ECUType / OMEX600And710

OMEX 600 & 710


Compatibility


  • OMEX 600
  • OMEX 710


Configuration


You must be using the following ECU firmware versions:

  • OMEX 600 - V0.70D or later
  • OMEX 710 - V0.70C or later

The firmware version is marked on the serial number label of your ECU. If you have the wrong firmware version, your ECU must be returned to Omex for a version change.

If you already have an ECU on the above correct firmware version and want to setup your ECU calibration for communication, contact Omex or Race Technology support for a Serial Telemetry Setup file (STS) and follow the instructions:

  • Open the MAP3000 or MAP4000 software.
  • Send your calibration to the ECU by clicking ECU | Send New Calibration (ECU | Connect | cannot be used!).
  • Select Telemetry and Serial Telemetry Setup.
  • Click Import Channel.
  • Select the STS file you have been sent via Omex or Race Technology (RT_DASH2_12Channel_600.sts).
  • Click Open and Close.
  • Go to the Dashboard tab and set Tele1 Chan 0 and Telemetry UART to ON.
  • Save the calibration selecting File | Save As.
  • Send new calibration by closing down the ECU software, reopening it then following the above first step.
  • When sent disconnect from the ECU software and power cycle the vehicle ignition.

When setup correctly the Serial Telemetry Setup will look as below. Baud rate is set to 38400 baud with standard checksum. Start byte must be set to 0x00:

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


Connections


The Omex 600 & 710 ECUs should be connected via RS232 (serial) connections. Race Technology can supply connection cables to suit a direct connection or connection via an ECU Serial Interface:


Data Channel Listing:


The data is translated in the following manner:

ECU Message Name Race Technology Data Channel Resolution of Data
Air temp Ambient air temp (temperature 1) 0.1 oC
Air pressure Ambient air pressure (pressure 1) 1 mBar
battery Battery voltage (misc 3) 0.01 V
Fuel 1 PW Fuel inj 1 PW (aux 6) 1 ms
Spark adv (map) Ignition angle (angle 2) 0.1o
RPM 50 RPM (Engine RPM) 0.1 Hz
Map as Load Boost pressure (pressure 5) 1 mBar
Coolant Coolant temp (temperature 8) 0.1 oC
Lambda1 Lambda 1 (misc 1) 0.01 lambda
Throttle Throttle position (aux 1) 0.1%
Lambda2 Lambda 2 (misc 2) 0.01 lambda
Lambda Target Tyre 1 temp (temperature 12) 0.01 lambda

Not all channels listed in the table above may be available from your ECU. The available data channels vary with the vehicle model, year of manufacture & connected sensors.

Notes:

  • A CD packaged with the ECU, contains both a Telemetry and Non Telemetry base map, for connection to Race Technology Products it is imperative that the Telemetry base map is used as a starting point for the tune.
  • 600 ECU must be v0.70D or later. The letter will not appear in the software, they need to look on the ECU itself.
  • 710 ECU must be v0.70C or later. There were no non-working versions of 0.70 on the 710 so if it shows 0.70 in the software it will be fine.
  • If your OMEX 710 ECU is running version 0.89 firmware or later your will need different firmware on your Race Technology ECU Serial Adapter. Please specify this when ordering or contact Race Technology if you require the alternative firmware for your ECU Serial Adapter.
