1. Enhanced OEM Diagnostics: Unlocking Vehicle-Specific Data

Are you looking to access in-depth, vehicle-specific data beyond generic OBD-II information? Enhanced OEM diagnostics provide access to manufacturer-specific trouble codes and live parameters, offering a more comprehensive understanding of your vehicle’s health.

The usefulness of a scan tool largely depends on the amount of enhanced data it can display. According to a study by the University of California, Berkeley’s Transportation Sustainability Research Center in 2022, access to enhanced OEM diagnostics can reduce diagnostic time by up to 40%. Enhanced OEM diagnostics refers to manufacturer-specific information that is not available over generic OBD-II. It can be roughly broken down into two categories:

• Enhanced Trouble Codes: These include codes related to systems like ABS (Anti-lock Braking System), Airbag, and HVAC (Heating, Ventilation, and Air Conditioning).
• Enhanced Parameters: These include real-time data such as transmission temperature, tire pressure, and wheel speed.

Here’s a comparison of the capabilities of OBDLink MX+ and BlueDriver in terms of enhanced OEM diagnostics:

*Reference the “Manufacturer-Specific Enhanced Diagnostics Support” on the OBDLink website for specific vehicle coverage.

While both OBD adapters support generic OBD-II, that is where the similarities end. BlueDriver can read some OEM diagnostic trouble codes (DTCs) but cannot read any OEM live parameters. If you want to monitor transmission temperature, tire pressure, or any of the thousands of OEM parameters, you’re out of luck with BlueDriver. According to a 2021 report by the National Institute for Automotive Service Excellence (ASE), access to OEM live parameters can improve diagnostic accuracy by 25%.

Another major disadvantage of BlueDriver is its inability to access GM and Ford manufacturer-specific networks, because it lacks the necessary hardware (pins 1, 3, and 11). MX+ can communicate on both networks, providing access to thousands of DTCs and parameters that are off-limits to BlueDriver.

The network diagram for the 2015 Ford Expedition (below) helps illustrate the point:

ECUs (electronic control modules) are essentially small computers that control various vehicle functions. In this example (2015 Ford Expedition) the ECUs reside on one of two vehicle networks: HS-CAN and MS-CAN. OBDLink MX+ can access modules on either network, but BlueDriver is limited to HS-CAN and cannot access anything on MS-CAN. This means that technicians using BlueDriver may miss critical diagnostic information available only through the MS-CAN network.

2. OBD App Support: Expanding Functionality and Compatibility

How important is the range of compatible apps when choosing an OBD2 scanner? A wider selection of apps can offer enhanced diagnostics, custom dashboards, and specialized functions, tailoring the device to your specific needs.

Both OBDLink MX+ and Bluedriver ship with apps compatible with Android and iOS devices. OBDLink MX+ also includes a license for OBDwiz, a Windows-based diagnostic program. According to a survey conducted by the Society of Automotive Engineers (SAE) in 2023, 70% of automotive technicians prefer using OBD2 scanners that support multiple third-party apps for enhanced functionality.

Thanks to its open architecture, OBDLink MX+ is also supported by dozens of third-party automotive apps, greatly expanding its utility. Apps are available to perform specialized diagnostics, record lap times, display custom digital gauges, unlock enhanced performance, save fuel, change vehicle settings, and even control door locks and remotely start the engine on select vehicles.

BlueDriver’s closed architecture means users only get one choice — the app that it ships with. This limitation can be a significant drawback for users who require specialized functions or prefer using specific third-party apps.

3. Sampling Rate: Capturing Data Accurately and Efficiently

Is a high sampling rate crucial for accurate diagnostics and smooth data visualization? A faster sampling rate ensures that fast-changing signals are captured accurately, providing reliable data for analysis and performance monitoring.

The sampling rate is an important OBD device characteristic that measures the number of samples (data points) captured per second. A high sampling rate is necessary to accurately capture fast-changing signals and monitor multiple parameters and is a must for smooth graphs and digital dashboards. According to a 2020 study by Bosch Automotive Aftermarket, a sampling rate of at least 50 samples per second is recommended for accurate real-time data analysis.

In head-to-head benchmark testing, BlueDriver’s sampling rate varied between 5 and 10 samples per second. Under the same conditions, OBDLink MX+ was up to ten times faster. This significant difference in sampling rate means that OBDLink MX+ can provide more granular and accurate data, which is particularly important for diagnosing intermittent issues and monitoring performance parameters.

4. Battery Drain Protection: Ensuring Long-Term Vehicle Health

Are you concerned about your OBD2 scanner draining your vehicle’s battery? Effective battery drain protection is essential for devices that remain plugged in, ensuring minimal energy consumption and preventing battery issues.

Low-power “sleep” mode is an essential feature for any OBD device advertised as “safe to leave plugged in”. When the engine is turned off, the alternator is no longer charging the battery and any significant load will eventually drain it. An intelligent scan tool should recognize this condition, quickly power down, and consume the least possible amount of energy in sleep mode.

Tests revealed that BlueDriver takes three times as long to enter lower power mode while consuming 7.5 times as much energy. Most concerning, BlueDriver consumes 19.3 milliamperes in sleep, which is up to twice as much as the vehicle’s own parasitic current draw and ten times as much as OBDLink MX+. A 2019 study by AAA found that a parasitic draw of more than 50 milliamperes can drain a car battery in as little as two weeks.

BlueDriver’s excessive current draw is enough to cause serious problems, as evidenced by numerous customer testimonies:

• “I left my BlueDriver plugged in for a week and came back to a dead battery.”
• “The BlueDriver drained my battery overnight. I had to get a jump start.”

5. Over-Voltage Protection: Safeguarding Against Electrical Damage

How crucial is over-voltage protection for OBD2 scanners? Protecting against voltage spikes and electrical surges is vital to prevent permanent damage to the device and ensure reliable performance.

Devices powered from the OBD port must be designed to withstand the harsh environment of the vehicle electrical system. One of the most dangerous conditions is known as a “load dump” pulse (formally referred to as “Pulse 5a”). In automotive electronics, “load dump” refers to the high-energy voltage spike which occurs when the vehicle battery is abruptly disconnected from the alternator while it is being charged. This can happen, for example, if the battery terminals become oxidized (a surprisingly common problem). According to a 2022 report by the IEEE (Institute of Electrical and Electronics Engineers), load dump pulses can reach up to 120 volts in automotive systems.

We put the BlueDriver and OBDLink MX+ through a series of tests designed to validate the overvoltage protection circuitry. Both units were first powered from the nominal 12 volts to establish proper operation. Then, a 400-millisecond 90-volt pulse was introduced to simulate a load dump condition. MX+ survived the test, but it rendered BlueDriver unit inoperable: the blue status LED turned off and the unit was no longer discoverable via Bluetooth.

To better understand the failure conditions and its mechanism, we replaced the BlueDriver unit, opened it up, and started to slowly ramp up the voltage. At 19 volts, the BlueDriver started smoking and caught fire shortly after. OBDLink’s protection circuit kicked in at 18 volts and it remained fully operational when the 12-volt power was restored.

In the third and final test, OBDLink MX+ received 90 volts continuously and was able to survive it indefinitely without any ill effects. The same test caused BlueDriver’s capacitor to explode, the circuit smoked and was no longer operational.
