2016 ZO6 scanner incorrect MAP readings

[veee8]

Just a heads up, I just tuned a 2016 ZO6 yesterday, and with both 2.24 and 2.25 scanner, the map would read 65 kpa key on engine off. It is off the entire time its running as well. I confirmed with GM MDI that it reads correctly with their system, just not reporting right in VCM scanner. 2015 ZO6 reads correctly, but not the 2016
.

I just checked the vehicle with a simple hand held scanner, and it shows the same 65kpa key on engine off. So that means there is something skewing the data output on anything other then GM's tools.

I see the same on my 16 Z06

[Keith@HPTuners]

When you used the GM MDI, are you looking at the SAE parameter, or a manufacturer specific param?

I'm pretty sure anything with the MDI is specific to GM. The tech said he just started scanning like usual, just changed it to metric to read kpa.

Seeing the same thing on a 16 Z06 today. However I do see there is a MAP Hi-Res and a MAP Hi-Res (SAE). The SAE pid doesn't work and kills some other PID's when used. The regular MAP Hi-Res does work and seems to read correctly.

This seems to be a GM bug for this OS. Several customers have verified the erroneous readings with different scan tools.

Got another one in here, I changed the list and chart settings to the MAP HiRes and it does seem to work ok and is accurate.
