| into the main harness of the Z32. The LT12S is Microtechs' latest 6 injector driver, 6 ignition driver ECU
with multiple Auxilliary inputs and outputs. Most often used on 6 cyl and 3
rotor applications but also can be configured for 4 cyl vehicles. Wideband
O2 software and 4 bar map sensor software and loom plug comes fitted as
standard now.
