Hardware:
Auxiliary outputs:

PWM 1 - 4, 9 - 14 and 16 are general purpose switch to ground 1A current limited outputs. PWM 1 - 4 have optional free-wheeling diodes for linear control of variable solenoids. PWM 5,6 and 8 are general purpose switch to power 1A current limited outputs. All PWM channels have 33V flyback limiting. PWM 1 is not available for DBW Cars. PWM 7 and PWM 15 are currently not available.

NTK L2H2 Wideband Closed Loop Autotune:
All Nemesis 2.5 ECUs have an L2H21 driver as standard equipment. There is no need to use an external uego driver module. The L2H2 , a newer more robust version of the L1H1 Sensor is a state-of-the-art Nernst Cell sensor with a rapid response and far more useful rich end output characteristics than older, non-planar sensors. Heater current is limited for a controlled warm up, and voltage limited for constant temperature.

Ignition:
Igniter signals are fully sequential 5V ignition triggers. Firing mode is positive only (voltage output to charge coil). Output options are direct fire, wasted spark and distributor signal.

Support:
Nemesis 2.5 includes many support options that make seamless plug-and-play possible, and wire in trouble free. Advanced support features include a dedicated variable speed fuel pump signal for the WRX, Honda multiplex bus support (for climate control and gauges), dedicated circuit opening relay ground signal and dedicated sensor ground connections that reduce harness ground wire splicing.

Auxiliary inputs:
Aux 1, 2 and 3 are 0 - 5V analog or 0 - 12V digital inputs. In digital mode, the switch point is 2.5V. Aux 3, 4 and 5 are digital only inputs, with a switch point of 2.5V.

Injectors:
The Nemesis 2.5 is capable of running cars up to 8 Cylinders sequentially. Injection modes are sequential, batch fire and throttle body injection. When not used for injection, outputs 2 - 8 can be used for staged injection or general purpose switching, and outputs 2 - 5 can be used for PWM control.

Sensors:
Analog sensor inputs are coolant temp, air temp, throttle position, twin knock sensor, twin ego sensor and on-board 3 bar map sensor. Temperature sensors can be configured for the 2 most common types, and knock sensor inputs can be amplified.

Digital trigger inputs are vss, trig and sync. These inputs are magnetic reluctor, Hall effect or optical sensor compatible.
