Help with logging oil pressure

[Harrismarine]

Can someone step me through setting up the pid to log oil pressure. LS1 411 computer.
I have searched and am still confused:help2:

Thanks Mike

Hi Mike,

See this post (http://forum.efilive.com/showthread.php?14605-Oil-pressure-PID&p=131754&viewfull=1#post131754) of mine from a while ago. I suspect you aren't running the latest software version as this was released as an update ;)

Cheers,

Thanks Andrew, Done that. I still have no pid for pressure, I am missing something..

[Tordne]

The PID just reports a raw voltage from the sensor. If you wanted it to be represented as a kPA measure (or other unit) you'll need to create a CALC PID.

I can't find the detail at the moment but I know it was something like; there used to be a kPa PID in the software which we used to calculate internally given a known voltage on the LS1 controller. As there are now many more controllers the actual PID is a voltage PID and the scaling is different between controllers and sensors. For that reason the EFILive software now provides the ID as the sensor voltage as output by the ECM.

I have GM.EOPS and CALC.EOPS but both are in voltage:damnit1:

take a look here. http://forum.efilive.com/showthread.php?14605-Oil-pressure-PID&highlight=oil+pressure+pid

OK, I have got as far as getting the pid. When I right click on it there is no info but when I right click on the engine oil pressure sensor voltage it gives me this.

Expression
V=Raw({GM.EOPS})/51
is NOT valid because:
Unknown parameter{GM.EOPS},at position 14.

PID value cannot be determined because
the following error would occur:
Expression not valid: Unknown parameter {GM.EOPS}, at position 14

Mike, what is your V7 software build version (do Help->About)...?

GM.EOPS was incorrectly spelled as GM.EOP in earlier builds of V7.

[Harrismarine]

V7.5.6 build117, I did add the S as per instructions. Thanks for the help its anoying me now

Mike, can you post your calc.pids txt file so we can check for typo's.
Cheers Mick

Thanks Mick. This is Calc_pids.txt.

Mike,

Use the calc_pids.txt file in post #11...

copy it to the folder My Documents\EFILive\V7.5\User Configuration (overwriting the existing file there).



Make sure there are at least 2 blank lines at the end of the calc_pids.txt file.

[Harrismarine]

Thats the one that is already in there, Should i deleat the one in post 12

[Tordne]

Just emailed you the file from my system to copy to your machine.

[5.7ute]

Mike, you only want the one file in that folder named calc.pids. I usually change any other to something like calc.pids2. (I hate deleting files just in case lol)
