How it works

It works with all engine and system configurations: non-PWM, PWM, and PWM with DOD / AFM (cylinder deactivation). On non-DOD units it converts TCC PWM to full-on apply to address code 1870, with optional active PWM.

A dual O-ring end plug and a stick-resistant design give more accurate, reliable operation with DOD or active PWM. It is recommended for supercharged, turbo or nitrous power-adder LS swaps.
