red wire and put two wires to conenct the potenciometer then connect it back on

pass the wires inside the car and connect to the potenciometer

when you turn the car on it turns on like nothing happened. turn the potenciometer on ''clockwise'' till the end and the car revs up and the cool in the dash shows. thats how you know its put on correctly enjoy!!


anothe of my mods:
the famous 3' pbc CAI
top:

bottom: i put in the tip a little screen to keep out leaves and stuff when it rains i disconect it from the top and no problem

took these air hoses off so the engine can breathe better you can feel the difference and it sounds alot better

the header:

2 1/4 straight pipe from the header to the muffler and in the middle a cut out the cut out gives you like 9whp more so its a very good gain

and here's my baby. i still haven't finished the outside or the engine upgrades. i'm going 4 the black red theme for it
i hate it when they construct in the hood gets ma' ride dirty

gotta put some rims but gotta work with what i have... still... for hubcaps they look hottt lol

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

right.... so when your car catches fire can you post a DIY on fire suppression on the Yaris?

btw it's spelled potentiometer in english.
