Having issues with various cars with 675dk11sp software. I understand sp is special and is most likely for canada redundancy. Is there any newer or better versions of clc canadian software? Having 003-002, selector lockups, some canadian redundancy faults. Have done resistor loading, power supply checks and all board changeouts and bulletins, newer eepromm burnt etc. Cars will run for 3 or 4 months and no issue. Then they will sprout up with faults again a week or 2 apart and then stop for a month or 2. Wondering about isolation transformers and building grounding as well if that would help. Any help would be great. Thx
