ECU and TCU service prices

Stage 1 recalibrates the ECU software without requiring mechanical changes. The aim is stronger power and torque while staying within sensible limits for the specific setup.

Stage 2 is intended for vehicles with suitable hardware upgrades, usually an intake and downpipe. DPF/GPF or catalyst removal is not included automatically; select those services separately if required.

Software calibration for an automatic transmission. Availability and the changes that can be made depend on the TCU model and vehicle setup.

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

FlexFuel allows the vehicle to run on regular petrol, E85 or a mixture of the two. Fuel and ignition are adjusted for ethanol content; compatible hardware and prior confirmation are required.

A ready-made TCU calibration matched to a Stage 1 ECU setup. Available only for supported transmissions and software versions.

A ready-made TCU calibration matched to a Stage 2 ECU setup. Available only for supported transmissions and software versions.

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

Disables automatic engine stop and restart when the vehicle is stationary. The exact behaviour depends on what the vehicle supports.

Suppresses only the diagnostic codes you specify. Enter the exact P-codes in the order notes; unrelated faults are not disabled.

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

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

Disables the SCR/AdBlue function in the ECU software. If physical work is required, the file specialist posts the exact steps in the order conversation and notifications, with an email as well if reply emails are enabled.

For a DPF/FAP that has been physically removed or emptied. Disables filter management and regeneration. Sensor instructions are posted in the order conversation and notifications, and by email if reply emails are enabled.

Disables EGR control in the ECU. If physical work is required, the file specialist posts the exact steps in the order conversation and notifications, with an email as well if reply emails are enabled.

For an OPF/GPF that has been physically removed or emptied. Disables filter management and regeneration; if the catalyst has also been removed, add Decat (CAT OFF).

Disables NOx-system diagnostics and warnings on compatible ECUs. Sensor instructions are posted in the order conversation and notifications, and by email if reply emails are enabled.

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

Disables the raised-idle cold-start routine, usually for vehicles with a modified exhaust system or downpipe.

Software adjustment for a removed catalyst or fitted downpipe, preventing related diagnostic faults and Check Engine warnings.

Adds a brief shift sound on compatible DSG vehicles, where the ECU/TCU and exhaust setup allow it.

Calibration for permanent E85 use only. The vehicle will no longer be set up for regular petrol; choose FlexFuel if mixed fuels are required.

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

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

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

A stronger pops-and-bangs effect created through ignition changes on overrun. Available only from an original file and on compatible setups.

Removes or raises the factory speed limiter where the ECU allows it.
