Oil pressure PID

On the PIDs tab, locate and select the pids GM.EOPS and CALC.OIL_PRESSURE;

to help in locating those pids, click on the column heading "Caption" (i.e. on the heading itself), this sorts the pid list alphabetically on this column (but in reverse order Z-A)... click on it again to un-reverse the order A-Z... look down this column for EOPS and OIL_PRESSURE;

if you can't find them, uncheck the Selected box at the upper left.

OK I've got those selected, now what?

You have to add that Calculated PID to the 'calc_pid.txt' file or rename the file in the above post to 'calc_pid.txt'.

Ah, good point, I don't know what I was/wasn't thinking.

Ok I have renamed the file to calc_pid.txt. when I click on the pid its not valid. Any idea what I am doing wrong? Thanks for being patient.

Rightclick on the pid to see what other pids it requires... the other pid is GM.EOPS, you have to select this also (does your vehicle support this pid?).

No worries.

I am working on a 2005 tahoe drivetrain. I was able to view oil pressure sensor voltageEngine Oil Pressure Sensor Voltage . If you select both pids at the same time the calculated oil pressure becomes valid? When I right click to see whats required I get
{CALC.EOPS}

Expression:
V = Raw({GM.EOP})/51
is NOT valid because:
Unknown parameter {GM.EOP}, at position 13.

PID value cannot be determined because
the following error would occur:
Expression not valid: Unknown parameter {GM.EOP}, at position 13.

Hmmm... I get the same thing.

GM.EOP should still be a valid for the LS1A/LS1B PCM's, even when it's not wired to the PCM.

I pm'd Tech Support.

I don't know if you have a typo in the post or in your calc_pid file, but its suppose to be GM.EOPS.

There's CALC.EOPS and GM.EOPS is missing... and CALC.EOPS mentions GM.EOP.... and GM.EOP is unknown.

So something is messed up.
