What's New in LegendIQ 3.18 Saving is on by default. New installs keep setup sheets on the device from the first launch, and New Setup will offer to turn saving on if it is off. Gearing now comes from what racers actually run. Tracks with field data show the real ratios and who runs them: Stockton, Roseville, Ukiah, Madera, Lakeport, Shasta, Las Vegas Bullring, Redwood Acres, Alaska, Evergreen, Lorain, Midvale, Barberton, Painesville. Other asphalt ovals show what most of the field runs in that size class, what the rest run, and the exit-speed step. Air cooled cars start on the same gearset as FZ/MT, one step shorter for larger drivers. Final drive. With an FZ09 or MT09 selected, the Powertrain card shows your final drive and every legal rear gear and gearbox combination within 3% of it. Driver style gearing corrected: taller for the momentum driver, shorter for exit speed. Tracks added: Parque Viva (Costa Rica), Barberton Speedway and Painesville Speedway (Ohio). Costa Rica Racing League added to resources. Thanks to JK Kinney, Steve Miko, Ben Matheson, Matthew Benzenbower, and Scott Nichols for the input that shaped this update.
