Has anyone installed a real time passive eng data logger such as the snEEC-IV or similar to monitor EFI/PCM functions while your MH is in operations.? snEEC-IV is sold by Race Systems but there...
The items I suggested are not really what you're looking for then. I suggested a couple options for dataloggers. You don't want to datalog, you want to monitor. I don't know of anything like that compatible with EEC-IV (what you have).
