Gen3 Cable Throttle Base Map for G4X XtremeX/StormX

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
