Link PCLink 7.6.6 / G4X 6.29.6 adds Voodoo Neo and Haltech iC-7 support

Release supports Voodoo Neo 4/6, new Porsche CAN modes and Math Block functions, and can receive button presses from Haltech iC-7 dashes.

Link ECU released PCLink 7.6.6 on 18 August 2025, alongside G5 firmware 7.6.6 and G4X firmware 6.29.6. It superseded the short-lived 7.6.5/6.29.5 build and rolled up all changes since 7.5.1.

The biggest addition is support for the new G5 Voodoo Neo 4 and Voodoo Neo 6 ECUs, including their configurable ADIO pins, Ethernet connection and improved logging with real-time clock time stamps. The update also lets Link ECUs receive button presses from Haltech's iC-7 dash.

Other new features include reworked Porsche CAN modes (split into Cayman/Boxster and 911, which existing users must reselect), min, max and equality functions in math blocks, a target gear runtime for gear shift control, a check engine light output for 2007 to 2014 Subaru WRX CAN modes, a direct injection pump type for Bosch HDP2.5 pumps used on engines such as the BMW N73 and Alfa JTS, CAN-writable tyre pressure values including GT86 TPMS, 32-bit custom user CAN values, opening multiple logs at once and partial log export. A fix for the Mitsubishi Evo X trigger mode changed its built-in offset by 360 degrees, so affected users need to adjust their trigger offset, and the GPS time zone offset must also be re-entered.
