"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.
Tuning software refers to computer programs used to modify a vehicle's engine control unit (ECU) settings. This software allows adjustments to parameters such as fuel maps, ignition timing, and boost levels to optimize performance or efficiency.
"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.
Timing in an engine refers to the precise control of when the spark plug ignites the air-fuel mixture in the combustion chamber. Adjusting timing can improve engine performance and efficiency, especially under different conditions like a cold start.
"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.
Flex fuel refers to a type of fuel system or vehicle that can run on more than one type of fuel, typically gasoline blended with ethanol up to 85%. The vehicle's engine control unit adjusts timing and fuel delivery based on the detected fuel mixture.
"It's 400 bucks for some sort of scanning diagnostic tablet device. You can't beat the cost of something like that."
A diagnostic tablet is like a special computer that helps mechanics find out what's wrong with a car by reading its computer.
A diagnostic tablet device is a portable tool used by mechanics to scan a vehicle's computer systems for fault codes, sensor data, and other information. These devices help identify issues and perform adjustments or resets.
"And back then, we were taking the EEPROM and making an electronically erasable EEPROM and soldering into the board on a P28 module on those."
EEPROM is a special computer chip in a car that controls how the engine works. People can change it to make the car run better or faster.
EEPROM stands for Electrically Erasable Programmable Read-Only Memory, a type of memory chip used in car engine control units (ECUs) to store data like fuel maps and ignition timing, which can be modified for tuning.
"I had a lot of people that like general motors products. So I was like, okay, I can figure out what the tuning software is for that."
General Motors is a big car company that makes many different kinds of cars and trucks you might see on the road.
General Motors (GM) is a major American automotive manufacturer known for brands like Chevrolet, GMC, Cadillac, and Buick. It produces a wide range of vehicles from trucks to passenger cars.
"Because even today, I still have a chassis dyno at my own shop. It's just like my hobby shop, just to be clear."
A chassis dyno is a machine that lets you test how strong and fast a car is by running it while it stays in one place.
A chassis dynamometer (chassis dyno) is a device that measures a vehicle's power output and performance by simulating road conditions while the vehicle remains stationary. It is used for tuning, diagnostics, and performance testing.

""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.
An ignition coil is an electrical component in a car's ignition system that transforms the battery's low voltage to the high voltage needed to create a spark in the spark plugs, igniting the fuel-air mixture in the engine.
""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.
A distributor is a component in older ignition systems that routes high voltage from the ignition coil to the correct spark plug at the right time to ignite the engine's cylinders.
""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.
Spark plug wires carry the high voltage from the distributor or ignition coil to the spark plugs, which ignite the fuel-air mixture in the engine cylinders.
""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.
A brake job is a maintenance service that involves inspecting, repairing, or replacing brake components such as pads, rotors, and calipers to ensure the vehicle's braking system functions safely and effectively.
""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.
Struts are a key part of a vehicle's suspension system that combine a shock absorber and a coil spring into a single unit. They help absorb road impacts and support the vehicle's weight, contributing to ride comfort and handling.
""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.
Alignment refers to adjusting the angles of the wheels so they are set to the car manufacturer's specifications. Proper alignment ensures even tire wear, good handling, and safe driving.
""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.
The head gasket is a seal between the engine block and cylinder head that prevents coolant and engine oil from mixing and maintains compression in the engine cylinders. A blown head gasket can cause engine overheating and serious damage.
""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.
A misfire occurs when one or more engine cylinders fail to combust fuel properly, causing rough running, loss of power, and increased emissions. It can be caused by ignition, fuel, or mechanical issues.
""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.
A MAP (Manifold Absolute Pressure) sensor measures the pressure inside the intake manifold of an engine. This data helps the engine control unit calculate the amount of air entering the engine for proper fuel delivery, especially in speed density systems.
""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.
A mass airflow sensor measures the actual amount of air entering the engine. This direct measurement helps the engine control unit adjust fuel delivery accurately, commonly used in mass airflow-based fuel systems.
"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.
Wide open throttle (WOT) refers to the condition when the throttle valve is fully open, allowing maximum air into the engine for maximum power output. During WOT, the engine often runs in open loop mode.
"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.
The Chevrolet Cavalier is a compact car produced by Chevrolet, with the 2005 model being among the last before the model was discontinued. It is often used as an affordable, durable vehicle for educational and testing purposes.
"And then we put a Pontiac Solstice on that has, it's a turbocharged vehicle, wide band equipped in it."
The Pontiac Solstice is a small sports car made by Pontiac. Some versions have a turbocharger which helps the car go faster.
The Pontiac Solstice is a two-seat sports car produced by Pontiac from 2006 to 2009. It is known for its sporty handling and was available with a turbocharged engine option.
"that has, it's a turbocharged vehicle, wide band equipped in it."
A wide band sensor helps the car's computer know exactly how much fuel and air are mixed in the engine, which helps it run better, especially in cars with turbochargers.
A wide band oxygen sensor measures the air-fuel ratio over a wide range, providing more precise data than narrow band sensors. This is especially useful for tuning turbocharged engines.
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.
E85 is a fuel blend consisting of 85% ethanol and 15% gasoline. It is used in flex-fuel vehicles designed to run on varying ethanol blends, offering higher octane and cleaner burning but requiring specific engine calibrations.
""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.
Fuel trims are adjustments made by the engine control unit (ECU) to the amount of fuel injected into the engine to maintain the ideal air-fuel ratio for efficient combustion and emissions control.
"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.
Oxygen sensors measure the amount of oxygen in the exhaust gases to help the engine control unit adjust the air-fuel mixture for optimal combustion. They play a critical role in emissions control and engine efficiency.
"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.
RC cars are remote-controlled miniature vehicles often used as toys or hobbyist models. They can be powered by electric motors or small internal combustion engines, the latter requiring tuning and mechanical knowledge.
"... got a Malibu. Like, Oh, you do? Yeah, I got a 96 Civic. What's up? You ain't got one of those. I do. Wa..."
The Honda Civic is a small car made by Honda. It's popular because it uses little gas and is easy to take care of. The 1996 model is an older version that many people still like for everyday driving.

It's tough in the shop.
Every man for himself.
That's not true.
There is teams everywhere.
People do help each other out.
Good people help each other out.
Because good people can see that
when me and you do something together,
we're two and a half times successful
instead of two times successful.
Welcome back to Beyond the Wrench.
My name is Jay Gannon and I am your host.
Today we're joined by Garrett Jacobson,
an automotive technology instructor
at Hawkeye Community College,
who's focused on preparing the next generation
of technicians for successful careers
in our industry.
In this episode,
we'll talk about Garrett's journey
into automotive education,
what he's seeing from students entering
the industry today,
and how educators and shop leaders
can work together to build
a stronger technician pipeline.
How are you?
Not too bad yourself?
I am doing good.
So I had the pleasure of meeting you
as we record this just about a week ago.
You and I were on a roundtable
at the Vision High Tech Conference in Kansas City.
And I have to start by saying,
your energy just captured me, right?
You brought this different level of energy.
I think the room really took note of that.
And you just have a presence about you
that was just amazing.
So I've been looking forward to this.
I think this is really, really cool
that we were able to get you to come on the show.
I appreciate it.
I'm glad that it's noted as a good thing.
Sometimes I get to hear that I have too much energy
or I'm too loud.
So matter of fact,
I think I was actually told
that I was too loud at Vision at one point too.
So you'll have that.
So I was on the other side
of the too loud conversation, right?
And it was, I believe,
you were going through and doing some software training
you were doing.
What were you teaching on in the other room?
Yeah, and HPTuners related stuff.
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.
Because this is engaging and it's really cool to them.
So to be able to use that software in your classroom
and also to really understand what a mass airflow table it
really is, they can see a picture of it
instead of seeing the sensor and the operation.
So like us as instructors,
how to use that for good, essentially?
I will admit, I was in the other session,
but because you were talking about HPTuner stuff
and that seemed maybe a little bit more intriguing
than the conversation I was a part of,
my ears were definitely drifting that way.
And I was wishing that I was in that class
because that sounded,
it sounded really, really cool.
And what an awesome tool to be able to appeal
to the younger generation,
to the car community in general,
HPTuner is a fantastic company, just really cool class.
It's always, I mean, here at the college,
it was a weird thing for some people to go,
oh, wow, you're using HPTuners with your students?
That doesn't seem right.
Like, oh, you must be deleting emissions.
And that is completely not even the narrative.
It's a great scanner, truly a great scanner.
It's on the students' laptop.
They download the software free.
We have the hardware.
So what better thing to use than that?
The logging of it is phenomenal.
They think it's cool just because it's fancy
and fuels tuning.
Even we're not even using the editor.
On my side of it, for my computerized controls classes
and stuff like that, I'll use it as far as,
I'll read a module and I'll show them,
hey, this is what a speed density table looks like.
Like, this is what's in the module, guys.
This is what a multiplier table looks like.
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.
So they can see those things,
but being able to, for us as instructors,
to throw it out to those students, they love that stuff.
And it's cheap too.
It's 400 bucks for some sort of scanning
diagnostic tablet device.
You can't beat the cost of something like that.
So that's why we have a bunch of them here in our shop.
I mean, the students love it.
They grab it.
Yeah, we got the top-downs and zoos and hotels
and all the OEM stuff, but it is a commonly sought out one.
They go grab it immediately.
How did you get into that part of the world, right?
Because I think it's so cool.
I do think, as cars continue to get more complex,
I think that's a really cool way to teach
different things that you're trying to land home
when it's one of those cool things
that maybe would appeal to a student.
But how did you get started in it
and kind of tinkering around with computers?
Because that's some pretty advanced stuff.
When I was 16, I had my first set of keys.
And of course, like every other young individual,
we try to make our stuff go faster.
And I like third disclosure.
I was that Honda guy that everyone hated,
like the loud Honda.
Yes, that was me.
You had the coffee can?
Oh, yeah, yeah.
And does my wife make fun of me for this?
Yes, but remind her that she's been with me now.
We've been together almost 20 years now,
so she's stuck with that guy.
But that was just my passion,
was trying to make cars fast.
And it blended into what I ended up doing in the field.
I went to school for this stuff
and doing engine-derivability diagnostics,
advanced electrical stuff.
But I had a Honda and I had to figure out
how to make this thing faster.
And back then, we were taking the EEPROM
and making an electronically erasable EEPROM
and soldering into the board on a P28 module on those.
And it kind of grew from there.
And the reason I did it, just like every other 16-year-old,
I didn't have a lot of money.
But I did have the internet.
And I could read things and I could figure things out.
This was like, while I did mess some things up on my own,
I figured things out in cheap ways to make stuff work.
And it grew from there.
Eventually, then it was like, okay,
I had a lot of people that like general motors products.
So I was like, okay, I can figure out
what the tuning software is for that.
And then that's where HP Tuners came in.
And it was like, okay, I can make some money doing this
on the side.
And so I was like, okay, I'll start tuning some vehicles
here and there.
And then it kind of exploded from there in a good way.
But I will honestly say that tuning
made me a better diagnostic technician.
Because even today, I still have a chassis dyno at my own shop.
It's just like my hobby shop, just to be clear.
It's not like it's a full-on thing or anything.
But I would say 80-plus percent of the vehicles that come to me
have a problem.
So I have to electronically or drivability diagnose
whatever the issue is, just to tune it.
And that's where it really makes great case studies
for students, because it's like cool.
It's like a cool car.
It's a Mustang or it's a Challenger or a Camaro or a G8
something, right?
But I was too cheap of a kid to pay somebody else to do it.
And I had the resource that everyone has, the internet.
And it's even more powerful now than it was then.
So we can get these things.
And I guess I had the drive to figure it out.
And it worked out.
And it's been fun.
It's just a different part of the world that I've been able
to dabble in.
And some of my students, a lot of students come,
and they don't come just because they're like,
yeah, I want to do work.
As an automotive instructor, they don't always like,
yeah, I want to go work on an independent or a dealership.
They came because they thought cars were cool.
And I was that person.
And I can see that.
And some of them do work.
We've had students leave here, Iowa,
go work down in Florida, or in Atlanta,
at different performance shops.
It's not uncommon.
Unfortunately, we got some of those connections now
to be able to do that stuff.
There's different avenues in the automotive world.
It's not just one avenue.
There's a lot of other things.
And being able to myself go that direction with it was fun.
And then be able to see students go that direction
was enticing fun to see everything happen with it, too.
Did you freak out at all when you were 16 years old,
