CALC.TTE working in Data Grid, not on dashboard

[Binaryman]

As the subject says, I can look at the PID for CALC.TTE in the data grid and get an accurate number. If I put it on a dashboard however, I just get 0.00 (I'm using %.2f for format string). Yes, I'm obviously checked use OBDII value, and using value(number). It doesn't make sense to me... everything else on this dashboard I've tried to do works fine.

Any suggestions?
