## TL,DR
With all the electromagnetic interference around the gasoline engine due to sparking CAN physical layer provides the level of reliability above RS232 and USB physical layers.

There is no standard way of communicating with CAN bus on Windows. At the moment rusEFI is focusing on [PCAN by Peak System]([https://www.peak-system.com/](https://www.peak-system.com/)) and ELM327 options of the Windows side of CAN.

## PCAN
# PCAN
Between three major professional CAN frontend vendors we like PCAN by [https://www.peak-system.com/](https://www.peak-system.com/) due to the combination of the following

rusEFI bridge between PCAN and ISO-TP is located at [https://github.com/rusefi/rusefi/tree/master/java_console/io/src/main/java/com/rusefi/io/stream](https://github.com/rusefi/rusefi/tree/master/java_console/io/src/main/java/com/rusefi/io/stream)
# ELM327
## ELM327
With more than a dozen magic commands it's possible to switch ELM327 device into binary transition with serial communication between calibration software and ELM327 acting as a bridge. At the moment we have a very odd bug making the overall solution not working as of Jan 2022.
See [https://canhacker.com/ch-obd-m02/](https://canhacker.com/ch-obd-m02/) for great pinout image. Yes both GND are needed for reliable ELM327 operation.
