Questions
Drop it on this page. The viewer shows its main tables laid out like PCLink. You don't need PCLink, Windows or an ECU connected.
LinkECU G4X maps saved by PCLink (.pclx), from standalone ECUs such as the Atom, Storm, Xtreme, Fury and Monsoon, and from G4X plug-ins. It shows the main tables: fuel, ignition, lambda target, dwell, cold start and idle, plus boost and VVT tables when your map uses them. Older G4+ and Vi-PEC maps (.pclr) don't open in the viewer yet.
PCLink is Windows software. This viewer runs in any modern browser, so you can read your LinkECU maps on a Mac, a Linux PC, an iPad or a phone.
A password-protected LinkECU map opens the unlock flow: you can remove the password for $159.99, and you only pay if it works. Maps without a password open here in full.
No. The file is only used to build the view and is deleted right after. We don't keep a copy, and the view isn't published anywhere.
No. The viewer is read-only. To change a map or flash an ECU, use PCLink.
