Need a calc_pids.txt file for a (PLX serial wideband) to OLSD Auto-VE Please !!!

[RandyWS6]

Im doing OLSD tuning on my 2000 WS6 with a LS3 442cid.stroker,I have done some tuning with my V1 with PLX analog WB, witch worked fine for years . But I upgraded to the V2 and modified the PLX for serial ,but I need a calc_pids.txt for my Serial-WB PLX .I can read the Serial WB on my laptop. But need a MAP so I can AUTO-VE tune. Ive tried building a calc_pids. but with no luck. And been on here for two day reading on Serial WB set up and found a lot of info, but not on the PLX Serial WB, accept on how to mod the serial to the PLX-WB, witch I have done . But had no luck on how to build a calc_pids. to MAP it . Will I need to build something like the analog (BO101) Main-VE BEN.map. I do have the PLX (analog) to the V2 and can Auto-VE with it in need be. I'm not to smart with the new V2 setup yet. But I could build a custom cacl_pids. if I knew what to do. Can any body with a Serial PLX-WB help me please.

Use the calc_pids file from the Calc.VET thread, first post. Calc.VET: correcting MAF and calculating VE (in single log)
Since you're using a serial input, it doesn't matter what type of wideband you have if the v2 is reading what it's saying.
From that calc pids, you can just use CALC.WO2BEN (which is = {GM.EQIVRATIO}*{EXT.WO2LAM1})

Yes I all ready done that and works fine . but the problem that im having is that the CALC.BEN_LAM1 was not matching with the commanded 14.70AFR in my (B3647) The PLX controller is 14.70 AFR and my (B3601) 14.63 AFR and the {GM.EQIVRATIO}*{EXT.WO2LAM1}) is showing 14.81 AFR




The PLX User Guide is in the Attached File.

I found this on here, (B3601) Expression, and it matches what im seeing in my log files . It said it for Analog and im Serial , but it matches perfect. Do I put the 14.81AFR in to my (B3601) to replace the 14.63 ????

This was in EXCEL but had to convert it into text

PLX WB
Maximum Voltage 5.00
Minimum Voltage 0.00 {B3601} Expression
Voltage Range 5.00 {EXT.AD} * 1.9896 + 9.948

PLX WB AFR Expression
Maximum AFR 20.00 {EXT.AD} * 2.0000 + 10.000
PLX WB
Minimum AFR 10.00 Lambda Expression
AFR Range 10.00 {EXT.AD} * 0.1360 + 0.680


Maximum Lambda 1.360
Minimum Lambda 0.680
Lambda Range 0.680


{B3601} To Volts 14.63 2.353
AFR To Volts 14.70 2.350
Lambda To Volts 1.00 2.353

Volts To AFR 2.443 14.89
Volts To Lambda 2.444 1.01
Volts To {B3601} 2.444 14.81





The thing is to how do I build a (Serial MAP) that I can AUTO_VE, or (Copy with Labels) & (Past and Multiply with labels) into my (B0101) Main VE table.

...

{EXT.WO2LAM1} is the what the PLX reports (in text form) regardless of the analog PLX-conversion/V2-deconversion being done...

are you saying that EXT.WO2LAM1 reports 14.81...?

What is the stoich AFR of the fuel you're running...?


( I would ignore AFR and concentrate on BEN calculated from EQR and/or Lambda )

( i.e. forget about CALC.BEN_LAM1, and use CALC.WO2BEN instead )

[RandyWS6]

OK ill try CALC.WO2BEN, How do I build a (Serial MAP BO101 Main VE) that I need to (Copy with Labels) & (Past and Multiply with Labels) to correct the VE tables

(are you saying that EXT.WO2LAM1 reports 14.81...?
No , Im sorry here is what I seen in my log. with 93oct. Fuel

WO2AFR1 14.74
WO2BEN = .996 (GM.EQIVRATIO / EXT.WO2EQR1)
WO2BEN1= .995 (GM.EQIVRATIO * EXT.WO2LAM1)
WO2EQR1= 1.000
WO2LAM1= 1.000

WO2AFR1 14.81
WO2BEN = 1.000 (GM.EQIVRATIO / EXT.WO2EQR1)
WO2BEN1= 1.000 (GM.EQIVRATIO * EXT.WO2LAM1)
WO2EQR1= .996
WO2LAM1= 1.005

The Calc.VET thread shows you how to create a map that matches your VE table...

see post #1 Section I item 4 here: Calc-VET-correcting-MAF-and-calculating-VE-%28in-single-log%29

(are you saying that EXT.WO2LAM1 reports 14.81...?
No , Im sorry here is what I seen in my log. with 93oct. Fuel

WO2AFR1 14.74
WO2BEN = .996 (GM.EQIVRATIO / EXT.WO2EQR1)
WO2BEN1= .995 (GM.EQIVRATIO * EXT.WO2LAM1)
WO2EQR1= 1.000
WO2LAM1= 1.000

WO2AFR1 14.81
WO2BEN = 1.000 (GM.EQIVRATIO / EXT.WO2EQR1)
WO2BEN1= 1.000 (GM.EQIVRATIO * EXT.WO2LAM1)
WO2EQR1= .996
WO2LAM1= 1.005

For each of those what was the value of GM.EQIVRATIO...?

( in both cases GM.EQIVRATIO would have been 0.996... can you see this in your tune file...? )

Post your tune file, your log file, and your calc_pids.txt file.
