Custom Code Supported ECU Software Versions

On this page, you can find if your ECU’s software is supported for a specific Custom Code version. As of Custom Code v7.0.5, all Gen 1 G-Series and F-Series software with SWFL 3076 or 3081, and Gen 2 G-Series software with SWFL 5D55 are fully supported. Support for remaining software versions will be available very soon.

Other Gen 2 vehicles support up to Custom Code v0.5. We are working towards adding v7.x for SWFL 3E7D, 4ACF, & 5C64.

How To Check Your Software Version

You can check which software version you have by using the MG Flasher app: go to the “Diagnostics” page and press “Read” next to “ECU Info”.
