MATCHED CALIBRATION SERVICE
A starting map built around your Haltech setup.
Base calibration for supported Elite/Nexus applications, configured from supplied hardware and ECU details. Final vehicle validation is required.
Pre-built starting calibration file for supported Haltech Elite and Nexus ECU applications.

Installation
- Install the correct Haltech software for your ECU generation and connect the ECU with the manufacturer-approved USB/communications cable.
- Save a backup of the current ECU map before importing or uploading another calibration.
- Open the DD84-delivered map and confirm the ECU model, vehicle/engine selection and major sensor/injector configuration.
- For Plug-in/Nexus applications, verify the correct vehicle variant/pin configuration before powering the engine.
- If drive-by-wire is used, complete the required APP/TPS calibration procedure before starting the engine.
- Upload/write the calibration to the ECU and power-cycle as instructed by Haltech software.
- Verify sensor readings, fuel pressure, synchronization, TPS, MAP and wideband operation before starting.
- Start the engine and perform datalog verification before load or high-RPM operation.
Important: Haltech documents that base maps are only a starting point and require appropriate tuning. Incorrect model/variant or sensor configuration can create unsafe operation.
File delivery: the completed Haltech map is sent to the email address on the Shopify order after the required configuration information is received.
