Inputs (working)
•Autogearbox VSS Speed (vehicle speed).
•Autogearbox VSS Gear.
•AC request/idle up.
Outputs (working)
•Tachometer (RPM).
•Engine temperature.
•Automatic gearbox control (with torque table option).
Not working/issues/work in progress
•OBDII works only when CAN wired to OBDII connector (requires JMTII terminals).
Changelog
Wheel speed correction function added in MTune 1.142.
Increased line pressure (for auto gearboxes) possible in MTune MTune 1.134, see below for examples.
Supported in MTune 1.116.
Confirmed to work models
•Nissan Patrol TB48 Y61, ECM model number: MEC 23-052, A1, 2808
Arrow explanation
Green (light): Working.
Green (dark): Working (but not controlled by CAN).
Blue: Not ECU controlled.
Orange: Partly controlled by MaxxECU.
Yellow: Turned off.
Example of the dash output during idle with MaxxECU RACE installed.
Torque Table
Example torque table which is used to control the gearbox on the TB48.
Note: In MTune 1.134 we added the possibility to to go beyond the 100% limit in this table to get more gearbox line pressure.
Note: 0-200% values can be used, where 200% is the maximum pressure sent to the TCU.
Note: a ~10% higher torque value than stock is transmitted when entering 100%.
Note: if no table is associated with the CAN System Torque Value, we send 100% torque continuously.
Wheel circumference must always be calibrated using an OEM CAN protocol
When we calibrate the wheel speeds from an OEM vehicle (to make an OEM CAN Protocol), we always use the stock wheel sizes, so to get correct wheel speeds within MaxxECU, you must calibrate your wheel dimensions, since they are used to show you the correct speed in MaxxECU.
