New - Reminders: get a nudge when customers are waiting at your shop or a lesson is left to do. At most one a day, never at night. Turn them on or off in Setup. - Sharper engine parts on iPhone and iPad. - After a dyno pull, the dyno goes back to the mode, rpm and throttle you had set, instead of holding at 2500 rpm. - A short note after each update shows what changed.

Fixes - On shorter iPhones (iPhone 16 Pro, mini, SE, and any iPhone with Display Zoom on) the throttle buttons, the dyno controls and the table edit buttons could sit off the bottom of the screen. Everything fits now, and table numbers shrink to fit their cells instead of running together. - 80 and 92 mm throttle bodies no longer make a naturally aspirated engine surge and lose power. - Spark plug gaps now take effect. Every engine used to run a 0.024 in gap whatever you fitted. - Very large injectors (2200 cc) now start the engine on the base tune. New - Detailed engine bays: turbos, superchargers, intakes, throttle bodies, filters, fuel rails and injectors, nitrous kits, belt drives, front covers, blow-off valves and wastegates, with hoses and pipes routed around the engine. - New part: Factory TVS 1.9 L supercharger. - Engine sound: each cylinder's pulse travels its own header length, so flat fours and unequal headers sound the part. - Big cams lope at idle. Raise the idle target to smooth it out. - Roots and twin-screw blowers sound different. - A big fuel pump on a small feed line now loses pressure at high flow.
