OEM source: Yes = tooth count supported by manufacturer documentation; No = aftermarket/independent reference; Mixed = OEM applicability combined with an independent tooth-count reference; Estimate = derived and must be confirmed. This status describes the evidence source—not whether the installed flywheel is original.

Protocol audit — August 5, 2026: Yes = documented native/output support; Gateway / Optional = an OEM or external interface is required; Application dependent = the exact suffix, ECU, year, or package must be checked; Internal CAN / not confirmed = a CAN-based control system exists but a public, customer-accessible J1939 port was not confirmed; No native = no built-in support in the listed configuration. A gateway may still be possible.
