Parameters / Torque Calc

Torque Calc

How the TCU works out engine torque, either from the ECU over CAN or from its own internal model. Wrong torque moves every shift point.

12 parameters: 12 documented.

Add CAN Engine Loss (BMW E46 - CAN Type 31)

# 0x1E97
Adds the engine-loss (friction) torque reported over CAN to the torque value. Only meaningful on OEM ECUs that broadcast a loss frame; with an aftermarket ECU it is rarely needed, leave it off.

Automatic detection of torque calculation input

# 0x3872
With this on (10.72+), the TCU falls back to internal torque calculation when no torque frame arrives on CAN. Useful redundancy, but it also lets a broken CAN torque setup go unnoticed, so the internal tables still need a proper setup.

If there is no torque frame in can, the TCU switches to internal torque calculation.

Base Torque Table MAP Correction

Base Torque Table RPM/MAP (ft/lbs)

# 0x76CF 10×17
The ft/lbs view of the base torque table: engine torque by RPM and manifold pressure, for maps running imperial units. Everything that applies to the Nm table applies here, including the rule to overestimate, never underestimate.

Base Torque Table RPM/MAP (NM)

# 0x4058 10×17
The heart of internal torque calculation: engine torque (Nm) by RPM and manifold pressure. The pressure axis tops out at 100 kPa (atmospheric); boost is handled entirely by the MAP correction multiplier. The vacuum cells produce negative torque and matter for engine-braking clamp, so leave them alone.
Overestimate torque, never underestimate. Too high reads as harsh shifts but is safe; too low means clutch slip and clutch damage. Before driving or adapting, verify dash Engine TQ reads 10-20 Nm at idle and at held 3000 and 5000 RPM: reading high, trim those cells down; reading low, raise them.

Max TQ TPS Limit (FT/lbs)

# 0x3203 7×17
The ft/lbs twin of Max TQ TPS Lim (NM); use whichever unit set your map runs. Same diesel caveats: still multiplied by the MAP correction, and since 10.72 the base maps no longer carry a diesel-specific calibration here. The shipped table is a generic placeholder identical to the petrol map; fill it for your engine before relying on it.

Max TQ TPS Limit (NM)

# 0x3A4 7×17
Torque ceiling by throttle and RPM. With the Use Table flag on it becomes the primary torque source for diesels and other engines without a usable vacuum signal.
It is still multiplied by the MAP correction even as the primary source. Since 10.72 the base maps no longer carry a diesel-specific calibration here: the shipped table is a generic placeholder identical to the petrol map. Fill it for your engine before relying on it.

Offset Engine Torque

# 0x6A21 1×1
A flat Nm offset added to the calculated torque. It is a diagnostic tool: temporarily add 250 Nm everywhere, and if clutch slip disappears your base torque table is too low.
Never leave a value in here on a finished map. Fix the base table instead.

# 0x7398 1×1
Where the TCU gets engine torque: 0 = internal calculation from MAP, RPM and TPS; 1-3 = one of the CAN torque channels, multiplied by the correction tables. Most standalone-ECU installs run internal (0); only select OEM profiles send a real torque frame.
