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 interferance.
• 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
