Hi Leon,
In GPLTrack Editor, as you are aware, there is the 'poilp' string in the MIRP "PRIM" section when you open ferrari.3do. When you expand this the needle positioner pops up, the Flavor 13 Children 1 node. When you click on it you can change it's position through the X, Y and Z values, but you can also change the rotation axis. The A:? value makes the needle spin around the Z (height) axis. The values are in radians, so π = 3.14 = 180°.

It's a little hard to wrap your head around, at least it was for me, so picture the Z axis as a tree, and you standing next to it as the needle. A third person is looking at you and the tree, with you on the left of the tree. If you walk half a circle around the tree (180°) you'll be on the other side of the tree, facing the other way than before. For the third person, you are now on the right of the tree, and left and right are switched around compared to before. In the case of the gauge needle, it means it now starts far right (3 o'clock position) instead of far left (9 o'clock position) and moves clockwise to the 6 o'clock position, as opposed to counterclockwise before. Of course in GPL, you will now be seeing the back of the needle instead of the front, but you can't tell the difference
. Hope this explanation made any sense.

The B:? value makes the needle spin around the Y (width) axis. The C:? value should make the needle spin around the X (lenght) axis, but that feature doesn't seem to work somehow. But there are workarounds for this, not so much for the B and A values so thankfully they work
.
Back to the point, if you put in a B:? value of π = 3.14, your needle will flip 180° around the Y axis and it will now move clockwise from 9 to 12 o'clock
. You'll be seeing the back of the needle as you've rotated it 180° from the driver viewpoint but as said before, there's no difference
.
So put in a B:? value of π = 3.14 for your poilp MIRP string
.
Tommie.
