How to Enable Master/Slave Security on a Tune File | HP Tuners

💻 Remote Tuners--looking for a way to protect your calibration/tune files? Use the Master/Slave Locking feature in VCM Editor to do this! 🙌 This feature allows you to restrict who can write the file that you're sending as well as what vehicle it can be written to and the write method (Write Entire vs. Calibration Only).

This feature is especially useful for tuning shops sending files to remote customers, but anyone can use it!

Everyone it saying that this it “terrible” but it’s one of the best things HPtuners has, it allows tuners and calibrators that have spent years of researching how to properly tune to keep their methods of tuning safe from “copy paste” so called “tuners”

I tried this just because the guys were far away that I needed to write to if I already paid to license their car and I use this feature so they also need to pay to license the file in order to write to it ?

The file .hpt or .rtd can't be modified ok by the customer, ok. But if the ecm is reread, is the file locked or corrupt (checksum) ?

I would not deal with any tuner that tries to lock the file. I am a tuner so I don't really have that problem. You should ask your tuner if he is going to lock the file, if the answer is yes then you should find a new another tuner.

This is lame. As a tuner, I would never do this. As a customer, I would never do business with a tuner that restricts use of the file

If you're not locking tune then you are probably are using someone else's base tune and just tweaking spark and fueling and have no real time invested. No reason to send it out unlocked. If customer gets different mods or moves they have to pay again!

As a tuner, i wouldn't do this to a customer, as it would put him/her in a bad situation if they moved Nd got new mods. Bad idea HPT.
