OBDII ElmScan source code for the ELM327

[ClydeCrashKop]

Years ago ELM327 was open source. Just because the open source ElmScan source code for the ELM327 isn’t available on line and I have it, here it is. The output was text strings. They weren't obvious but you could sort it out if really motivated. The needed alld42.dll is in the zip folder, put it in C:\windows\system32.

This topic comes up occasionally.
Can the can output an automotive computer be read with a scope?
