The LNC-TRM-LS9A, or Torque Reduction Module, is a timing retard controller designed to be used on GM LS9 or LSA engines with OEM engine management systems. LNC-TRM-LS9A provides adjustable timing retard control with up to 50 degrees of timing retard authority. Pictures shown are actually the L460285297 designed for all other LS engines.
This timing retard can be used to reduce engine torque for external
traction control systems or to perform a momentary torque reduction event during a gear change. The length of the torque reduction event can be controlled by the LNC-TRM-LS9A or it can be controlled by an external device including traction control modules, nitrous controllers, or transmission controllers.
The LNC-TRM-LS9A reduces engine torque via ignition timing retard, not via an ignition cut. This makes it compatible with gear shift torque reduction strategies on vehicles equipped with catalysts.
NOTE - if you are looking for a timing retard controller purely for nitrous or turbocharged/supercharged applications and 15 degrees of timing retard authority is enough then you may want to consider the
LNC-2001 L460216509 instead of the LNC-TRM-LS9A.
