Launch control on M150 with OEM speeds sensors Toyota GT86

Hello,

We are trying to implement launch control on a GT86 CS R3 rally car. It seems as the original speeds sensors (abs) were used but since the abs unit is removed the pulse to CAN msg is done by a proprietary PDM system from which we do not have any docs. In the M150 the sensors are configured to Front Left CAN Slot to OE1, FR to OE2, RL to OE3 and RR to OE4. I assume these represents the original CAN ID's coming out of the ABS unit in a normal road car.

Does any one have any knowledge on the CAN Id's used and data structure for those speed sensors?

Thanks in advance
