Using EFILive (V5/V6) to capture Wide band O2 data

I'm using my analog output voltage to go into my a/c pressure sensor with V6.

Your right my afr=v*1.6+10

Thanks

So you're not using a FlashScan interface, and you are trying to hook your wide band via the A/C pressure sensor?

or would it be easier for me to convert the voltage in the a/c voltage pid, v*1.6+10 and log that?

thats correct

Oh, I misunderstood your requirements - sorry.

Use this calculated PIDs file:
Note: There is no need to define the units V and AFR because they are already defined in the Program files\EFILive\V7\Configuration\sae_generic.txt file.

Code:

# ============================================================================== # File details # ------------ # # This section defines various details about the file format. *FILE #Parameter Value Description #---------- ---------------- --------------------------------------------------- VERSION 7.1.1 File version DECSEP . Decimal separator used in this file # ============================================================================== # Units # ------------------- # See sae_generic.txt for more information on the *UNITS section *UNITS #Code System Abbr Description #-------- ---------- -------- -------------------------------------------------- # ============================================================================== # Add slot definitions here # -------------------------------- # See sae_generic.txt for more information on "SLOT" formats # #Units Low High Fmt Expression #------------ ------------- ------------- ---- --------------------------------- *CLC-00-001 V 0.0 5.00 .1 "{GM.ACPS}" AFR 10.0 18.0 .2 "{GM.ACPS}*1.6+10" # ============================================================================== *PRN - Parameter Reference Numbers # -------------------------------- # See sae_generic.txt for more information on the *PRN section # #Code PRN SLOT Units System Description #------------------------- ---- ------------ ---------------- ---------------- --------------------------------- CALC.AFR F001 CLC-00-001 "AFR,V" Fuel "Wide band AFR"

(Edited to correct {GM.ACP} to {GM.ACPS} as per LS1Nova's post further down)

I copied that formula and I get an error code when I open efilive now.

err_cinfig/92
units afr not found

and I can't connect now due to this error

err_noinit/121
not initialised, call obiil nit()first

Got this fixed, I just ereased all the afr's in the formula. but it ends up giving me a number in the 350 range for 14.7 when I log.

Make sure you are using the latest version of EFILive - I strongly recommend upgrading to V7.2.2 if you have not already done so. It's free - even if you are still using an AutoTap interface.

Meanwhile you can add the AFR units to your calc_pids.txt file like this:

Code:

# ============================================================================== # Units # ------------------- # See sae_generic.txt for more information on the *UNITS section *UNITS #Code System Abbr Description #-------- ---------- -------- ------------------------------------------------------------- #Fuel #---------- AFR None AFR "Air Fuel Ratio" # ============================================================================== # Add slot definitions here

Thsnks for all the help Blacky. :D

I ended up figuring it out, here's what I used. It just seemed more simple to me.

# Calculated
# ----------------
#Units Low High Fmt Expression
#------------ ------------- ------------- ---- ---------------------------------
*CLC-00-001
V 10.0 18.0 .1 "({GM.ACPS}*1.6+10)"

# ================================================== ============================
*PRN - Parameter Reference Numbers
# --------------------------------
# See sae_generic.txt for more information on the *PRN section
#
#Code PRN SLOT Units System Description
#------------------------- ---- ------------ ---------------- ---------------- ---------------------------------
CALC.AFR F001 CLC-00-001 "V" Fuel "Wide band AFR"

Good idea, I forgot about {GM.ACPS} (the sensor voltage).
However, that will show up with units of "V".
You can make the units show up as AFR by adding them as I showed a few posts ago. Then just change BOTH V's to AFR.

Paul

So the correct calc_pids.txt file should look like this:

WARNING - check that the units AFR do not exist in the file:
Program Files\EFILive\V7\configuration\sae_generic.txt
If that file already contains the AFR units definition then do not include the AFR units definition in calc_pids.txt
