• Integrates as an “IO Expander Box B”
• Extra values available as “IO Expander Box A”
• Uses values from “Haltech CAN Supported Dash”
• Cut/Blip based on CAN request

CANTCU CAN3 is connected to Haltech 1MB/s CAN-bus.

To achieve a somewhat realistic torque estimation, the ECU VE (fuel) table needs to be tuned and show real-world VE-values. For this torque estimation we use a Torque Factor. The torque factor is generated from engine running values taken from a single point of running (usually maximum measured torque on a dyno run). The values needed for calculation are listed below.

• Maximum Engine Torque (Nm)
• Manifold Absolute Pressure, MAP (kPa)
• Volumetric Efficiency, VE, Fuel Table (%)

Entering these values in the calculation window will generate a torque factor, which will be used as a baseline for torque calculations in the CANTCU.
