Logging FPR through EGR.

I followed the instructions to log FPR through my egr on my LS1B (05 silverado) I have adjusted the calc.pids as shown in the tutorial. I just save the file back in the same folder with the same name correct? Does it look right? Thanks for your time.

Yes, save the file in the same folder.


BUT: your file as you posted above is not complete... after the last line ("# Code PRN SLOT Units System") you should have a line like this:

CALC.FPR F001 CLC-00-001 PSI Fueling "Fuel Rail Pressure"



BTW: psi (lower case) is already defined, so you can skip defining PSI, and just use psi (lower case).


NOTE: after the CALC.FPR line, you should leave at least 2 blank lines (i.e. hit ENTER twice) before saving the file.


ALSO: .1 precision is maybe more suitable than .2 (e.g. 58.0 psi vs 58.00 psi).


ALSO: do you want FPR in kPa...?

If you want FPR in kPa also...



*CLC-00-001
psi 0.0 100.0 .1 "{GM.EGRS}*25-12.5"
kPa 0.0 700.0 .1 "{CALC.FPR.psi}*6.895"

. . .


CALC.FPR F001 CLC-00-001 "psi,kPa" Fueling "Fuel Rail Pressure"

Thank you. I tried to avoid asking simple questions on the forum but i'm trying my best to learn everything. I've spent hours reading through this forum trying to learn. I don't really need to read kpa, PSI should be ok. Just want to make sure fuel pressure rises along with the boost.

Feel free to ask (if you don't understand something, it's always better to ask).





Please make sure you have at least two blank lines at the end of your calc_pids.txt file.

Also, do this:

remove the FPR manifold-reference hose, and measure rail pressure... this is your base pressure.

( and then remember to reconnect the manifold reference hose )
