Just as an Information. @Nicola59 reported (thank you for that ) a Problem, that the Entries for the Turbo in the exported Engine.ini didn't appear, even if he set an Inertia Value in Cell C40 in the Engine2 Tab. I've checked it and it was caused by a Typo in CellAC64, where you will find the Value ..596 (Screenshot below), which is no valid Number and the Spreadsheet throws an Error, which prevents that the Turbo Entries get included. You can fix that, by replacing the ..596 with 0.7 (which is from the same Table of a former Spreadsheet Version).
Assuming anyone is using a turbo but decides to use those example figures, I'd probably stick with 0.596 rather than 0.700. (in older spreadsheet versions, the 0.7 was the peak for that line; above the 0.742 is the peak) So still fixing it (0.596 instead of ..596), but probably the intended value.
@redapg & @Nicola59 thanks for posting this info... I recall struggling with this error, and it took me some time to figure out why it didnt export turbo correctly, but never thought of posting my findings because I was so relieved that it was finally solved...
@Lazza You probably are right. When i checked it, i was a little bit in hurry and so i mainly was focussed on fixing the Problem and when i did make the Post here, i only checked the Columns and not the Rows. And in the Column, the directly above and below Values are identical and so i didn't check the whole Column and Row. Shame on me. But i guess that there wouldn't have been a noticeable Difference between 0.7 and 0.596 in Game.
