Advanced features on the StormX ECU: 

• Built in trigger oscilloscope.
• Onboard Knock Control – support for two knock sensors wired directly to the ECU.  No external amplifier required.
• Boost control can be open or closed loop with up to three switchable tables.
• Idle valve solenoid or stepper motor control.
• Rotary oil metering pump control.
• Most Motorsport features including full gear shift control, antilag and launch control
• Up to 4 fully variable closed loop VVT cams. 

The terminated harness has the following features:

• Designed to match the PC Link base maps IO setup so that most engines can be made to run with minimal adjustments. 

• Provides spare IO via a “Spares” connector — extra capacity for sensors, switches, or custom additions.

• With the addition of the fusebox, this bundle includes main chassis “flying leads” (un‐terminated wires) for essential power and control, including:

  • Large red “Batt+” wire (for ECU main power) 

  • Red-Green “Fan” wire (ECU-controlled +12V to cooling fan), rated 20A continuous 

  • Red-Blue “Fuel Pump” wire (ECU-controlled +12V), 20A continuous 

  • Grey-Black “Ign Sw” wire (to ignition switch) 

     

• Equipped with sealed JPT terminals in the chassis connector (TE Connectivity JPT family), with mating connector specs provided. 

• The harness includes multiple dedicated connectors for key components, such as:

  • Pedal connector (for DBW pedal): 5V, sensor ground, two analog voltage inputs 

  • CAN2 connector: for CAN devices like lambda modules, displays, keypads, etc. 

  • MAP connector: compatible with Link MAP sensors; adapter available for factory LS MAP sensors 

  • Knock sensor connector: supports up to two knock sensors, with adapters available for Gen 3 or Gen 4 factory sensors 

  • Alternator connector: for “F Body” alternators; provides exciter/lamp wire to terminal B 

  • Transmission (“Trans”) connector: for reverse switch, DI, or other functions needing cabin signal 

  • IAC connector: for 4-wire stepper IAC; if no IAC is used, those channels may be used for other functions (boost valve, NOS, etc.)

  • TPS connector: for cable-throttle sensors; if using DBW, may be repurposed

  • DBW (electronic throttle) connector: for DBW throttle bodies, providing analog inputs, 5V, sensor ground; may be repurposed in cable-throttle engines
