Hey! About a year ago I showed some work getting a Sync 4 APIM and IPC from an S650 (2025 Mustang) powered up and talking on the bench. Since then I’ve finished a setup that lets you do this with pretty much every module including various IPC, SYNC 3, SYNC 4, FCIM, etc. across most variants. You can also control the whole bench using simple serial commands. I’m looking for feedback on improvements and features. Thanks.
Bench harness wiring diagrams will be up soon to attach for Sync 3, Sync 4, & IPC Modules
check it out. It boot sync 3 devices easily, but have had some challenges booting Sync 4. Seems I can boot early models, but not some>2023. Let me know if you have any insight into wake and keep-alive CAN messages for Sync 4 please.
