Data logging 04 duramax

[nezz48]

The actual fuel pressure pid has disappeared. Have reinstalled app and reset tool.

[mikel]

what changed?
what device are you using?
did you update the tool or DV?

[nezz48]

Updated data viewer.. have tried multiple older versions and still not showing as an avalable pid.

[nezz48]

Pid was still there after update bus was not reading correctly. Retrived vehicle info again and it disappeared

[mikel]

try clicking display infrequently used pids in dataviewer.

[nezz48]

mike it has to do with the vehicle update revision 2r01w. i installed an earlier version 2r01u and everything is back to normal. might want to have your guys check it. i also was missing the pid folder "intake"

[nezz48]

reverified. resinstalled the newest version for vehicle. got intake folder back but still no actual fuel pressure in the diesel folder.

[nezz48]

And now I can't get the pid back after I reinstalled the older version

[mikel]

the vehicle app shouldnt have any effect on what PIDs are displayed in Dataviewer at all.
We are looking into this.

[nezz48]

Never been able to read diag codes either

[mikel]

can you post one of th elogs that had the pressure pid and specify for me which pid it is by name?

[nezz48]

actual rail pressure is the pid that goes missing.

[mikel]

and are you logging directly to the device or streaming to DV on a PC?

[nezz48]

Directly to dv. Didn't seem to datalog on device alone.
