Hello,  
how can I extend the table for trailing ignition under ignition - Trailing Spark - Delay.  
By default it has only two data points per Axis which will not be enough for a 13b-REW Rotary engine. Adding datapoints did not work for me. Or am I pointing to the wrong table for the trailing spark? On the screenshot you can see that the Xpoints as well Y is greyed out

best regards,
