Curious?
what is the voltage at the battery at idle to full load?
The first thing I check on live data read is the voltage,what I want to see is 13.5 plus or minus .5v
I have seen these run at over 16V and as many sensors rely on 5V feed and the reading less than that over voltage can screw up readings.
simple test.
