EMS Stinger and 8860 ECU
The EMS serial – Race Technology interface connects between an EMS Stinger ECU and either a data logger or a dashboard enabling monitoring of all the data channels. The data input rate from the ECU is set at 19200 baud, which is compatible with the Stinger ECU and some versions of the 8860 ECU.
The data sent to the data logger or dashboard is as follows:
| Name
| Race Technology Name
| Resolution
|
| Engine Speed
| Engine RPM (RPM)
| 0.1 Hz
|
| Throttle
| angle 1 (Throttle Angle)
| 0.1o
|
| Barometric pressure
| pressure 1 (Ambient Air pressure)
| 1 mBar
|
| Lambda 1
| misc 1 (Lambda 1)
| 0.01 lambda
|
| Lambda 2
| misc 2 (Lambda 2)
| 0.01 lambda
|
| Air temperature
| temperature 1 (Ambient Air Temperature)
| 0.1 oC
|
| Coolant temperature
| temperature 8 (Water temp)
| 0.1 oC
|
| Ignition
| angle 2 (Ignition angle)
| 0.1o BTDC
|
| Injection time
| measured time 1 (Fuel inj 1 PW on)
| 1 ms
|
| Battery voltage
