AFR not being logged after upgrade to MS3

[jb007]

Hi. Not sure if I have this in the right section, feel free to move if required. I have recently upgraded from an MS2 to MS3, as well as changing my O2 sensor to a 14point7 spartan unit.

All AFR meters work within TunerStudio, including a WUE session I have just carried out, BUT AFR does not show within MegaLogviewer. Looking within the datalog the AFR just reads a low value... 0.3.

What have I done wrong, or is this a firmware problem as it outputs the AFR whilst running, but not whilst logging?

EDIT: I've only used the logging to SD card, not the TunerStudio Data Logging/Start Logging menu i.e. I've just imported/converted the MS3 files from the SD card.

There appears to be some invalid values in your MS3 file's header. I'mm looking into this further as it seems TunerStudio should be reporting a problem when transforming it.

Actually the MS3 header looks Ok. Still researching.

Thanks for looking in to this. I've just come back from a 230Km drive (using your brilliant Autotune) and the AFR is being logged using the menu logging method (Ctrl L).

One sort of important thing here.
The fields logged in the MS3 file don't match the ones currently selected in your msq. Is the AFR still logging with a near 0 value?

Thanks for looking in to this. I did ~230km using the logging within TunerStudio; all was ok with the AFR's etc. Just retrieved the SDCard which also was logging the whole time and the AFR's are now coming out. Go figure! I believe I have not changed anything, so I'm not sure whats going on. I've attached the last MS3 and converted MSL and MSQ file for your perusal.

This MS3 was originally a MS2, and has had a variety of firmwares loaded. As a MS3 it has run on the bench with Jimstim with the latest production firmware 3.2? and Alpha 8 and now 9.
