Need some help.

[J.Abbott]

Does this look right. I can't get the pid for the Lambda error to work. It just comes up with a Red X. Any help would awesome. I have a allot of new gray hairs trying to figure this out.
Thanks

What does it say when you right click on the pid & select more info. I would say that you havent selected one or more of the parameters that your pid needs.

Try validating all PIDs.
This happened to me recently with a different PID and I didn't think this would be needed because it's a calc_pid.

Also his won't give you "Lambda error".
It will give you a multiplier based on AFR and most likely it won't match the stoich AFR set in the PCM.

The default wideband PIDs are helpful but the AFX one in particular isn't right for most people.

The AFX PID ({EXT.AD1}*1.4)+9 is for a 14.57:1 stoich AFR.
I don't suggest simply changing the PCM's stoich AFR for this either.
Create a new PID formula based on the Stoichiometric Air Fuel Ratio in the PCM.

In CLC-00-027 replace {CALC.NGK_AFR} with {CALC.NGK_AFR.AFR}.

[ CALC.NGK_AFR has two instances (one for V and one for AFR), you have to specify which one ]

Post your calc_pids.txt here.

It did not change, it now says the error is in Position 19 instead of 15. any ideas?

"The AFX PID ({EXT.AD1}*1.4)+9 is for a 14.57:1 stoich AFR"
Can you elaborate on this, I thought a WB was just a voltage output and depending on what the voltage is, is what your A/F. It should not know what stoich is, that depends on what I make it. I like some more info on that, because it does not make sense to me, I may be wrong, and you are right, but I would like to know where they information came from and why it is.
Thanks

"Invalid PID, unknown parameter in position 15"

Can you post your calc_pids.txt file.

Connect laptop to vehicle and do Validate Pids.

I try to explain this here:
How to match wideband output to {B3601}

In the spreadsheet replace the minimum and maximum Lambda values in cells B10 & B11 with the AFX's values (0.62 & 1.10)
and in cell B13 place the PCM's AFR value for stoich (Lambda1.00/EQ 1.00).

The spreadsheet will create a formula for a new calc_pid for the multiplier based on AFR.
Not a perfect solution but if commanded EQ (or Lambda) are not available from the PCM this is the way to go.

This is one of the reasons a lot of people used Lambda or Equivalence Ratio.
The LS1 has a commanded EQ PID that I use with serial EQ output for the multiplier.
I don't know if that is available for your PCM.
