GWv4

Calibration software for GEMS engine management systems and transmission controllers. LICENCE PROTECTED
Public Release
Version: 4.05.42
Date: 2026-07-24
Size: 69.26MB
Change Notes

B#6839: XCP: sometimes channels not updating following connect.
B#6832: KMS Tuner / GW crash reports - failure to open comms log can terminate application during connect, possibly due to virus scanner locking the log file. It will now retry for 1s before giving up and reporting the error to the user.
T#5159: Added Pinout View documentation to the manual.
Added properties to pinout view for controlling column widths from scripts and setting an auto-stretch column.
Extended A2L formula evaluator added features: Basic string handling: string literals, string concatenation, string comparison. Keyword: ecu_string('name') to find EcuString type objects in ECU definition. Functions: string, trim, ceil, floor, upper_case, lower_case. Intention is to enable use of strings for conditional loading / logic in EDX files, e.g. to use 'cal name' object for linking EDX files to specific calibration files. EDX files are now loaded from multiple external locations in the following order: '%PROGRAMDATA%\\\EDX %APPDATA%\\\EDX' Updated search wildcards for EDX files to match on both .*edx and also *..*edx to allow for multiple EDX files for the same ECU name, e.g. for different ECU versions.
Additional EDX search paths may now be added in application folder settings.
B#6698: Script editing in external editor could sometimes clear the local copy.
Fixed 'Edit in VS Code' button in script editor for Windows 11.
B#6697: Removed float/un-float from context menu for PC logging and Calibration Compare as not applicable.
B#6609: Reset ''CoPro'' version when connnection to an ECU to avoid this information showing up on subsequent connections to other ECUs that do not have a CoPro.
B#5842: Fix ''last folder'' for Firmware + Secondary firmware in create package dialog.
