Apexhaus Performance | BMW Calibration Request

Remote BMW Calibration

Review-based tuning for modern B58 and S58 platforms.

Apexhaus Performance is built around careful calibration requests, not instant max-power files. Every order collects the ECU read, vehicle health details, hardware list, fuel target, and power goal before a tune is released.

Select your build

Choose your BMW engine, fuel target, and estimated power range so the request starts with a clear goal.

Submit vehicle data

Upload your ECU read and disclose mileage, hardware, faults, prior tune history, and unlock status.

Review before release

Final calibration targets are set after the file, fuel, hardware, and datalog requirements are reviewed.

Engine and Power Goal

Select engine

Power ranges are estimates for planning only. Final targets depend on fuel, hardware, ECU state, logs, and vehicle condition.

Select tune

Each request starts with review. Aggressive files should never be released without supporting data.
