EDL-1 data logging

I plan to use the EDL-1 with ECU Black to collect engine data during track sessions. Some questions:

  • Does the EDL create a new log file every time power is cycled?
  • Is the SD card the only way to move logged data to a PC (as opposed to connecting the PC to the EMU Black, using the Bluetooth…)?
  • The available Bluetooth apps all appear to be dash displays showing only live data - is there a BT app that can show logged data and/or make changes to EMU settings?

Yes, EDL-1 creates a new log every time you start the engine and creates folders with the date and saves the log for each date. And this is the only way to have data without traveling with a laptop.
EDL-1 works, as you can see, in connections via RS232 only in one direction, just like its Bluetooth module (RX only), which means you can view the parameters without modifying them.


Thank you for your excellent reply, Krzysztof.

Additional questions: the wiring diagram shows connections to +5VDC and sensor ground, but the specs show power supply can be 5-20 VDC. Is it permissible to wire to +12VDC and chassis ground?

Yes, it should work, there is probably some kind of voltage stabilizer or converter inside that powers the entire electronics with +5v.

I hope you don’t mind me asking this question in your thread. It’s kinda related.

I’m learning to program microcontrollers and one of the project I want to make is my own data gauge. I want to start by simply displaying the data passed to the EDL onto a small oled screen. Is the serial data format available in a file, which I can then use in my program? How about the CAN data that the EMU output? Thanks.

Can data is defined in the V2 software in the help file section for CAN parameters.

Personally I think CAN would be the better route for a new project. What your describing has been done and produced many times now, so it’s a well travelled path.
