What is Mainline’s New CAN Control System?
Mainline’s new CAN Control System is a sophisticated digital bridge that allows a dynamometer to talk directly to a vehicle’s internal computer network. Instead of relying on external sensors to guess what the engine is doing, the dyno now reads data straight from the source. This system utilises the Controller Area Network (CAN bus), which is the high-speed communication highway found in every modern performance car. By tapping into this digital stream, we get a level of transparency that was simply impossible a few years ago.
To see this technology in action and understand how it changes the tuning landscape, watch this helpful video from the PRI Show:
At Oztrack in Penrith, we’ve integrated this technology with our Mainline ProHub system. This is particularly vital for high-end VF LSA performance packages where every degree of timing and milligram of fuel counts. This digital interface replaces slow, bulky analogue sensors with a single, high-speed data stream that ensures the dyno and the car are always in perfect sync.
The End of Analogue Signal Noise
Old-school tuning often involved clipping inductive pickups onto spark plug wires to get an RPM signal. In a high-performance engine bay, these wires are surrounded by electromagnetic interference. This often leads to "dirty" data or erratic spikes on a dyno graph that don’t reflect reality. It makes life difficult when trying to smooth out the power delivery on a cammed LS3.
Mainline’s new CAN Control System eliminates this problem by pulling data directly through the OBDII port or by pinning into the ECU harness. Because the data is digital, it’s immune to the interference found in a busy workshop. You get a clean, reliable signal every time, allowing us to focus on the actual performance of your engine rather than troubleshooting sensor errors.
Why High-Speed Data Matters in 2026
Modern ECUs are incredibly fast. They make thousands of adjustments every second to keep your engine running safely. If a dyno logs data too slowly, it might miss a momentary "knock" event or a lean spike that occurs between samples. In the world of high-boost LSA builds, missing that data can be the difference between a successful tune and a broken engine.
This new system ensures the dyno’s data acquisition matches the speed of the car’s processor. It synchronises the hub speed from our ProHub with the ECU’s internal clock. This means when we look at a log, we know exactly what the engine was doing at the precise millisecond the torque was measured. It provides a level of safety and precision that is essential for any serious street or race build in NSW.
How CAN Integration Redefines Dyno Accuracy
Accuracy on a dyno is often misunderstood as just getting a high peak number. Real accuracy is about the precision of the data across the entire rev range. In the past, a slight delay existed between the engine’s reaction and the dyno’s recording. Mainline’s new CAN Control System eliminates this lag entirely, creating a real-time data loop that is essential for high-end builds.
We no longer need to rely on multiple external sensors that can fail or provide "noisy" data. By using a single cable, we capture "hidden" channels directly from the car’s computer. This includes critical metrics like oil pressure, fuel trims, and intake air temperatures. Accessing CAN bus for performance tuning allows us to monitor engine health with surgical precision during every pull.
This technology is a total game-changer for supercharged LSA and forced induction builds. We can see exactly how the intercooler is performing and how the ECU reacts to heat soak. It also perfects our steady-state tuning. We can hold the vehicle at specific load points to map out the cruise and light-throttle areas, ensuring your car drives as well in traffic as it does on the track.
Bi-Directional Communication Explained
The biggest shift is that the dyno can now "talk back" to the vehicle. This bi-directional communication allows the system to trigger specific test conditions within the ECU automatically. It removes human error and ensures 100% consistency across multiple runs. This level of control is exactly how we develop our VF LSA performance packages to such a high standard.
Torque Management and Traction Control Integration
Modern HSVs and Holdens use complex torque models that often "fight" older dynamometers. If the car senses a discrepancy between wheel speed and engine load, it might pull timing or trigger a limp mode. With CAN Control, the dyno sees exactly why the ECU is making these decisions. We can then calibrate the torque models to ensure seamless gear shifts, especially in 6L80E and 8L90E transmissions.
This level of integration ensures your gearbox and engine work in total harmony. If you want to see how this precision can transform your own car, you can explore our tuning services to see the results we achieve every day in our Penrith workshop.
CAN Control vs. Traditional Dyno Logging
The shift from traditional analogue logging to Mainline’s new CAN Control System is a massive leap in workshop efficiency. In the past, preparing a car for a session meant spending significant time under the bonnet. We had to attach inductive pickups for RPM and tap into various wires just to get a basic reading. This old-school approach is slow and often results in "noisy" data.
Digital logging through the Controller Area Network (CAN bus) simplifies the process. We now use a single connection to access the vehicle’s entire data stream. This provides a level of detail that analogue sensors simply cannot match. The following table highlights the key differences between these two methods.
| Feature | Traditional Analogue | Mainline CAN Control |
|---|---|---|
| Setup Method | Multiple hardwired clips and sensors | Single OBDII or ECU digital plug |
| Data Resolution | Approx. 10 to 20 samples per second | 100+ samples per second |
| Signal Integrity | Prone to erratic electrical spikes | Clean, interference-free digital signal |
| Logging Capacity | Limited by physical dyno inputs | 100+ channels logged simultaneously |
Practical benefits of this digital shift include:
No more "sawtooth" power graphs caused by spark interference.
Instant access to factory sensors like oil pressure and fuel temperature.
Faster setup times, allowing us to focus on the actual calibration.
Consistent data regardless of the workshop’s electrical environment.
The Precision Gap in High-Horsepower Builds
A 1000hp LSA build requires much faster safety triggers than a standard street car. If a fuel pump fails at full noise, every millisecond counts. Mainline’s new CAN Control System can detect a fuel pressure drop and abort the run instantly. This provides vital peace of mind for our customers investing in Full Engine Rebuilds in our Penrith workshop.
Streamlining the Tuning Process
Efficiency makes your dyno session more cost-effective. We spend less time troubleshooting sensor connections and more time perfecting the air-to-fuel ratios and timing maps. This standardised data format also improves our remote tuning service. We receive identical, high-resolution logs from clients across NSW, ensuring the same quality tune we deliver in person.
Better Tuning Results for Your LS or LSA
The real value of Mainline’s new CAN Control System is found in the refined driving experience it creates for our customers. While previous sections covered the technical speed of the data, the practical result is a car that behaves perfectly on the street. We use this digital precision to stabilise the "hunting" idle often found in aggressive LS cam upgrades, ensuring your car is easy to manage in Sydney traffic.
For forced induction builds, this technology allows us to maximise the efficiency of the factory LSA supercharger. We achieve this through precise control of the bypass valve, ensuring boost comes on smoothly without the jerky transitions common in lesser tunes. This level of control is essential for maintaining long-term reliability while pushing for higher power figures.
Proven Performance Results
To give you a realistic idea of what to expect, we have outlined typical results for common VF Commodore setups below. These figures represent safe, reliable calibrations performed on our Mainline ProHub dyno in Penrith.
| Vehicle / Engine | Supporting Modifications | Fuel Type | Approx. Power |
|---|---|---|---|
| VF LS3 (6.2L) | Oztrack Cam Package, VCM OTR, Full Exhaust | 98 Octane | 330 – 380 rwkw |
| VF LSA (Supercharged) | Pulley Upgrade, Injectors, cam upgrade | 98 Octane | 460 – 510 rwkw |
| VF 6/6.2 (Harrop Supercharged) | Harrop FDFI2300 or FDFI2650 & cam upgrade | 98 Octane | 480 – 550 rwkw |
Note: Power figures vary based on gearbox combinations. Manual cars typically show slightly higher numbers, while 6L80E and 8L90E automatics require careful torque model calibration to ensure crisp, safe shifting under load.
Refining Drivability and Reliability
High peak numbers mean nothing if the car is a chore to drive. We focus heavily on the "tip-in" throttle response, removing the lag often felt in factory VF calibrations. By monitoring the CAN data, we ensure the air-to-fuel ratios remain stable even during rapid throttle changes, which is the best way to prevent engine knock and ensure longevity.
This intelligent data logging also allows us to account for heat soak in LSA builds. We can calibrate the ECU to pull timing safely if intake temperatures climb too high during a spirited drive through the Blue Mountains. If you want the peace of mind that comes with a scientifically backed calibration, book your dyno session with Oztrack today and see the difference for yourself.

Frequently Asked Questions
What is a CAN bus and why does it matter for tuning?
A CAN bus is the digital communication network that links all your vehicle’s electronic control units together. It matters for tuning because it allows the dyno to read critical data like throttle position, fuel trims, and timing directly from the source. This replaces slow analogue sensors with a high-speed digital stream that provides a much clearer picture of engine performance.
Does the new Mainline CAN Control System work on older cars like a VT Commodore?
The new system is designed for modern vehicles equipped with a Controller Area Network. Older models like the VT or VX Commodore use an earlier communication protocol and won’t benefit from the full digital CAN interface. However, we still achieve excellent results on these older platforms at Oztrack by using our ProHub’s high-resolution analogue inputs and our extensive LS tuning experience.
Is a CAN-based tune safer for my engine than a standard dyno tune?
Yes, it provides a much higher level of safety for your high-performance build. Mainline’s new CAN Control System logs over 100 channels simultaneously, allowing us to spot lean spikes or oil pressure drops that slower systems might miss. We can set automated safety triggers that kill the run instantly if any parameter falls outside a safe range, protecting your investment.
Will I get more horsepower with the CAN Control System?
The system itself doesn’t create power, but it allows us to find more horsepower safely. Better data resolution means we can push the limits of your LS or LSA build with total confidence. We can refine the ignition timing and fuel maps more precisely than ever before, which often leads to better peak figures and a much broader power band.
Do I need any special hardware installed in my car to use this system?
No additional hardware is required for most modern vehicles. We simply plug into your factory OBDII port or connect directly to a compatible aftermarket ECU. This streamlined setup is one of the biggest advantages of the new digital interface. It avoids the need for a "birds nest" of temporary sensors and vacuum lines under your bonnet during the session.
Can this technology be used for remote tuning sessions?
Absolutely, it helps our tune files be more precise before we even start. The high-quality data captured by Mainline’s new CAN Control System makes our remote tuning kits even more effective. Because the logs are so detailed and accurate, we can make precise adjustments for customers across Australia. It allows us to deliver a world-class calibration as if you were right here in our Penrith workshop.
Why does Oztrack use a ProHub dyno instead of a traditional roller dyno?
We use a Mainline ProHub because it bolts directly to your vehicle’s axles. This completely eliminates tyre slip, which is a major issue with high-horsepower LS builds on traditional roller dynos. It provides the most repeatable and honest data possible. This ensures your tune is perfectly calibrated for the road without the variables of tyre pressure or strap tension.
