Hi, as I've been using this newly discovered feature, I've noticed I've been getting some incorrect values from 3D tables when the output needs interpolation along the y-axis.

Example 1:

Example1 is provided as a reference showing the correct output when the y-axis does not require interpolation since RPM = 5216 falls directly on the y-axis.



Example 2:

For Example2, all variables are the same as Example1 except RPM = 6207.
For the AlphaN - IACV (TPS Compensation) map, the output has been interpolated along the x-axis instead of the y-axis.
For the AlphaN - IACV map, the output has also been interpolated along the x-axis instead of the y-axis.
For the AlphaN - TPS map, the output has also been interpolated along the x-axis instead of the y-axis.

I have tested with many different values along the y-axis and always get the same type of error. The only time the output is correct is when the chosen y-value falls directly on the y-axis.

I've attached the ECU definition file.

I am using Romraider Version: 1.0.0 DEC01 2023, Build: 1214
Windows 10 Home

Thank you!
