Software calibration can take a lot of time, and customers definitely do not want to see extra miles on their cars when they pick them up. To solve this problem in my own shop, I started using a Mileage Blocker from Dynotest
https://dynotestpro.com/ during our software testing phases. It is a professional-grade module that prevents the car from recording mileage while it is stationary on the rollers. I was really impressed by how well it works because it does not cause any communication errors with our diagnostic software or the factory BCM. It allows us to run the car through endless simulated driving cycles to test our new software maps safely. It is a highly effective way to keep your shop operations clean and your customers happy.
