  • Stinger 8860
  • Stinger 6860
  • Stinger 4860


ECU configuration not required. The data output rate from the ECU is set at 19200 baud, which is compatible with the Stinger ECU and some versions of the 8860 ECU.


This ECU should be connected via RS232 connections:

The ECU features a female DB9 connector. Race Technology can supply a communication cable upon request, this will connect the ECU serial port to the Race Technology product. If connecting without the RT cable, the pinout information is as follows:

  • RX - Pin 2
  • TX - Pin 3
  • GND - Pin 5
