AFR reading, SD vs laptop logging

[JAM]

What could cause the AFR to be logged and viewed correctly in MLV when logging through TS directly to the laptop, but then when you look at it when logged to the SD card it shows a reading that is flat lined at .3 AFR?

I don't recall changing anything in the past, I must be missing something somewhere - i did have the laptop hooked up during the logs and the MS3 is seeing the correct AFR, its just not logging and/or displaying correctly in MLV via the SD card

Thanks

What firmware are you on?

Can you post an MSQ?

Reset the SDcard datalog fields. This is an issue with the way TunerStudio handles the fields over a firmware upgrade.

I am on current stable release MS3-

Thanks for the tip, i moved all the fields in the SD logging out and then back in (assuming thats what you meant) and at first glance it seems to be working again .

So should i just plan to do that when I upgrade firmware?

Thanks

In general no, it isn't usually needed, only a logged channel changes address or size. Most often new channels are appended and don't change the existing channels.
