VA WRX FA24 Swap Base Map
This base map is made for the Atlas tuning platform, with custom patches engineered to allow the factory VA ECU to control the FA24 hardware.
After purchasing this, I will set up the map and email it to you. This typically takes 1-3 business days, but may be longer depending on my schedule. Please email me if you need it urgently.
Important: This is NOT an OTS Tune or Custom E-Tune. This is strictly a foundational starting point designed for you or your tuner to build on. You are expected to make changes to it to ensure engine reliability.
Key Features:
Corrects internal timing and pulse width logic to grant the ECU proper control over the FA24 high-pressure fuel pump with FA24 camshafts.
Corrects internal timing logic for the camshaft trigger wheels to allow accurate cam position tracking.
Adjusts the TGV position DTC range to match the FA24 intake manifold.
Properly scales the Oil and Coolant temperature sensors to read FA24 hardware accurately.
Updates engine displacement parameters and scales for the FA24 injectors, including injector size and dead time, for accurate fuel calculations.
Airflow and fuel scaling to avoid ECU internal limits.
This base map is meant for people using the following hardware with their FA24 swap:
FA24 Camshafts (including FA24 cam timing plates)
FA24 High Pressure Fuel Pump
FA24 Injectors
FA24 Intake Manifold
FA24 Coolant Temperature Sensor
FA24 Oil Temperature Sensor
FA20 Fuel Pressure Sensor
A note on aftermarket parts:
Your bolt-ons - such as J-pipes, intakes, headers, turbo, intercooler, etc - do not matter for this. The tune requires adjustments to meet your car’s specific needs.
Disclaimer: Off-Road and Racing Use Only
This product is designed and intended strictly for off-road, closed-course racing applications. It is not legal for use on public roads, highways, or street-driven vehicles. The purchaser assumes all responsibility for ensuring compliance with local, state, and federal emissions regulations, including EPA and CARB standards.
Modifying your vehicle's engine control unit (ECU) and operating with aftermarket hardware carries inherent risks, including the potential for catastrophic engine, drivetrain, or component failure. This base map is provided "as is" and is explicitly not a finished tune. NTMotorsports LLC assumes no liability for any vehicle damage, loss of factory warranty, personal injury, or legal consequences resulting from the installation, subsequent tuning, or use of this product.
