Engine management EDC also received the upgrade to bring it inline with the rest of the "family" and be TEA 98 compliant. Introduction of D12C engine had created all new beast in its class thanks to its extra power and powerful engine brake which were only available previously in the FH class saw operators with an option of smaller cab but still capable long haul unit particularly with globetrotter cab and indeed FM12 did steal some sales from its bigger brother the FH12.
