Weird issue /w P2000
First let me just say everything was working 100% earlier. Sensors and everything were working correctly in ECU Manager. Now I get this in ECU manager...
ECU still seems to be functioning as far as I can tell. Fuel pump primes etc. If I unplug the map sensor, the MAP reading in ECU Manager starts flashing but number does not change. It's almost as if the values are frozen. Also, while unplugging/connecting the map sensor I hear the boost solenoid click. No idea what that could mean.
I've tried upgrading the firmware to latest version and reuploading the map with no success. Although the values in ECU manager for sensors have on ocassion changed with the above procedures. The Coolant sensor was reading 19*C before and now it reads -273*C for example.
One thing to note is I turned the car power on with the ECU (chassis) ground disconnected as I wanted to look at map at the time. Could have doing this somehow damaged the ECU? Even without its ground, it still powered on and was working. I realized the ground was unplugged when all the sensors weren't working and then plugged it in but didn't help. This was the first time I noticed the problem.
I'm now sure if the car starts anymore as I have the UIM off to clean and loom the harness.

I think I'm suffering from, finding problems that don't exist syndrome. I either fixed it somehow or attempting an all nighter after a full day of working on the car by chugging coffee and coke isn't a good idea...
