What pid to monitor fuel pressure?

[DrkPhx]

Hi,
I'm looking to monitor fuel pressure and injector delta, but I can't find the pid to monitor fuel pressure. This is for a 13 E67. Anyone know?

Does your 2013 vehicle have a rail pressure sensor...? (which vehicle is it...?)

possibly GM.FRP (in Volts)(it would then need a calc pid to convert to psi)(I wasn't aware that GM installed these)...

or possibly GM.FRP or GM.FRP_A but I don't think these are it (appear to be for Diesels).



E67.INJPDELTA_DMA

E67.INJPDELTA_DMA maybe not have been defined on the later OS's, 'DMA' PID's are OS specific and take a lot of time to define so it may not have been done.

Thanks for the quick replies guys. It's actually for the LSA applications; ZL1 and CTS-V. I believe the fuel pressure is measured in the fuel pump on these cars, but I'm not entirely sure. I've tried the different fuel pressure pids with no luck.
