Does the correct pO2 show on the Shearwater download software (i.e. the 
Shearwater Desktop)?. This means that the data are correctly reported, 
not a default calibration value as currently with Subsurface.

If this is the case, then the problem should in principle be solvable 
and it possibly means that the coding in the dive log is slightly 
different from that of the standard Petrel and the Fischer Petrel 2. The 
most knowledgeable person to approach is Jef Driesen but he would need 
some specific information from your download. A first approach is to 
inspect the .bin dumpfile generated for debug in Subsurface. Then use 
his dctool executable (If I remember correctly it can do Bluetooth and 
it is extremely flexible) and see if you can trace the pO2 values.

I am not sure this is what you may want to hear, but assume that (if you 
want the problem solved) you need to take the initiative. You may 
possibly be the only person in this circle which has a divecan Petrel so 
you are in the best position to address the problem.

Kind regards,
