Small bug reagarding the display of the AFR value

While driving and sometimes at the first connection to the LC1, the AFR displayed is not 20.9 but 209 (or 148.7 instead of 14.87).
It does it for a very short time, randomly.
That makes the average and max values wrong in the AFR tracer.

must be a race condition when between setting the multipliers and when the data is received. i'll note it down to check

does it continuously occur at any time? if you can send a log though that will help me out...

you can reset the AFR trace to get the values again

Do you see it in log record playback or only wideband?

I can see the values multiplied by 10 everywhere, it comes, it goes.
Have a look to the files.
The log record starts with 209 instead of 20.9 !
Your Nistune logs shows the same.

Hi Matt,
I noticed today after a long day out at WSID that our trusty VLplusT (11.2@121) and Nistune were causing some issues with AFR readings.

attached is a pic of the problem.

I have started to fine tune this car and I'm just not sure which readouts I should go off. the afr readout in log player, the afr readout on the timing map or readout in the fuel map. they can be different. I may resort to logworks to compare. now that adds a new dimension. usually around .30 or so.

check if still doing this with the latest version. i fixed some issues regarding the AFR display (finally found the issue)

Matt,
I've been using nov25th version 9.13.12b.

Looking at the changes via log player, it would seem that there is a slight delay between the log player AFR value and the one displayed on the timing/fuel maps.
Are the different places were AFRs are displayed throughout NisTune working off the same log player time stamp or is there a specific reason why they shouldn't?

Kind Regards
Sime
