ECU Connect has some basic functions which you or a tuner will want to use to help dial in your tune. These basic features the data logging and Diagnostic Trouble Codes (DTC) reading and Clearing DTC’s. If your tuner advises you when and what needs to be logged this article will show you how to set up and make a log, it also covers how to read, clear and send DTC reports. To find your tuner look in the soft case that the hardware came in or check the custom input screen within the ECU Connect App.
Making a log with ECU Connect
Making a log with ECU Connect is a simple process, the first step is to correctly connect with the car (shown in the ECU Connect Quick Start Guide article) once the connection is established go to "my car" and "data logging" mode.
Once you have selected data logging live data from the ECU is requested, although at this point it is not recording any information. The next step is to add and remove the specific logging parameters requested from your tuner by selecting the settings wheel (1) and choosing the requested parameters. In general the default logging list is OK however, specific parameters may be requested by tuners to assist in the tuning process.
The speed of logging is effected by the number of parameters selected, less parameters increase the logging speed and more selected parameters will decrease the speed.
Once the required parameters have been selected go back and then press the start logging button (2). This will start storing logged data in a csv on the devices hard-drive. The tuner will usually request the logging to be performed under a series of different driving parameters. For example, idle, light load cruise and then two power runs, they know what the are looking for so will target the areas that are most important to them.
If you have a specific issue that has occurred during the tune you could try logging with either default or specific parameters selected and using the "add mark" button to highlight the exact time an issue occurs and then send it to your tuner as well, this will help them diagnose and solve any issues.
Sharing your logs with your tuner.
Each tuner has their preferred method of receiving information from you when remote tuning so make sure you have this preference in mind when sharing the logs with your tuner. Also please bear in mind tuners do get busy so it may take some time for your tuner to review your log files and make any amendments. To send a log file to a tuner, go to the "my files" data log folder and select the desired log, add any comments you may need to and then share using a 3rd party app.
The tuner will receive the file and can then analyse it with ProECU or other analysis software. You can view these logs using any .csv compatible log file display and analysis software, for example tuner assist or Mega log viewer or even other manufacturers software i.e. AEM or adaptronic log viewer. However not all software can handle the header data stored in the file so may need to be edited on excel or text format first.
Clearing and Sharing DTCS
To Check, Display and Clear DTC’s that may appear when tuning a vehicle simply go to the DTC option in the mode page and view the current dtc’s.
If you intend to send DTC reports to your tuner as much detail as possible should be included with the report, if possible a log file of the car when the DTC actually occurs will be very helpful for the tuner when trying to diagnose the issue. The other important item is the actual DTC code if it has been captured by ECU connect. Sending DTC reports is done similarly to sending logs, simply go to the archive menu and select DTC reports
The tuner can review files and DTC reports, keep in mind that this is not a quick or easy process so it may take some time to come up with any updates and may even require further information to be gathered, testing performed, modifications made and sometimes further costs.
Hopefully this information will help you to get logs to your tuner directly from ECU connect improving not only communication and speed but the quality of logs and reports as well. If you have any further questions please email email@example.com.
