Which OBD2 reader is compatible with a Chevrolet Corvette C8 E-Ray?

For the C8 platform, including the E-Ray, the overwhelming community consensus points to the OBDLink MX+ as the most reliable Bluetooth scanner. E-Ray owners are already using it ⁵, and it has a proven track record of successfully reading and clearing codes on the C8 where cheaper readers sometimes fail ⁹.

Because the E-Ray has unique hybrid subsystems, the hardware dongle is only half the equation; what you can actually see will depend on the app you pair it with (like the native OBDLink app or Torque Pro) ⁵. Any standard ELM-based reader will pull standard engine and emissions codes, but you'll need robust software to dig into the hybrid modules.

Here is how the rest of the options break down depending on what you want to do:

• For Advanced Diagnostics & Bidirectional Control: If you want to do more than just read and clear codes—like transmission fast relearns, fluid flushes, or leak testing—you'll want a standalone bidirectional tool. The XTOOL D8S ² and the LAUNCH X431 Elite ⁹ are both confirmed to handle these advanced procedures on the C8.
• For Basic Code Reading on a Budget: If you just want a cheap standalone tool to keep in the glovebox for a Check Engine Light, the Autel AL319 or the CGSULIT SC204 will read and clear basic codes for around $30 ⁷.
• What to Avoid: The BlueDriver is a very popular Bluetooth scanner, but multiple C8 owners have reported that BlueDriver's tech support admits their GM database only officially goes up to the 2019 model year ⁸. While some guys still use it for basic codes, it's not the best bet for a brand-new E-Ray.

A quick tip on the C8 OBD2 port location: The port is located under the dash to the left of the steering wheel, right below the electronic parking brake button. It's in a spot where your foot can easily kick a Bluetooth dongle when you're getting in and out of the car. If you plan on leaving an OBDLink MX+ plugged in while driving, grab a 12-inch low-profile OBD2 extension cable so you can stash the scanner further back out of the way ³.
