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.

• 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
