ECU Remapping Performance Calculator

ECU Remapping Performance Calculator lets website visitors select a vehicle and view estimated power and torque gains available from ECU remapping. The calculator supports vehicle selection by type, manufacturer, model, year and engine, with configurable presentation options for WordPress websites. Third-Party Service This plugin connects to a service operated by Arrow Design at arrowdesign.ie. The service is used to provide ECU remapping calculation data and to validate access to service features. During validation, the plugin may transmit the configured account email, API key, website URL and information required to determine service access. Vehicle selections required to return calculation data are also sent when visitors use the calculator. The service is required for the remote ECU remapping data supplied by the plugin. If the service cannot be reached, remote calculation data may be unavailable.
