Flashpro not reading knock count or MAP correctly

Hello I recently reset my 07 TSX AT to stock using flashpro (was previously turbocharged) and now when I ran a datalog to make sure the car was running fine on the stock tune I noticed that there were some strange sensor readings. For example the honda MAP sensor (which I have not messed with whatsoever because it was a low boost setup) reads psi all over the place during WOT the psi is consistently over 100PSI. However A/F ratios appear to be good. And as soon as the datalog starts the knock counts read as follows: cylinder #1 - 31, cylinder #2 - 19200, cylinder #3 - 31, cylinder #4 - 19200. These are constant and do not reset when car is turned off and a new datalog is started. Also, prior to ECU reflash both these sensors were working perfectly, it should also be noted that I am up at about 5000 ft elevation so atmospheric pressure is lower then at sealevel. Any help would be appreciated as I am at a loss for words. most recent datalog is attached below. (also car has a cold air intake and is de-catted).

If you returned the ECU to stock then not all sensors will datalog correctly, as the stock ECU doesn't supply that information.
