I received your OBD-Emulator MK2 this week. This is a very nice tool Unfortunately I experienced a problem when setting more than one DTC-code. Although the GUI confirms that more than one code is set simultanously, I do only get one DTC-code when checking with an OBD-tool. This is a function that I urgently need for my development work.
For example after setting 3 different DTCs the GUI confirms with "Totally 3 DTCs has been set". But when checking with a fault code reader only the last DTC ist set.
When checking with a CAN-tool my request is: ($7df) $01 $03 The reply then is: ($7e8) $04 $43 $01 $03 $00 Fault codes 0100, 0200 and 0300 should be set.
