Haltech map unlock for tuners and workshops
We unlock Haltech NSP maps that someone else protected, so the car on your hoist can be tuned again. Drop the .nexmap in the Haltech tray and read the desk’s report on it before any money changes hands.

How NSP locks a map
NSP stores the protection inside the .nexmap itself. Whoever saved it last can set a password, and without it NSP will not show the tables.
Nothing on the ECU has to change. You get the same .nexmap back with the protection removed, ready to load in NSP and connect as usual.

Haltech questions
- Which Haltech files go in the Haltech tray?
- NSP files: .nexmap. Send the file as NSP saved it, not an export or a screenshot.
- Does the Haltech unit need to be on the bench?
- No. Only the file travels. The unit stays in the car until you are ready to connect.
- How long does a Haltech read-out take?
- The free read-out normally comes back within a few seconds of the upload finishing.
