Datalogging WBO2 and Datamaster?
Here's the situation:
1. I am using the WB hac that Z69 came up with (https://www.thirdgen.org/forums/diy-...-released.html)
2. I am also forced to use Datamaster (v3.4.1) b/c I have a Corvette with the 7727 ECM.
3. I have the output of my LC-1 plugged in to the MAP(2) intput in the 7727 ECM.
4. I cannot find the 'calculated AFR' anywhere on the datamaster program. This is where the WBO2 putput is located I believe.
Here's the question:
Where is it at? I am not using the beta version.

The patched bin will display the WB AFR in the "IAC Min" box.
100 = 10.0 :1 AFR
200 = 20.0 :1 AFR
The AFR value displayed in DM is the "commanded" value not the actual.
That version doesn't work well for the commanded version. Just get numbers like 445 etc. The newer version has that corrected.
Log with the older one and use the newer version for "display" if you have connection issues with it.
I think you can load the two version and they will co-exist.
Did you add the DXF items so you can select the sensor?

OK, so I was looking at the text file from the DIY WB.... oops. OK, IAC Min is easy to find. Now I feel stupid.... oh well.
I already have the sensor selected, so uhm, the bin file I have is already patched (the AXCN.bin was in the zip file already patched). That is what you are referring to, correct?

You will need to add the two "option" words to your XDF so that the sensor output and connection point are correct.
These will be addresses 2000 and 2001 in your XDF.
You would want bit 5 in the 2000 word and set bit 7 in the second word only if your connecting to "A3", using pin "F14" the bit is cleared.
For troubleshooting you can select bit 0 in the second word to display the "raw counts" that are being input to the ECM instead of a calculated value being output.
You have a 727 so the pins are different.
730 "A3" = C18 on the 727
730 "F14" = C21 on the 727
that is what my info shows, Please double check.
Code:
; KWBOpt: .byte 0x00 ;set default sensor option here ; KWBOpt2: .byte 0x00 ;set default sensor option here ;;***************************** Calibration Section ************************* ; Option Flag for WB O2 Sensor, Option Flag 2 for WB O2 Sensor 7730/7749 Ecm's ; Bit 0 = DIY_TE NonLinear Bit 0 = RAW A/D Output ; Bit 1 = FJO Bit 1 = ; Bit 2 = AEM NonLinear Bit 2 = ; Bit 3 = TE 2.0 Linear Bit 3 = ; Bit 4 = PLXWBLin Bit 4 = ; Bit 5 = Innovate Linear Bit 5 = ; Bit 6 = AEM Linear Bit 6 = ; Bit 7 = Zeitronix Bit 7 = Set pin A3 TPS2 U6 chip read ; Pin F14 = MAP2 U5 Ch 0 ; Pin A3 = TPS2 U6 Ch 0

First off... Thanks a bunch JP for the help
Yeah, C18 and C21.
You will need to add the two "option" words to your XDF so that the sensor output and connection point are correct.
See screen shot... Am I missing something here, or am I just flaking out, I believe the XDF has those words. I have bit 5 of opt flag 1 set and no bit set for opt flag two b/c I tapped the MPA(2)

Should be good to go with those settngs.
Program the LC-1 for 1-2 volt range or you'll go insane.

Why's that Scott? JP?
Mine's working fine with the LC1 (or at least it was until the whole thing went dead last night, gotta check for a fuse before calling them) setting it as a Linear PLX and the LC1 output set to the correct 10-20AFR voltages. Seems to work fine, and I thought the wider range would actually provide a little better resolution.
Am I off base somehow?

You're fine the way you did it too!
I like the wider range myself.

1-2 is how the LC-1 is setup in the code and how the LC-1 is supposed to be setup out of the box.

I'm using the 1/3 setting so I don't get quite as rapid of fluctuations on my display guage - it's more "readable" at the slower setting IMO.

Hey KevosIroc,
How do you like Datamaster? I may be switching to it as my Ease datalogger does not want to work properly and I have a feeling it will nto be cheap to fix it either..

It works OK. I cannot wiat for the next release of TunerPro. Mark told me that it would fix the communication issues with the 90-91 Corvettes.

That's where allot of the confusion has come in with the patch.
The patch function (bit 5) for the LC-1 is setup to use the 1-2 v range but I'm struggling to determine if the AFR should be 10:1 to 20:1 in the setup or left as the 7.35 to 22.39:1. (Math in the patch has me baffled
)Since I havn't had time to figure that out yet I've just been using the default setting and running "raw data" with my ADS doing the scaling.
What settings are other LC-1 users running?

When using the LC-1 bit select in the patch, the LC-1 needs to be setup as
1-2v and 10-20 afr.
If 0-5v use is desired for the LC-1 , then use the plx linear bit and set the LC-1 up for 0-5v & 10-20 afr.
As always, verify your WB output with a volt meter. All sorts of non patch related stuff pops up when adding new wiring/devices.
