Datalog Records do not match Table Records?

[griffida]

I have recently moved to Alpha-N for Spark (Previously Speed Density) and find that the MegalogView datalog "Spark Advance" records in the log do not match the "Advance Table 1" records displayed in he table. They are 3 - 8 degrees out, see attached log. When I check the other Spark log options, none of them appear to account for this variation? (ie Cold, External, Base, Correction, MAT, Flex Advance, etc)
What am I missing here?

In megalog viewer do you have the right tune file opened?

[griffida]

Yes, I have the right Tune file. I have several Logs/Tunes showing a similar discrepancy.

Check to see that MLV is tracking the Y Axis of the spark table to TPS instead of MAP.

On the main menu:
Options --> Default Y Axis Field

Thanks for suggestion Phil. When I change MLV Options I get the following:
"Tune setting must be reloaded for change to take effect." When I click OK, nothing happens.

When I reload MLV and the tune I get:
"The Y axis field 'TP' (or TPS 8bit) not found in current datalog. Set the correct Y axis field in Options Menu for table highlighting and VE Analysis to work correctly."

I am using Speed Density for fueling and Alpha-N for Spark ?
Where do TP and TPS 8bit come in?
Appreciate your help, thanks.

Use the actual log file name of your TPS signal.

What is the TPS filed name in the log?
