Supported Haltech NSP files
Current support is limited to the original .nexmap file used by Haltech NSP. Upload the original map through the intake form; keep a private backup before you submit it. We work with the map you upload; this service does not read a locked ECU remotely. Other Haltech file formats are outside the currently confirmed scope.
Map files vary, so we do not claim support for every Haltech product, NSP version, or calibration situation. A manual review comes first and determines whether the request can proceed.
The Haltech free test
The free Haltech NSP test gives a useful, non-password preview from a reviewable file: engine configuration details including cylinders, firing order, capacity, compression and aspiration where available. This helps identify the submitted map and shows that it can be inspected without treating the test as a full unlock.
Full recovery costs $100 USD per map. If the review can proceed, cryptocurrency payment is arranged once the map is ready. You can decide whether to continue after reviewing the free-test result.
Manual recovery and delivery
Your request is reviewed and processed personally. On successful completion, support returns a separate .nexmap file with password protection removed. Password removal preserves the submitted calibration. Open the returned copy in your usual software and check it against your original before using it.
There is no promised turnaround time or universal success rate. You will receive an email receipt with a request reference after submitting, and support will use that email address for review updates, payment arrangements where applicable, and delivery.
Submit only authorized files
By submitting a map, you confirm that you own it or have permission to request this work. You need an existing .nexmap file to submit a request. Include only the information needed for the review, and retain your own backup of the original.
For more detail before submitting, read our Haltech NSP password-removal guide or compare this request with LinkECU map recovery.
