For anyone working on diesel vehicles, especially modern ones packed with complex systems, having the right diagnostic tools is crucial. When I first got my 6.0 diesel, I knew I needed a way to read fault codes and keep an eye on engine parameters. Like many, I turned to FORScan, a software known for its in-depth capabilities. Using FORScan on my computer in the shop is fantastic for detailed work. I used it with the OHP Ford ELMConfig USB adapter which was straightforward and reliable for shop use.
However, the need for constant computer access isn’t always practical, especially for quick checks or monitoring while driving. That’s where the convenience of a smartphone app comes in. While my long-term plan involves integrating a Mini ITX PC into my truck for permanent gauges, for now, a portable solution is key. To achieve this portability, I decided to explore smartphone-based scan tools and apps, and I’m currently testing the OHP WiFi Ford ELMConfig adapter with my iPhone 6+.
The advantage of using a “Best Diesel Scan Tool App” on your phone is clear: it offers unparalleled portability. You can quickly diagnose issues, monitor engine health parameters in real-time, and even clear codes right from your mobile device. This is incredibly useful for both pre-trip inspections and on-the-road troubleshooting. I plan to test various monitoring apps compatible with this WiFi OBDII adapter and share my findings, including the pros and cons of each. It’s worth noting that apps requiring proprietary hardware, like DashBoss or BlueDriver, won’t be part of this review as the focus is on app-based solutions working with standard OBDII adapters.
If you’re considering a similar setup, especially if you are an iPhone user, it’s critical to know that many Bluetooth OBDII readers are not compatible with iOS devices. This is a known limitation due to Apple’s Bluetooth protocols. WiFi OBDII readers, on the other hand, generally bypass these iOS compatibility issues, offering a more reliable connection for diesel scan tool apps on iPhones and other iOS devices. However, always double-check compatibility to ensure a smooth experience.
**EDIT**
I also want to commend the customer support from the company where I purchased the OBD adapter. Their responsiveness to my questions has been exceptional. We’ve had a helpful exchange, and they are even providing me with the WiFi version of their adapter to test and give feedback on its compatibility and performance. This level of customer engagement speaks volumes about their commitment to product quality and customer satisfaction, which is a significant factor when choosing your diesel scan tool solutions.
