TECHNICAL INFORMATION
The standard factory harness arrangement limits ignition and injection to wasted spark and semi-sequential operation respectively. Full sequential conversion requires additional wiring. For boost-control installations, repurposed wiring near the airbox can carry the PWM signal to a suitable solenoid, with a separately supplied switched power feed.
IMPORTANT INFORMATION
Haltech ECU not included.
Factory immobiliser coding is not retained.
Wideband sensor and controller requirements depend on the selected ECU; compatible Nexus hardware may use the ECU's built-in wideband input.
Factory MAP sensing is not suitable for boosted applications; an appropriately rated sensor is required.
A base tune is a starting point only. Installation, configuration and dyno tuning should be carried out by a competent professional.
Confirm the exact model-year and ECU compatibility prior to ordering.
