This may be applicable to a lot of ECM/PCM's but I'm only interested in the P01 (0411) PCM. I have virtually no circuitry knowledge so if I'm crazy just say so. How difficult would it be to add non-volatile memory to store the data that is lost when the PCM is powered off? I'm sure there would be some OS programming involved as well. Wasn't sure if this had been addressed before so I thought I'd throw it out there for discussion. Thanks. -Bob
