I would like to upgrade to the 2 bar OS offered for the 97-98 PCM so I will have access to a full VE table and both timing tables, but would like to keep my stock 1 bar sensor. I have the PCM "tricked" into SD now but only have access to the secondary VE this way.
I assume it will work without any changes and only read the values of the VE up to 105 KPA with the 1 bar sensor, but I have never actually looked at the 2 bar OS so I am not sure if that will shrink the resolution of my usable VE back down to half size (like the secondary VE I am using now).
So my question is, What changes to the software are required to make the 1 bar sensor work properly with the 2 bar OS? If the 1 bar sensor will work without any changes, what will my VE resolution be like?
I read somewhere to change Map Linear=94.43 and Map Offset=10.33 in the engine diagnostics section to make the 1 Bar work properly, but no one has confirmed this and I honestly am not sure exactly what it means.
Thanks in advance for any help

Also, I have 0411 PCM I have considered swapping in, but I will have to purchase 6 credits to do so. Is there any substantial reason to spend the extra money on converting over to the 0411 over the 2 bar OS for the 97 PCM?
