BMS catalogue records
The TuningService catalogue groups the separately recorded BMS43 and BMS46 engine-control identities with an existing generic BMS import. Browse the BMS catalogue group for current records.
These names are kept as separate catalogue identities. The generic import includes identifiers that need individual review, so the group does not establish that all recorded parts or applications are interchangeable.
One listing for Bosch 0261203447 also uses the designation M1.7.2 alongside BMS43. This is an example of overlapping terminology, not proof that all M1.7.2 and BMS43 records are identical; the link requires further review.
