Sélecteur de programme TurboLamik et programmes par défaut expliqués

A TurboLamik TCU ships with eight named programs, P1 to P8, and the selector is the hardware you use to choose between them. The eight names are set in the basemaps: auto comfort, auto sport, semi-manual comfort, semi-manual sport, semi-manual sport+, semi-manual drag, manual drift and dyno. All of them are freely configurable inside TunerPro RT.

The important thing to understand is that the names are a starting point, not a specification. Nothing stops a builder renaming or rewriting every program, so the only reliable way to know what P4 does on a given car is to read that car's configuration.

The eight default programs

These eight are the standard programs configured in the basemaps. Because all programs are freely configurable within TunerPro RT, treat the table as the factory starting point rather than a fixed menu. A car may use P8 for something other than a dyno session, and the only source of truth is the map in the TCU.

How a program gets selected

The selection method depends on what hardware is fitted. A TurboLamik TCU supports several selector types, and each one is enabled in a different part of TunerPro.

That table covers the wiring side. The configuration side sits in TunerPro and differs for each option, so the setting named in the table is the one to look for.

CAN selectors

TurboLamik supports a list of factory CAN selectors. These use the gear selector already in the car rather than adding a separate switch.

The rotary program switch is noted as optional, and it exists because of a limitation in the F series selector. It allows you to extend the number of programs from the default 3 for that selector to the full 8. If you are running an F series BMW selector and want access to P4 through P8, the rotary switch is the addition that gets you there.

Button selection and analog switching

Button select and analog switching both use the value 15 in their respective settings, which makes them easy to confuse.

For button select, you set the program switch to 15 (Program Switch Button) and then set the analog inputs for the buttons. Each button corresponds to an analog input, so the program is chosen by which input is grounded.

For the analog switching selector, you go to Sensor Call, then Sensor Input, then Selector Input, and set it to 15 (Analog input switching). Then in Sensor Call, under Analog Selector, you set the Selector Call for analog input switching.

There is a polarity caution on the analog switching selector that is easy to miss. If the selector specifies GND, enable Invert. If it gives voltage, disable Invert. Getting that backwards will produce a selector that appears to work in the wrong direction or not at all.

Analog selector with a 0 to 5V sensor

The TCU also supports an analog selector fed by a 0 to 5V sensor. Connect the signal from the potentiometer to the analog input, then in Selector Input, set the analog input the potentiometer is connected to.

Calibrate the selector positions in the Selector Call analog setting. The voltage of the sensor should be calibrated across the range 0 to 5V or 5 to 0V, and the voltage in the settings should change rising or falling to match the direction of travel.

That calibration step is what defines where each program position sits. Without it, the TCU has a voltage but no idea which voltage means which program.

Switching programs without a selector

If you do not have a program selector connected, you can still switch programs with the gear selector. The manual states this works in the range D P1, P2, P3, P4, P5.

That gives a modest number of positions through the factory selector, which is enough for basic driving modes. If you need the full eight, you need a selector that reaches them.

Working with the programs in TunerPro

Because the programs are not fixed, the practical workflow is:

1. Read the current configuration from the TCU before changing anything.
2. Identify which program number each driving situation is mapped to on that car.
3. Change the program behaviour in TunerPro RT rather than assuming the default names apply.
4. Confirm the selector input setting matches the hardware actually fitted.
5. Check the calibration of any analog selector across its full travel.

The single most common confusion with TurboLamik programs is assuming the names are permanent. The manual is clear that they are basemap defaults and that the whole set is configurable.

Frequently asked questions

How many programs does a TurboLamik TCU have? Eight in the default set, P1 to P8. The rotary program switch is described as optional and extends the number from the default 3 for an F series selector to all 8.

What are the eight default program names? P1 auto comfort, P2 auto sport, P3 semi-manual comfort, P4 semi-manual sport, P5 semi-manual sport+, P6 semi-manual drag, P7 manual drift and P8 dyno.

Are the default program names fixed? No. They are standard programs configured in the basemaps, and all programs are freely configurable within TunerPro RT.

What setting enables button select? Set the program switch to 15 (Program Switch Button), then set the analog inputs for the buttons.

What should I set for an analog switching selector? In Sensor Call, Sensor Input, Selector Input, set it to 15 (Analog input switching). Then configure the Selector Call analog input switching under Analog Selector. Enable Invert if the selector specifies GND, disable it if it gives voltage.

Can I change programs without any selector fitted? Yes. The manual states that with no program selector connected you can switch programs with the gear selector in the range D P1, P2, P3, P4, P5.
