OMEX 600 & 710

The OMEX 600 and 710 ECUs with V0.70 firmware are fully configurable in terms of which channels of data are transmitted and at what data rate. To be compatible with the Race Technology ECU decoder the ECU must be set up to output the following channels of data:

Byte Name Units Scalar Offset Min Max Signed?
1 Air temp oC 1 0 -128 127 Y
2 Air pressure kPa 0.5 0 0 127.5 N
3 Battery Volts 0 0 0 15.93750 N
4 Fuel 1 PW µs 512 0 0 131070 N
5 Spark adv(map) o 0.3515 -30 -30 59.64844 N
6 RPM 50 rpm 50 0 0 12799.80469 N
7 MAP as Load kPa 0.3922 0 0 99.99847 N
8 Coolant oC 1 0 -128 127 Y
9 Lambda1 Lambda 0.0078125 0 0 1.992188 N
10 Throttle % 0.3922 0 0 99.99847 N
11 Lambda2 Lambda 0.0078125 0 0 1.992188 N
12 Lambda Target Lambda 0.0078125 0 0 1.992188 N

Baud rate is set to 38400baud with standard checksum. Start byte must be set to 0x00

The data is translated in the following manner:

ECU Name Race Technology message Race Technology Default name Race Technology VAR number Resolution
Intake Air Temperature Temperature 1 Temperature 1 VAR_1000 0.1C
Manifold Air Pressure Pressure 5 Boost Pressure VAR_3504 1 mBar
Battery Voltage Misc 3 Battery Voltage VAR_4002 0.01 V%
Fuel Pulse Width Measured Time 1 Fuel Inj 1 PW on VAR_2500 0.1%

RPM Engine RPM RPM VAR_0010 25 RPM
MAP Load Aux 27 Auxiliary 2 VAR_2026 1 mBar
Water Temperature Temperature 8 Water Temperature VAR_1007 0.1C
Lamda 1 Misc 1 Lambda 1 VAR_1000 0.1 Lambda
Throttle Position Aux 1 Throttle Position VAR_2000 0.1%
