LNF Custom PIDs

[CDNITE]

So I know there are many many ways to monitor changes we make:

Change in speed over time, 60-100mph

Change in RPM over time, 2k-6k

VE and MAF

What if we had a estimated power PID in HP, Watts, torque whatever, that way in all my logs Im always comparing the same real world effects in a graph on the scanner?

How would I make a custom custom PID to do this?

Where do I find the standard PIDs and their code/identifier, are they in a list? Edit: Can be found in the HPT Custom Function, Filter and Trigger Help Window

Also if yall have any custom PIDs you'd wanna share please do so... we're all interested!!

I looked into setting up a torque pid but got lost doing something else. Im not sure if it can be done but the factory RPD does give you a torque reading. Im not sure how close it is to real numbers but there might be something to it if you could figure out where to access it. Ive just always used the old timer to judge my experiments.

Here are some I found in other posts. I'm still trying to find the list of PID codes/numbers.


PID for AFR = Lambda * fuel stoich. ([PID.6061] X 14.68)
Most fuel is 10% ethanol now so stoich is a bit lower at 14.13 if that's the case.

PID to add the LTFT's to the STFT's. ([PID.6]+[PID.7]

PID to find WOT MAP = Baro - Atmospheric pressure. ([PID.2338.PSI]-[PID.51.PSI])

PID for Boost. ([PID.2339]*9.369)-([PID.2340]/6.895)-.53

PID for Intake Cam position compensated. ([PID.2172]-10)*(-1)
PID for Exhaust Cam position compensated. ([PID.2178]-6)

PID for Cam over lap. [PID.2172] - [PID.2178]

[cobaltssoverbooster]

i belive the intake cam would actually be [PID.2172]+10 to get compensated position. no need for the extra (-1)
and the cam overlap pid made by subtracting the two is a definite pile of shiiish that gmtech and i have found doesnt show us anything helpful.
we thought it did in the early developements but its turning out to be not so helpful now.


Factory Wideband AFR Error
[PID.6005]-[PID.6160]

all the donated pids that show up should be added to the first post for ease of access

[cobaltssoverbooster]

lnf engine torque pid we found early on in i believe 2009 that the value was a calculated representation. it would be nice to see how it scales compared to a true dynomometer. nice finds

[stromboli86]

i belive the intake cam would actually be [PID.2172]+10 to get compensated position. no need for the extra (-1)

i added the -1 to this PID so that what the scanner reads/shows is exactly what you input into the tables when adjusting cam timing. Its actually pretty cool when you watch the way the 2 lines interact(5th series in scanner)!! The further apart they are, the more overlap i believe

[cobaltssoverbooster]

i see now, and i like... wait for my custom excel program you might be able to use it in conjunction with that histo.

[|V3nom|]

good stuff here.

CDNITE maybe you should delete the redundant posts so everything isnt repeated.

[|V3nom|]

is the boost pid no longer working?

PID for Boost. ([PID.2339]*9.369)-([PID.2340]/6.895)-.53

tried it out in my graph but never read anything.

[|V3nom|]

also cant do calculated HP due to not having [SENS.108].

[|V3nom|]

for reading fuel rail pressure in the chart, do you use a sensor or pid? i tried the sensor but it didnt read anything, this was for commanded and actual.

[|V3nom|]

correction, i tried the pid for fuel rail pressure commanded and actual but couldnt get it to show on the scanner chart. is there another pid or something im missing?

[|V3nom|]

quick question. can you only display in the charts what you have set up in the table display? i havent tested it yet but if so this is the reason i cant view fuel pressure.

[shabby]

can you only display in the charts what you have set up in the table display?

Yes, it has to be in the table display.

[cobaltssoverbooster]

Was noted in videos as well iirc lol

[|V3nom|]

lol yeah i remembered that after i made the post. oh well.

[cobaltssoverbooster]

happens to everyone

[Freakotec]

Anyone having issues with logging their low res boost pid with 3bar maps? I just installed a set tonight and now i can't seem to get the ([PID.2338.PSI]-[PID.51.PSI]) to work any longer (and yes I updated my tune to work with the new maps btw.... lol). Do I need to change the function to something different now with using the different maps, or is it just something that's no longer able to be read?
