Term

tuning software

"How to use what is commonly thought of as a tuning software and breaking the law. How to actually use it for good for students."

Tuning software is a special computer program that lets you change how a car's engine works to make it run better or faster.

timing

"So when the vehicle's cold, it looks at this and it says, yeah, add this much timing or if it's got flex fuel, it does this."

Timing is when the spark happens inside the engine to make the car run. Changing it helps the car run better when it's cold or warm.

Term

flex fuel

"or if it's got flex fuel, it does this. So they can see those things,"

Flex fuel means a car can use different types of gas, like regular gas or a mix with alcohol. The car knows what fuel it's using and changes how it runs to work best.

Part

ignition coil

""oh yeah, you got to put a bigger ignition coil in this distributor on this Honda.""

The ignition coil helps make the spark that starts the car's engine. It changes the battery power to a stronger spark that lights the fuel.

Part

distributor

""oh yeah, you got to put a bigger ignition coil in this distributor on this Honda.""

The distributor helps send the spark to the right part of the engine so it can start and run properly.

Part

spark plug wires

""Well, it's just that I didn't put the spark plug wires back on in the correct orientation.""

Spark plug wires are like special cables that carry electricity to the engine parts that make the spark to start the car.

Term

brake job

""I can make so much more money doing a break job or struts or an alignment or an engine or a head gasket or a misfire or whatever it is.""

A brake job means fixing or changing parts of the car that help it stop, like the brake pads or discs, so the car can stop safely.

Term

struts

""I can make so much more money doing a break job or struts or an alignment or an engine or a head gasket or a misfire or whatever it is.""

Struts are parts of a car that help make the ride smooth by absorbing bumps and holding up the car's weight.

Term

alignment

""I can make so much more money doing a break job or struts or an alignment or an engine or a head gasket or a misfire or whatever it is.""

Alignment means adjusting the car's wheels so they point the right way, helping the car drive straight and the tires last longer.

Term

head gasket

""I can make so much more money doing a break job or struts or an alignment or an engine or a head gasket or a misfire or whatever it is.""

A head gasket is a part inside the engine that seals important areas so oil and water don’t mix. If it breaks, the engine can get damaged.

Term

misfire

""I can make so much more money doing a break job or struts or an alignment or an engine or a head gasket or a misfire or whatever it is.""

A misfire is when the engine doesn’t fire correctly in one part, making the car run rough or lose power.

Part

MAP sensor

""Everyone thinks it's speed density because it's got a map sensor, not a mass airflow sensor...""

A MAP sensor is a part that tells the car how much air pressure is inside the engine's air intake. This helps the car know how much fuel to use.

Part

mass airflow sensor

""Everyone thinks it's speed density because it's got a map sensor, not a mass airflow sensor...""

A mass airflow sensor is a part that measures how much air is coming into the engine. This helps the car add the right amount of fuel.

Term

wide open throttle

"why when it goes wide open throttle, when the car goes wide open throttle, it goes back into open loop instead of closed loop. ... It spikes rich when it goes wide open throttle."

Wide open throttle means you press the gas pedal all the way down so the engine gets as much air and fuel as possible to go fast.

Car

Chevrolet Cavalier

"and they beat the tarnation out of this poor Cavalier. It's old, I should probably get rid of it. It's like a 2005 Cavalier, but it won't die."

The Chevrolet Cavalier is a small car made by Chevrolet. The 2005 version is an older car but still works well for learning and testing.

Car

Pontiac Solstice

Concept

E85

""Even, you know, E85 in a vehicle. I, this poor Cavalier, it's not a flex fuel-based vehicle. And as it's running, we're looking at the fuel trims in the graph... I just straight dump some E85 in it while it's running. And they watch the fuel change, change, change, change, change.""

E85 is a type of gas that has a lot of alcohol mixed in. Some cars can use it to run better, but not all cars are made for it.

Term

fuel trims

""we're looking at the fuel trims in the graph. And it's, you know, it's running and it's got gas in it. And then it's sitting on the diners idling and they see the fuel trims zero to, you know, one, two, three.""

Fuel trims are the car's way of changing how much gas it uses to keep the engine running smoothly.

Term

oxygen sensors

"But they see that oxygen sensors start to like sneak up just images of the pegs lean."

Oxygen sensors are little devices in the car that check how much oxygen is in the exhaust. This helps the car know if it needs more or less fuel to run well.

Term

"I was just had a conversation with somebody last night with the power of RC cars and we were talking through like, I actually was one of my coworkers here at Wrenchway that he has RC cars at home and he's like, I got the electric ones now, but he said, I missed the nostalgia of trying to get the old engine to start and having it not start and having to figure it out."

RC cars are small cars you can control from a distance with a remote. Some run on batteries, and others have tiny engines that need fixing and tuning, which helps people learn about cars.

Car
