Notes
Auto-mapped by auto_map() from the library pin data on 2026-10-04. Review every wire against both manuals before building. Not wired: - OEM-B 21: Backup power (battery constant): MaxxECU MaxxECU GEN2 TRACK has no battery-constant input; not needed - OEM-C 29: Cam (TDC2) sensor +: no free cam_vr/cam_hall/frequency_in input on MaxxECU MaxxECU GEN2 TRACK - OEM-C 3: Knock sensor: 2 stock pins named "Knock sensor" without a documented polarity / pairing; wire by hand - OEM-C 22: Knock sensor: 2 stock pins named "Knock sensor" without a documented polarity / pairing; wire by hand - OEM-A 19: Tacho output: no free tacho/frequency_out/low_side/ls_hs on MaxxECU MaxxECU GEN2 TRACK - OEM-A 21: K-Line: no free k_line on MaxxECU MaxxECU GEN2 TRACK - OEM-A 10: Service check signal: not classified in the library; wire by hand - OEM-A 13: Immobilizer enable signal: not classified in the library; wire by hand - OEM-A 25: Immobilizer code: not classified in the library; wire by hand - MAXXECUGEN2T-MX2 24: 12V supply 3: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
