Summary of change:
Dear Vems, You provided pictures and great explanations to add 2 analog inputs thanks for that. But I saw that I already have 2 existing green wires on my 3B board that share one extremity of your 2 red drawn on the board. http://www.vems.hu/files/lolo_quattro_config_file_for_3B_conversion/vems_vue_dessous_2_existing_wires.jpg What shall I do with these wires? I also have light green and orange wires at the position of your proposal for a analog ch2 and ch5. I have added in colours on your picture the existing wires (black, light blue, blue, grey, orange, red) http://www.vems.hu/files/lolo_quattro_config_file_for_3B_conversion/v3Bottom_with_vems_recommendations_and_lolo_existing_wires.png that are going from the board to the existing sc6 connector. http://www.vems.hu/files/lolo_quattro_config_file_for_3B_conversion/vue_dessus_existing_wires_going_to_the_sc6_connector.jpg Maybe I do not have to do any modification on the board ? Are the existing wires (black, light blue, blue, grey, orange, red) input already available from factory ? output ? pull up ?, protected ? which channel ? * Can you check the paper that came with your ECU ? That is the best source, as your device might be different from default if ordered with special specs ** especially for 3B with SSC6 which has different best set of pins depending on circumstances ** especially that this very controller was modified later, AFAIK * if the paper was lost, you can also test easily. Take a 1kOhm resistor and pull the pin in question (from SSC6) to GND, than to +3..5V. Watch the "analog inputs raw" gauge-group during this. ** that is safe to any pin of the extra connector SSC6 (or econoseal10 in newer devices) even if it's not analog input. Just do not apply more than 5V ( >5V would be damaging even through a resistor) --------Explanation from VEMS to add 2 analog input------ '''Getting extra analogs''' Do these to get 2 pcs. of 0-5V analog inputs. *solder 2 wires to the bottom of the board like on this image: ** http://www.vems.hu/files/LoloQuattrobadcoldlogfile/v3Bottom.PNG *Remove the two resistor marked cyan and solder two 10kOhm resistor marked black on this image: ** http://www.vems.hu/files/LoloQuattrobadcoldlogfile/v3Top.PNG **The two resistors are the pullup resistors to the two analog input, so if remove them, the analog inputs are become only protected. *wire EC18 pin 2 and pin 3, this way you can use analog in ch2 and ch5
