Seema

Seema is a company that runs a program called Seema Garage. They help people with things like meeting emissions rules and engineering/testing support.

Company

EPA

The EPA (U.S. Environmental Protection Agency) sets federal emissions rules and oversees compliance testing requirements. In this segment, it’s mentioned alongside California’s rules as part of the testing procedures members must handle.

Company

CARB

CARB (California Air Resources Board) is California’s regulator for air quality and vehicle emissions. The segment emphasizes that compliance testing may need to satisfy both EPA and CARB requirements.

Term

ADAS system

ADAS systems are driver-assistance technologies that use sensors and software to automate or support driving tasks (like lane-related functions and braking interventions). The segment connects ADAS to how vehicle changes can affect calibration and behavior.

Term

lane splitting

Lane splitting is a motorcycle practice where a rider moves between lanes of slower or stopped traffic. The segment raises it because ADAS systems may be calibrated to detect motorcyclists and can behave unpredictably when they see them.

Term

lane filtering

Lane filtering is closely related to lane splitting and generally refers to motorcycles moving through traffic gaps at low speed. The speaker notes the terminology and then ties it to how ADAS systems interpret motorcyclists.

Term

calibrations

Calibrations are the tuned settings for sensors and control logic in an ADAS-equipped vehicle. The segment says systems may be programmed to account for motorcyclists, but that can still lead to unpredictable responses.

Brand

Tesla

Tesla is referenced as an example of a vehicle with long-running autonomous/driver-assist features. The speaker uses it to illustrate how perception issues (like shadows) can trigger unexpected braking.

Term

false reaction

A false reaction is when an automated driving system responds as if it detected a hazard when it actually didn’t. The segment uses an example where a shadow triggers braking behavior, illustrating how perception errors can lead to sudden interventions.

Topic

SEMA garage

SEMA Garage is a SEMA program that helps aftermarket companies work with car manufacturers (OEMs) and deal with rules. The goal is to make it easier for aftermarket builders to get the info they need.

Term

OEM

OEMs are the companies that make the car in the first place. In this discussion, it means the “factory” side that aftermarket companies try to coordinate with.

Term

tech transfer

Tech Transfer is a shared SEMA system that stores digital design files. It lets aftermarket companies access those files so they can design parts that fit correctly.

Term

aftermarket manufacturers

An aftermarket manufacturer makes parts that aren’t from the car’s original maker. In this segment, they’re using shared CAD files to design new parts for specific vehicles.

Term

intake

An intake is the part that brings air into the engine. This segment is about designing an intake that fits the engine correctly using factory digital files.

Ford Mustang

The Ford Mustang is a popular American sports car with lots of aftermarket parts. Here it’s just the example of a car you could design a new intake for using factory digital files.

Term

reverse engineering

Reverse engineering means figuring out how something is made by studying it closely, often by measuring or scanning it. In this segment, it’s what you’d do if you didn’t have the factory digital files.

Term

0.0 file

A “0.0 file” is the perfect digital version of the part—like the blueprint with no errors. Using that reference helps make sure the real parts line up correctly.

Term

manufacturing tolerance

Manufacturing tolerance is how much a part is allowed to be slightly off from the perfect size. If several parts are each a little off, they can add up and cause things not to fit right.

Term

stacking those tolerances

Stacking tolerances is when small manufacturing variations in multiple parts accumulate together. The result can be a part that technically meets specs individually but still binds or doesn’t assemble correctly in the real world.

Topic

SEMA sphere

They’re talking about the SEMA community—where lots of aftermarket and specialty car companies connect. The “sphere” just means the broader industry around SEMA.

Term

solid shifter joint

It’s a stiffer part in the shifter linkage that makes the gear changes feel more precise. The tradeoff is that it can make the car feel noisier or more “vibraty” inside.

Term

NVH

NVH means noise, vibration, and harshness. If a part increases NVH, it usually makes the car feel louder or more vibrating than stock.

Term

Sport Activity Vehicle

An SUV is a taller, more spacious type of vehicle, often used for both daily driving and light off-road. The speaker is saying SUVs are doing especially well in sales and interest.

Term

sequential transmissions

A sequential transmission is a gearbox where you shift one gear at a time in order. It’s common in racing because it can make shifting quicker and more repeatable.

Brand

6XD

6XD is a company/brand that makes racing-style gearboxes. In this segment, they’re being praised as a top choice for serious builds that need a transmission that can handle hard use.

Term

emissions compliance

Emissions compliance is about following the rules for how much pollution a vehicle or emissions system is allowed to produce. It usually means keeping the equipment working correctly so it still meets the legal limits.

Term

California Air Resource Board

CARB is California’s agency that sets rules to control air pollution. For cars, it can mean stricter emissions requirements than the federal rules, so businesses may have to follow both.

Concept

Clean Air Act of 1991

The Clean Air Act is a big U.S. law that created the rules for controlling air pollution. The speaker is using it as background to explain how current emissions regulations came to be.

Company

Environmental Protection Agency

The Environmental Protection Agency (EPA) is the U.S. government agency that helps set and enforce rules to protect the environment. Here, it’s the federal body overseeing emissions rules.

Term

Air Resources Board

The Air Resource Board is California’s agency for air-quality rules. The episode compares it to the EPA to explain who controls emissions standards at the state vs federal level.

Term

grandfather California

“Grandfather California” means the federal government lets California keep its own emissions rules. It’s a way to allow state standards while still keeping federal control in place.

Term

California Executive Order

A California Executive Order is an official rule or directive from California. In this episode, it’s mentioned as part of the process for getting emissions-related products approved.

Term

emissions testing

Emissions testing is how regulators check whether a vehicle (or emissions-related product) meets pollution rules. The speaker is saying you need proof from testing to sell legally.

Brand

CEMA

CEMA is the group the speaker says created a program to help companies prove their products meet emissions rules. The goal is to avoid having to go through California’s process only.

Term

emissions device

Emissions devices are parts on a car that help reduce pollution from the exhaust. The speaker is saying the product must not interfere with those parts.

Term

National Vehicle Emissions Lab

The National Vehicle Emissions Lab is an EPA testing facility. The speaker is saying the EPA’s emissions experts reviewed their program.

Place

Ann Arbor

Ann Arbor is a city in Michigan. The host mentions it because the EPA has an emissions-testing lab there.

Place

Detroit

Detroit is a city in Michigan. The speaker says the EPA audited the program there, which implies an in-person review.

Term

California EO

In this context, “EO” is a California approval that says an aftermarket emissions-related product meets California’s rules. The discussion is about how people can get approval without relying only on California’s process.

Term

California still has authority

Even if a product is approved for most of the U.S., California can still require its own emissions approval. So you may still need California-specific paperwork to sell there.

Term

pass and a fail

In testing, “pass” means the product meets the emissions limits, and “fail” means it doesn’t. The host is saying CEMA’s rules are set up to match California’s limits.

Term

cover letter

A “cover letter” is being used as part of the documentation package to apply for a California Executive Order. The host claims that the CEMA certification report already contains the necessary test data, so the cover letter is the administrative step to submit it to CARB.

Term

make model year trim packages

This means the approval isn’t just for a car model name—it’s for specific versions of that car. The report lists which make, which model year, and which trim levels the product is approved for.

Volkswagen Eos
Car

Volkswagen Eos

The Volkswagen Eos is a car with a special roof that can open and close. The podcast mentions it in connection with emissions rules and approvals. That’s about whether certain emissions-related parts are allowed for that vehicle.

Term

fast track program

A “fast track program” is a quicker way to get approval. Instead of starting over, regulators can use what was already submitted, so the process takes less time.

Term

C-Migrage certification process

“C-Migrage” sounds like a specific approval workflow for aftermarket parts. The host says it’s designed to be faster, and it includes helping with the testing paperwork and getting the right vehicle for the process.

Term

test summary report

A test summary report is the official write-up of test results. In this program, engineers use it as the key document that supports certification.

Term

supercharger

A supercharger is a device that forces more air into the engine. More air can mean more power, but it usually requires tuning so everything runs correctly.

Term

engine management

Engine management is the car’s computer system that controls how the engine runs. If you change parts that affect airflow, the computer may need to adjust fuel and spark to match.

Term

fuel management

Fuel management is how the car decides how much fuel to inject and when. If you change airflow-related parts, the car has to adjust fuel so the engine burns correctly.

Term

spark

Spark is what ignites the fuel in the engine. If you change airflow or fueling, the timing of that ignition may need to change too.

Term

airbox

The airbox is part of the intake system that channels air into the engine. It’s part of the path the speaker says emissions rules cover when you modify intake-related components.

Term

emissions regulation

Emissions regulation is the law about how much pollution a car is allowed to produce. The speaker is saying certain modification areas are covered by those rules.

Term

dino time

“Dino time” means time on a dyno (a machine that measures engine output). It’s usually billed by the hour, along with extra costs like fuel used during testing.

Term

certified test fuel

Certified test fuel is a specific, standardized gasoline used for official testing. It’s expensive because it has to meet strict requirements so test results are fair and consistent.

Tesla Semi

The Tesla Semi is an electric truck used to move goods. Instead of using diesel fuel, it runs on electricity. It’s meant for long-distance hauling like other freight trucks.

Topic

SEMA show called FutureTech

FutureTech is a special section of the SEMA show that looks ahead at what car technology might look like years from now. Instead of just showing what’s new this year, it tries to predict what will change the industry later.

Term

software defined vehicles

A software defined vehicle is a car where software controls a lot of how it behaves. That can make it easier to update or “tune” the car’s settings without swapping as many physical parts.

Term

algorithm

In this context, an algorithm is the software logic that determines how a vehicle system responds. The speaker is contrasting older hardware-based tuning with newer software-based tuning where you can change the logic controlling behavior.

Term

brake modulation

Brake modulation is how the car manages braking force as you press the pedal. Tuning it can change how smooth or how “grabby” the brakes feel.

Term

chassis tuning

Chassis tuning is adjusting the vehicle’s handling characteristics by changing how the chassis systems work together. With software-defined vehicles, that can include control logic and calibration across multiple subsystems, not just springs and shocks.

Concept

California EV mandate program

The host is talking about California’s plan to push people toward electric cars and away from gas cars. The concern is that it could make it harder to buy non-electric vehicles in the future.

Concept

EV

EV means electric vehicle—cars that run on electricity instead of gasoline. The discussion is about rules that would push more sales toward EVs.

Concept

internal combustion engines

An internal combustion engine is the classic gas or diesel engine that powers most cars today. The conversation is saying the mandate would eventually ban new gas-engine vehicles.

Concept

California's emission standards

These are California’s rules for how much pollution cars are allowed to produce. The segment says other states may copy those rules, which can spread the impact beyond California.

Concept

congressional review act

This is a federal process where Congress can step in and overturn certain government rules. Here, it’s mentioned as the mechanism that helped stop California from enforcing its EV mandate.

Term

transmission interfaces

This is a device that helps a new engine computer “talk to” the car’s transmission. It lets you use aftermarket tuning without the car fighting the factory transmission controls.

Term

standalone ECU

A standalone ECU is an aftermarket computer that controls the engine. It gives you more tuning options than the factory computer, especially for modified builds.

Term

OE setup

OE setup is the factory setup your car came with. The host is saying you can replace that factory electronics arrangement with aftermarket parts.

Term

plug and play solutions

Plug-and-play means the parts are made to connect easily to your car. It’s usually quicker to install and less likely to require cutting or custom wiring.

Topic

SEMA membership

They’re talking about how joining SEMA (the trade group for the specialty-equipment market) helps the organization speak louder. More members means more influence when dealing with rules and regulations.

Term

8S calibration numbers

These “calibration numbers” are settings inside the car’s computers. If you change the truck with mods, you may need the right settings so the car still behaves correctly.

Term

lift kit

A lift kit raises the truck higher off the ground. That can change how the car’s sensors and systems work, so sometimes you need adjustments after installing one.

Chevrolet C8
Car

Chevrolet C8

The Chevrolet Corvette is a sports car built for fast driving. The TCU is a computer that helps control the automatic transmission. When people talk about getting access to it, they mean they can better understand or adjust how the car shifts.

Term

TCU

TCU means the car’s transmission computer. It decides when and how the transmission shifts, so changing it can change how the car drives.

Term

emissions front

“Emissions front” means the part of the business focused on meeting pollution rules. Here, it’s about how those rules affected what they could do.

Term

emissions laws

Emissions laws are rules about how much pollution a vehicle is allowed to produce. They can affect what kinds of modifications are permitted.

Term

stock vehicle

Stock vehicles are cars in their original, factory setup. The speaker is comparing them to modified cars to see what changes after you add parts.

Term

NHTSA

NHTSA is the U.S. government agency that focuses on vehicle safety. When rules about modifying cars come up, they’re one of the main groups involved.

Term

FIA

The FIA is a major international organization for auto racing and safety standards. It’s brought up here because safety rules and standards can affect both racing and road vehicles.

Term

adaptive cruise control

Adaptive cruise control is cruise control that can slow down and speed up to keep a safe distance from the car in front. If you modify the car, the sensors may need recalibration so it keeps working correctly.

Term

lane keeping assist

Lane keeping assist is the system that helps keep the car from drifting out of its lane. It uses sensors to watch the lane lines, and modifications can throw off that sensing.

Term

automatic emergency braking

Automatic emergency braking is a safety feature that can brake for you if it thinks you’re about to hit something. If the car’s sensors aren’t calibrated correctly after changes, it may not work as intended.

Term

rear cross traffic alert

Rear cross traffic assist helps warn you about cars coming from the sides while you’re backing up. If you modify the car, the sensors may need to be checked so it can detect correctly.

Term

recalibrate

Recalibration means re-tuning the car’s safety systems so they “read” the sensors correctly. If you change something on the car, the system may need to be recalibrated to work right.

Term

federal motor

This is referring to U.S. federal rules for vehicle safety. The speaker is saying that modifications have to fit within those legal requirements.

Term

catalytic converter

A catalytic converter is a part in your exhaust that helps clean up the gases coming out of the engine. If it wears out, your car can fail smog/emissions tests.

Term

useful life of 150,000 miles

Regulators set a mileage range where an emissions part (like a catalytic converter) is expected to work well enough to meet the rules. After that mileage, the car may fail emissions testing and you may need to replace the part.

Term

smog test

A smog test checks whether your car is polluting too much. If your emissions system isn’t working well, you may have to fix or replace parts to pass.

Chrysler 2005 Chrysler

The Chrysler 200 is a midsize sedan, meaning it’s a regular passenger car with room for everyday driving. The podcast mentions it in a context that sounds like they’re talking about older Chrysler models. If you’re shopping used, it’s mostly about whether the specific year you want has been well maintained.

2005 Chrysler 300
Car

2005 Chrysler 300

The host mentions a 2005 Chrysler 300 to ask whether older cars get treated more leniently over time. The point is whether emissions rules change just because the car is older.

Term

emissions systems

Emissions systems are the parts on a car that help keep exhaust pollution under control. The host is saying that for many older cars, you’re expected to keep those parts working the way they were originally certified.

1986 Monte Carlo
Car

1986 Monte Carlo

The host brings up a 1986 Chevrolet Monte Carlo to explain emissions rules for older cars. The idea is that you can’t just remove or heavily change emissions equipment—you’re expected to keep it working like it was when the car was certified.

Term

crate engine

A crate engine is a new engine you can buy ready to install, like it’s shipped in a crate. The host is saying regulations may not fully match how easy it is to buy and swap modern engines.

Term

over the counter EFI system

EFI means the car uses electronics to deliver fuel instead of a carburetor. “Over-the-counter” just means you can buy the kit without needing a custom shop build.

Term

direct injection

Direct injection is when fuel is sprayed straight into the engine’s combustion area. It helps modern engines run cleaner and more efficiently, but it can be harder to modify because the electronics and tuning matter a lot.

Term

helicat

“Helicat” is a fan nickname for Dodge’s Hellcat cars—big-power muscle cars that came from the factory. People used to be surprised by how much power they made with a warranty.

Term

California compliant EOD crate motors

These are crate engines that are approved to pass California emissions rules. The approval usually depends on the whole setup, not just the engine.

Term

wiring harness

A wiring harness is the set of wires that connects the engine to the car’s electronics. For an emissions-approved swap, the correct harness matters because it helps the engine and emissions systems work the way they were certified to.

Term

EO number

An EO number is a California emissions approval ID. If your engine swap has the right EO number, the smog shop can verify it’s legal for emissions testing purposes.
