Custom PID's...Created by Users

[S2H]

I thought it would be nice to start a thread of Custom PID's..created by Users

If you are using something and would like to share..please feel free to post...
if I get enough of them I'll make a sticky....

I'll start with...

[S2H]

MPG - Requires: MPH - Injector Flow Rate - InjectorPulse Width - RPM - IAT - ECT and 8 Cylinders - works on LS1's for sure
[SENS.20]/(([PID.6210]*0.132276)*[SENS.112]*[SENS.70]*8/(6175*(((([SENS.11]+[sens.10])/2)+273.15)/299.8167)))

Boost Amount - Requires: MAP
[SENS.30.IMP]-14.503773773020923

LTFT+STFT - Requires: LTFT - STFT
[SENS.114]+[SENS.116]

EQ Ratio to Commanded AFR - Requires: EQ Ratio
14.7/[PID.6010]

RAF In Gear - Requires: Idle Adapt(STIT) - LTIT Gear/AC Off
[PID.2240]+[PID.2229]

RAF Park/Neutral - Requires: Idle Adapt(STIT) - LTIT PN/AC off
[PID.2240]+[PID.2231]

Gee I'm a neebie, LOL!

So for 6 cylinders, is this correct?

[SENS.20]/(([PID.6210]*0.132276)*[SENS.112]*[SENS.70]*6/(6175*(((([SENS.11]+[sens.10])/2)+273.15)/299.8167)))

I dont know if it works on 6cyl or not...but that is part that would have to change for 6 cylinder..some of the sensors would have to be double checked...I dont know what the 6cyl guys are doing..somebody around here made it work for them....

Is there a link on how to setup custom PIDs? I have the table display open, I right click on a blank cell, then double click on configure user defined and then I get a window but now what, I can't save it, do I need the MVP plugged in? I'm confused. Thanks

theres no save button...
just close it out when you are done..

I also find that I usually have to close the scanner and re open it..I dont know why..I'll address it in our moderator section

I got it to work, same way as you described it, I have to close the scanner and reopen it for it to be available. Thank you.

its actually a known bug to our mods and other staff....posted in our bug report for the latest build...its being worked on

ok..with that aside..anybody else have any useful custom PID's that you are using??

even if they might be vehicle specific??

Scott,

I'm planning on trying to do 2 for the LS2..

IFR is not a supported PID for the LS2. I am thinking there is a way to create one, I just need to figure out the math Utilizing:
32lb injector
Injector duty cycle
Ambient air temp (Engine>Airflow>Ambient Air Temp)

One would think a IFR could be created.


Since IFR is not a valid PID your MPG PID does not work. I was going to try and figure out how to get that going once my IFR PID was up and running.


My biggest thing right now is I am not sure how to figure LB's minute based on injector pulse width. Any help in this area would be great.

[S2H]

injector sizing is
=IFR*SQRT((Rail pressure+Vackpa*KPA)/RatedtPSI)

Injector Pulse Width is
IPW=120*Dynamic Airflow/(Cyl*RPM*commanded AFR*IFR)

do some math and you can turn that last formula into IFR
so IFR=120*Dynamic Airflow/IPW*(cyl*rpm*commanded afr)

maybe???
120*[pid.2320]/[sens.112]*(8*[sens.70]*[sens.121])
this would be ls1...just need to do some unit converion yet possibly
possibly a few different pid #'s on other vehicles

this is all rough just from formulas I found using google

I have no way to test this right now..LOL

[Super73]

Scott, please do me a favor and do not abbreviate I'm just learning the scanner side of things Now I got to figure out what most of that is.. Or if you do, say what it is first.. Thanks a ton

So I am assuming IPW is injector under sensor not [PID.6200] or [PID.6201]

The function string you posted seems to be what I come up with as well again assuming you are refering to sensor 112 for IPW



PID.6210 is IFR for LS1's it seems. This does not exist in the LS2 world (at least on the 07 TBSS I have). So with:
120*[pid.2320]/[sens.112]*(8*[sens.70]*[sens.121]) as IFR

[SENS.20]/(([PID.9005]*0.132276)*[SENS.112]*[SENS.70]*8/(6175*(((([SENS.11]+[sens.10])/2)+273.15)/299.8167))) would be the new MPG PID (9005 is in red because it may show up as 9004 through 9010, you will have to find it).. This is not verified due to the Fiance being out

IFR = Injector Flow Rate
IPW = Injector Pulse Width
Cyl = Cylinder
AFR = Air Fuel Ratio
RPM = Revolutions Pre Minute
SQRT = Square Route
IAT = Intake Air Temperature
ECT = Engine Coolant Temperature
MAP = Manifold Absolute Pressure
kPa = KiloPascals
PSI = Pounds per square inch
vac = vacuum
LTFT = Long Term Fuel Trims
STFT = Short Term Fuel Trims
LTIT = Long Term Idle Trims
STIT = Short Term Idle Trims
IMP = Imperial
MET = Metric
MPG = Miles Per Gallon
RAF = Running Air Flow

that should be all my abbreviations..LOL

[Super73]

Thanks Scott.. I'll let you know how the custom PIDS for IFR and MPG work once I get the TBSS back (Wed time frame)..

I might be able to test it sooner with a rental car on my trip to canada I am taking

[S2H]

so I mised a pair of () in there for sure
120*[pid.2320]/([sens.112]*(8*[sens.70]*[sens.121]))

and I still need to figure out unit conversion
pid.2320 is lbs/minute
sens.112 is in milliseconds..so we need /1000 times 6 or times 0.006 for per minute
sens.70 is in revolutions per minute
sens.121 is afr
IFR is lbs/HR. so times 10 making 120 = 1200
I know I'm missing a lot on this one somewhere..LOL

convert all from per minute to per hour


(120*([pid.2320]*60))/(([sens.112]*0.036)*(8*([sens.70]*60)*[sens.121]))
??? maybe??
need some more help from somebody with more knowledge....LOL

[Super73]

Can't get IFR nor MPG working

http://73-ls1.com/New3.cfg

[Super73]

Anyone have some input?

[S2H]

I playe with it the other day...the rental car I got is a hyaundi...so I cant even begin to try..LOL

I know its just a formula issue...maybe in units conversion...
I just havent had any time to try to figure it all out...
we've been working way too many hours and crunching a lot of #'s here and I just dont want to do any math at the end of tehday..so I havent even looked at it here while I'm in canada....

[xonelith]

I've been workin in your formulae for my V6. Been able to get most things to work (need to check the actual numbers). Not havin any luck with the mpg though. Seems I have an unsupported parameter, but when I scan each individual PID.* or USER.* or SENS.* they are ok..... when I have some time, I'll post what I have to supplement Soundengineer's work... I made a lot of assumptions though
