How a Haltech Nexus map ends up locked
Nexus units are tuned in NSP, and each map is saved as a single .nexmap file.
NSP lets whoever tuned the car put a password on the saved map. Shops do it to protect their work, and the password usually stays with the shop.
The ECU itself is not damaged or locked down. The password sits in the file, so the fix is a copy of that file without it.

Nexus Rebel LS questions
Is my Nexus Rebel LS calibration left as it was?
Yes. Only the password comes off. Every table and setting in the .nexmap file stays as it was.
Do you need the Nexus Rebel LS unit?
No. You keep the Haltech Nexus Rebel LS where it is. We only need the .nexmap file that NSP saved.
What will the read-out show for a Nexus Rebel LS map?
NSP files report their firmware and the kind of lock, so the read-out shows those. Haltech maps carry no model name, so none is shown.
How quickly do I get the unlocked Nexus Rebel LS map?
The read-out comes back while you wait. After you pay $59.99, the download starts as soon as PayPal confirms the payment.
