Say goodbye to messy curly cords and more potential failure points.

Steering wheel-mounted controls make it easier to adjust key functions on the fly, but getting those signals from the wheel to the car is not as simple as it sounds. Running multiple wires through a rotating steering column is unreliable, time-consuming, and they can be prone to failure due to the nature of their use. Zestek has developed a CAN-based steering wheel PCB solution (CAN hub) that simplifies installation, reduces wiring complexity, and integrates seamlessly with MoTeC ECUs, dashes, and PDMs.

With only four wires required for full functionality (CAN high, CAN low, power, and ground), this system eliminates the need for bulky wiring looms. The pogo pin system built into the quick-release hub provides a clean and hassle-free connection, removing the need for traditional curly cords. A pre-configured DBC file is available for MoTeC users (and we're sure more in the future), while others can configure the CAN signals using a spreadsheet for quick setup.

Each button and switch is fully customizable, including momentary and latching functions, as well as full-spectrum RGB LED feedback. Paddles can be used for more than just shifting, allowing functions like anti-lag, launch control, and nitrous activation. It is also sim racing compatible, making it easy to use the same wheel for both real and virtual driving while you wait out the winter weather.

Car brands are secretly limiting your car’s potential, and it has NOTHING to do with reliability.

Getting more power out of a factory car can be surprisingly straightforward with the right software (and sometimes hardware modifications), but what goes into developing a proper tune that exploits more potential without pushing the OEM components past their limits?

At SEMA, HPA had a chat with Arin Anhell from APR, one of the pioneers in the European aftermarket tuning market, to find out how they test and develop tunes, what safety measures they implement, and why modern turbocharged engines leave so much untapped potential from the factory.

Also discussed:

• The limits of factory components
• How APR ensures reliability in their tuning
• Why OEMs leave horsepower on the table
• How direct injection affects tuning potential
• The APR Plus warranty program and what it covers

If you're considering tuning your BMW, Mini, Volkswagen, Audi, Porsche, or other VAG vehicles etc this could be a very helpful insight into some of your options from APR and sister company Dinan Engineering.

When Joel Vermiglio isn’t working his day job at McLaren Formula 1, he’s in his Garage 68 Motorsport workshop building an old VW Caddy… with a McLaren twin-turbo V8 in the rear tray, a Lamborghini gearbox, and Porsche 911 suspension.

👉 Use 'JOEL100’ to get $100 off HPA’s Tuning Starter Package: https://hpcdmy.co/starterb

Joel never set out to work in Formula 1 — in fact, he didn’t have any plans to get into motorsport at all. That changed in his late teens when he got into cars, went on to study, and eventually found his way into the industry.

In this conversation, Joel shares his unexpected journey to joining one of the world’s top F1 teams — proving that you don’t need a PhD in mechanical engineering to claw your way to the pinnacle of motorsport.

We also dig into the inner workings of a Formula 1 team, getting as much behind-the-scenes insight out of Joel as we can. From design and build to the day-to-day operations and the brutal pace of life in F1, it’s a fascinating look into what really goes on.

Finally, Joel walks us through his VW Caddy project — a Frankenstein build sparked by spotting a perfectly good(ish) McLaren race motor in the scrap bin at work. Now it’s a running, driving weapon with supercar DNA and a whole lot of DIY ingenuity.

Joel’s been using our courses to learn parts of the build process that he had little experience in, so this chat also offers an interesting look at how what HPA teaches gets applied in the real world.

Is it time to ditch your factory ECU?

HP Tuners is known for reflashing factory ECUs, but now they’re flipping the script with their Core Standalone ECU, a complete engine management system that offers boost control, traction control, nitrous control and more right out of the box.

We stand up (not much seating at SEMA!) with Justin Burt from HP Tuners to break down who this ECU is for, when you should ditch a stock ECU, and what makes CORE different from the competition. Whether you’re pushing 1500hp on a factory ECU or building a dedicated motorsport machine, this discussion covers CAN bus customization, pricing, and potential future support for DI engines.

Building on from the VCM Suite reflash tuning interface, VCM LIVE software ensures a familiar interface for HP Tuners users tuned to the needs of a standalone ECU tuner, while 12 base maps, sample data logs, and beginner-to-advanced tuning modes make it accessible for both new and experienced tuners to learn and grow with.

With Gen 3/4 LS support out of the gate and Gen 3 Hemi & Coyote in development, this is more than just an LS swap ECU. In time and with the backing of a large company like HPT, is the CORE ECU potentially going to become the most versatile standalone ECU yet?

S15 suspension in a 240Z—good idea or nightmare?

Joel Dimmack’s 1971 Datsun 240Z is no ordinary drift car. Running a VR38DETT swap with Garrett GTX3071R mirrored turbos and making 600-700hp, this 1100kg wet monster blends old-school styling with modern competition-ready tech. But is an S15 suspension transplant really the best setup for drifting?

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

We dive deep into the Parts Shop MAX kit, chassis stiffening by Pace Innovations, and the MoTeC M150 ECU tuned by Nick Ashvin at NA Motorsport to see what it takes to make this build work. Plus, we break down the Albins 6-speed sequential gearbox, R32 GTR diff & axles, and the challenges of running an S-chassis suspension on a shorter wheelbase.

Braking is handled by R33 GTST calipers with Project Mu pads and rotors, along with a twin-caliper rear handbrake setup—a must for a competition drift car.

This is one of the wildest Z builds around, and it has presented Joel with some lessons and aspects he would do differently the second time around, but that is precisely what a build like this is all about and how ideas are built into skills.

The performance EV landscape is changing rapidly, and public opinion on electric vehicles also seems to be on the move. How much faster can they go? What are their limitations? Are they even still relevant?

A lot has changed since we first had this week’s guest, Sasha Anis of Mountain Pass Performance, on the podcast back in 2022. This conversation gets us right up to date on where the industry sits now and what it’s going to look like in the very near future.

Sasha has a foot in both the EV and ICE worlds, driving an extremely quick hybrid 350Z race car as well as owning and operating both Mountain Pass Performance and On Point Dyno, so he’s the perfect person to get down into the weeds on the latest automotive tech without much of a bias one way or the other.

In this conversation, we jump straight into just how much things have changed since Sasha was on the podcast only a couple of years ago, discussing the good and the bad consequences of this rapid evolution. We also talk about where it’s all heading next. Is hybrid the way forward? And what about hydrogen? And how much better can EVs actually get?

The chat then turns towards the technical side as Sasha talks us through the basics of an EV system, covering all the major components and their purposes.

We also discuss why it’s so hard to extract extra power out of an EV system and how an amateur enthusiast should go about carrying out an EV swap if they want to actually get a good result.

Why don't OEMs tune for the maximum reliable performance and what's all the fuss about over emissions compliance in the United States 'street legal' modified car scene?

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

Emissions compliance might not be the most exciting topic, but if you're tuning a street car, ignoring it could land you in serious trouble. We're joined by Chris Mountain from ‪@cobbtuning‬ to break down how emissions regulations have changed, what CARB (The California Air Resources Board) EO (Executive Order) certification really means, and how you can still make large power gains while staying '50-state' legal within the regulations the EPA (Environmental Protection Agency) has developed and enforces (like it or not).

Covered during this SEMA show interview is why OEMs tune for lambda instead of maximum performance, how hardware mods like intercoolers and turbo upgrades affect emissions, and the rigorous (and expensive) testing companies like COBB are now going through to ensure compliance. Plus, find out how you can achieve 20-30% power gains without risking fines or legal headaches.

If you're modifying a street car in the USA and need to keep it legal, this is a must-watch.

2000HP, twin turbos, and a manual transmission – is this the ultimate fun off-roader?

A 2000hp twin-turbo Lamborghini V10 in a street-legal off-road monster? That’s exactly what ‪@MorganClarkeDesign1‬ aka MCD1 built with this prototype Range Rover Velar Dakar-inspired hyper off-roader.

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

Designed as a luxury play car rather than a full race build, this machine blends extreme off-road capability with high-end comfort. Featuring a pressurized cabin, air conditioning, full Range Rover infotainment, and an Albins 5-speed synchromesh manual gearbox, it delivers an unmatched high-performance driving experience—whether blasting through dunes or cruising on the street.

Morgan explains the design process, balancing form and function, and why CAD modelling vs. hands-on fabrication played a unique role in the build. With carbon fibre body panels, fully billet CNC suspension, and a fully custom chassis, every inch of this machine has been engineered for both durability and aesthetics.

With just 7 units being produced, this million-dollar build is set to redefine the limits of off-road luxury performance.

What’s the deal with diesel tuning? Is it really that different? Yes… But also no.

This week Matt Smith of Just Autos joins us to discuss all things diesel tuning — operating principles, combustion temperature, reflash options, and a whole lot more.

Use JUST50 to get $50 off HPA’s Diesel Tuning Starter Package: https://hpcdmy.co/dieselstarterb

Just Autos, based out of Queensland, Australia, specialises in diesel performance tuning — but perhaps not the platforms you’re more familiar with.

Matt has gone down the Japanese diesel path — specifically Toyota’s Hilux, Prado, and Landcruiser platforms. These workhorses are common on Aussie roads, and Matt is at the very forefront of developing their stout Toyota diesel motors to get the absolute best performance from them. 

In this conversation, Matt tells us how he got into the business, and how it’s changed and improved to become the very professional outfit it is today.

We then jump into the real meat and potatoes of this episode — a very deep dive into the world of diesel engines and tuning.

Matt takes the time to really go through how a diesel engine operates and how that differs from a petrol engine, as well as why we need fuel pulses, the general dos and don'ts of diesel tuning, controlling combustion temperatures, and the usefulness (or not) of exhaust gas temperature sensors in a diesel application.

Matt is a great communicator and manages to get tech heavy without leaving the real world, so if you’ve always wanted to better understand diesel technology and how to get the absolute most performance out of it, this episode is a great place to start.
