For a physically removed or emptied DPF/FAP. Disables filter management and regeneration. Sensor instructions are posted in the order conversation and notifications, with an email as well when reply emails are enabled.

Disables EGR control in the ECU. If work on the vehicle is required, the exact instructions are posted in the order conversation and notifications, with an email as well when reply emails are enabled.

For a physically removed or emptied OPF/GPF. Disables filter management and regeneration. If the catalyst has also been removed, add Decat (CAT OFF) separately.

Disables NOx-related diagnostic functions and warnings on supported ECUs. Sensor instructions are posted in the order conversation and notifications, with an email as well when reply emails are enabled.

Disables swirl-flap control. Select this when the flaps have been physically removed or when software deactivation is required.

Disables Cylinder on Demand, the system that temporarily shuts down some cylinders at low load.

FlexFuel supports regular petrol, E85 and blends of the two. The calibration adjusts fuelling and ignition to the ethanol content; compatible hardware and prior approval are required.

After the technical review, any instructions are posted in the conversation for that order. They also appear in your notifications and, if reply emails are enabled, by email.

TCU calibration matched to an ECU Stage 1 setup. Available only for supported transmissions and software versions.

TCU calibration matched to an ECU Stage 2 setup. Available only for supported transmissions and software versions.

Disables the raised-idle cold-start routine. Most often used with a modified exhaust system or downpipe.

Software calibration for a removed catalyst or fitted downpipe. Prevents related diagnostic faults and the Check Engine light.

Adds a brief, distinctive sound during gear changes on compatible DSG vehicles. Availability depends on the ECU/TCU and exhaust configuration.

Calibration for permanent use with E85 only. The vehicle will no longer be intended for regular petrol; choose FlexFuel for mixed fuels.

Changes exhaust-flap control so the valves remain open on compatible setups. Actual operation depends on the fitted hardware.

Activates or adjusts launch control at a preset engine speed. Availability depends on the ECU, transmission and vehicle.

A milder crackle effect with moderate pops on overrun. Available only from an original file and with a suitable exhaust system.

A stronger Pops & Bangs effect created through ignition changes on overrun. Available only from an original file and on compatible setups.

Removes or raises the factory top-speed limiter where supported by the ECU.

Suppresses specified diagnostic trouble codes. Enter the exact P-codes in the notes; unrelated faults remain active.

Disables the MAF function where the ECU and setup can operate without the sensor. Availability is confirmed after the file has been checked.

Corrects difficult hot starting by adjusting the start logic on supported engines and ECU versions.

Adjusts the factory power and torque display on supported BMW, MINI and VAG models. The values are calculated, not measured on a dynamometer.

Disables automatic engine stop and restart when stationary. The function remains off where supported by the vehicle.
