L5P Tuning: Is the wait over?
There may finally be a way to communicate and (more importantly) reflash the “uncrackable” ECU aboard the ’17+ L5P Duramax. SC Research LLC, a company that specializes in reverseengineering virtually any type of automotive computer, was able to infiltrate the L5P ECU and confirm that a different calibration could be uploaded. It’s important to note that SC Research LLC doesn’t write aftermarket calibrations, but that it provides the ability to re-flash to its partners. Still, this is a long-awaited breakthrough for L5P owners and it means that aftermarket tuning is on the horizon.
