Autronic Reluctor Interface Modules and Autronic ECUs equipped with reluctor interface functionality, are not designed to work with multi-pulse flying magnet trigger wheels. Such trigger wheels mis-trigger at high RPM if all the magnets are not precisely matched for magnetic flux strength. Experience has shown that after market trigger wheels of this type have not been sufficiently well matched to work reliably with our reluctor interfaces.

Uniformly machined mild steel trigger wheels operating with a matching magnet equipped reluctor sensor, are the preferred choice for reliable triggering. This is also the method most commonly adopted for OEM triggering.

We only recommend using flying magnet triggers for single pulse per wheel rev applications (eg: Camshaft reference pick-up), since no matching is required for a single magnet.
