Upgrading Your Truck to Comply With New Emissions Standards?

CAI's TMT3978 Translator Relieves the Pain

New heavy diesel emission regulations are pushing truck owners to upgrade their engines, but trading out an engine with a newer model can be difficult and involved. Other components, such as ABS, transmission, and dash computers rely heavily on the original engine for vital information to operate. Engine upgrades often disrupt this link, causing a number of complex problems.

The TMT3978 is a single-device solution that works as a link between the new ECM's J1939 and the truck's J1708/J1587 data buses. With the TMT3978, old, reliable trucks can stay on the road.
