Gen3 Cable Throttle Base Map for G4X XtremeX/StormX
Advanced features of the XtremeX ECU:
- Fully programmable E-throttle control complete with capability of gear shift throttle blip and antilag.
- Cruise control.
- Two independent CAN modules.
- 30 general purpose tables (up from 20)
- All Motorsport features including full gear shift control, cruise control, traction control, antilag and launch control.
- Advanced closed loop lambda strategy and dual bank lambda control.
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 package 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
