Installed modules
Not installed or Installed indicates if the module is installed or not.
Note: Make sure connected CAN modules have a stable power supply when MaxxECU is powered and tries to communicate with module, otherwise and error is thrown.
Data transmission
Default CAN output protocol
Specifies the default CAN output protocol to be transmitted.
•Disabled - No default CAN protocol is transmitted.
•MaxxECU Default 1.2 - MaxxECU default CAN data protocol to be transmitted, for example connection to external Dash loggers (AIM, RaceTech eg).
•MaxxECU Default 1.3 - MaxxECU default CAN data protocol to be transmitted, for example connection to external Dash loggers (AIM, RaceTech eg).
•KMS CAN display - KMS CAN Display.
Protocol CAN Bus
Specifies which CAN bus to transmit/receive data on (only visible when more than one CAN Bus line exist in the connected MaxxECU).
CAN ID OFFSET
Specifies an offset value to be added to the above protocol IDs. Both positive and negative values can be used.
Note: Just be careful and make sure you know you are doing :)
Example CAN ID OFFSET usage
KMS CAN Display protocol output, with not offset added.
Example offset of "2".
KMS CAN Display protocol output, with not offset "2".
message rate
Available for the default v1.3 protocol.
•Default (10/50Hz) - 10Hz for the SLOW packages, and 50Hz for the FAST packages.
•User settings - Set custom rate for SLOW/FAST packages.
slow package rate
Sets the speed of all the SLOW packages.
FAST package rate
Sets the speed of all the FAST packages.
Note: To determine which are SLOW/FAST packages, see MaxxECU Default CAN output page.
ODB-2
Enables/disables ODBII data output to enable diagnostics tools. Read disclaimer in MTune.
When CAN OBD-II is enabled, a new setting page under CAN Bus is visible with some options.
OEM CAN protocols
Enables OEM (stock vehicle) CAN data to be transmitted and/or intercepted.

Note: this list will be updated as we extend our support for other vehicles (based on demand).
Instr. cluster fuel flow correction.
Used to correct MaxxECU fuel consumption sent to the OEM dash, make sure to calibrate the MaxxECU fuel consumption before even try to adjust this value.
Note: only available on the supported OEM CAN protocols, so this settings might not be visible for your OEM CAN.
Wheel speed correction.
Used to correct the wheel speed coming from OEM ABS system (not available on all protocols) into the MaxxECU when an OEM CAN protocol is activated.
Verify and adjust the correction (%) value using an GPS or similar to make sure the wheel speed in MaxxECU is accurate.
Note: Make sure to enter correct wheel circumference in Speed/Gear --> Wheel setup before attempting to adjust this correction value.
Coding option
Used on some OEM CAN protocols where there are some "coding" options to make ABS/TC happy. Currently only used (and visible) by the Mazda RX8 protocol.
•Coding 0 (mixed) - Initially we tried to "combine" a few codings we have seen, worked on some models. •Coding 1 (N3H8EM). •Coding 2 (N3H8EGI). •Coding 3 (N3K2 UAE Mazda RX8 JDM). |
CAN powertrain controls
CAN Powertrain control protocols can be combined with the OEM CAN protocols, but be sure to check the documentation.
Power train control
•BMW DCT (GS7D36SG) gearbox control.
•CANTCU.
•VAG Automatic pre 2012 (DQ250/DQ500/ZF 5HP) TCU control.
CAN peripheral controls
•BMW E9x EKPM (Fuel Pump Control Module)
•BMW E85 EKPM (Fuel Pump Control Module)
CAN Shifter protocols
CAN shifter protocol
When activated, the RealTime Data value CAN Shifter Selector Position is updated with position/button data.
Note: The needed CAN messages to wakeup the shifter is automatically transmitted, so pay attention for CAN collisions.
•BMW Fxx DCT
Transmitted CAN ID: 0x12F, 0x3FD, 0x202, 0x293, 0x393, 0x328
Receive CAN ID: 0x197.
Note: Do not activate in combination with the GEN2 DCT.

CAN bit rate
CAN x Bitrate
The CAN bitrate has to be 500Kbit for use with MaxxECU CAN modules and most OEM protocols.
If you're using aftermarket dataloggers or dashes you may want to use another bitrate to match the rest of the system.
Note: Restart the ECU after changing the bitrate.
