I'm pretty sure you can read the info from the M1000, question is, did you install MBM and do you have it running when you tested the above ?? Can you read the propper values from within MBM ?
The Temperature Kit would allow you to read any 4 temperatures you want (I have inside and outside of the car). There's also a Voltimiter Project by Mauri that allows you to read the Battery voltage (I also have that), they all work fine, but may require some skills in Electronics ..
