Questions
Drop it on this page. The viewer reads the file and shows its tables the way NSP lists them. You don't need NSP, Windows or an ECU connected.
Yes. NSP is Windows software, but this viewer runs in any modern browser, so it works on a Mac, a Linux PC, an iPad or a phone.
Yes. Base maps from Haltech's library are .nexmap files saved with NSP, so they open here like any other unlocked map.
Nexus and Elite maps saved with NSP (.nexmap). Older Elite maps saved with ESP (.e550-2xx to .e2500-2xx) and Platinum maps from ECU Manager can't be viewed yet.
Partly. Drop it here and the viewer opens it with part of the real values shown; the rest stay hidden until you unlock it. We remove the password for $159.99, and you only pay if it works.
No. The file is only used to build the view and is deleted right after. We don't keep a copy.
They are read straight from your file and shown with Haltech's own units and decimals. A table we can't read with certainty is left out rather than guessed.
