Hello, Does anyone know where in the AIW file (or elsewhere) that the sector locations are set? No matter what I do with BTB or editing the AIW to set them manually or by percentage, they always seem to be a 33.3% distance on the track. In BTB, it looks like you can set the "window size" for the sector too...and I am thinking wherever that is set is what is causing my problem. Here's what is in the AIW file currently: lap_length=4951.652 sector_1_length=2730 sector_2_length=4450 Something is overriding this. Guitarman's AIWCAM editor is also showing the sectors where I want them. Are they attached to a waypoint? Thanks for all the help!
