Hi Hondata Team,

Would like to consult why my AFRCMD is not targeting what I have in the WOT lambda table.

Running on 2.8.6

Attached is the log file and cal.

Thanks!

You need to adjust lean best torque table too

Thanks Jun!

I'll try that out. :)

Please remember that the WOT lambda table is an adjustment, not a target.

So with it being an adjustment table does this mean that the value the table is hilighted on needs to be adjusted to compensate for the difference between the AFR and AFRCMD i.e

AFR= 10.5
AFRCMD= 10.87

WOT lambda adjust value + 0.37 to current value

Is this correct?

It depends what the fuel trims are at that point. The AFM table should be altered, not the WOT lambda.

Ok so just so i understand correctly,

On WOT pull, AFR is not the same as my AFCMD ( the CMD is calculated from the wot adjustment table in a 4 cell interpolation) so to correct AFR to match CMD i alter the AFM table ( say 3.8v-4.5v)

I then reflash and logg a run.

AFR and AFCMD on the WOT pull match very close so AFM table is now calibrated.

So what reason would i ever need to adjust the WOT lambda table or lean best torque table?

Like you say they are not target tables.
