• Event marking feature – pressing the rotary knob inserts a marker into the datalog
• Easy firmware updates via usb-B cable and drag & drop

LDperformance CAN Data Logger also features 3.2″ OLED display, which can show all logged parameters grouped in different pages. You can scroll through them by turning the knob. Every page can be easily modified by pressing on a chosen parameter and picking another. There are different layouts to choose from. Each parameter’s decimal position or offset/range can be modified by editing the corresponding canx file.

Compatibility

LDperformance CAN Data Logger is compatible with all CAN bus devices, including:

• Throttle & pedal positions from LDperformance Throttle controller
• Output states and current for 8 channels of the LDperformance PDM
• Oil pressure, temperature, EGT, GPS speed from LDperformance DASH2
• All data from your aftermarket ECU
• Any other CAN device if you have a canx file explaining the CAN IDs

Pinout

Quick start

1. Connect 12v and ground to power the device.
2. Connect CANH and CANL wires to the other CAN devices.
3. Put the SD card in a computer and copy the canx file for the
4. CAN device you want to add to the canx folder on the sdcard.
5. Insert the card in the datalogger and turn on.
6. It will load all canx files one after the other and restart.

Screen configurations & layout

Rotating the knob will scroll through the different parameters and screen presets. You can choose between having many parameters in small font or a few in large font or a mix of both.

To change a parameter press on it briefly and turn clockwise to pick another one in its place. It’s also possible to pick an empty parameter to create more free space.  To move a parameters location to the left or right, press and hold and move left or right at the same time. 

How to add another device for logging

All LDperformance devices already have canx file describing the CAN protocol. So if you want to add all data from Dash2, simply place the dash2.canx file in the canx folder on the sdcard. On next power up the datalogger will load the file and start logging every parameter described in the file. If the file doesn’t load, it is because it is too big. Edit the file removing useless comments or information or separate it in two files.

Find out more details in the LDperformance CAN Data Logger Manual.

What happens if time is lost?

If the CAN Data Logger is switched off for a long period (months) it might forget the time. On next power up it will prompt the user to set the time. Even if not set it will still log data but the filename will not contain the time.

To recharge the battery keep the car running for some time or alternatively keep the device plugged in the USB overnight.

Restore defaults/set CAN speed

• Press and hold the knob and turn on the device.
• Choose between configuring time, can speed or restoring default settings.
