OE ProTune Update 3.0.7 HotFix

Fixed some turbo issues + Temperature change in Logs
New: Challenges tab. You get handed a car with a broken tune , You have to find the fault yourself. Baseline dyno pull, dig through the live data with no hints, then name the fault before it lets you fix anything. Six of them, including an open one where the whole job is making as much power as you can without killing it, and a coached version that teaches you the order to do it in. Medals and a result card at the end.

New: bigger tables. 12x12 and 16x16 on top of the standard 6x7. Proper standalone resolution if you want it. The default has not changed so your existing tunes are untouched.

New: valve float. Revving past where the springs give up now costs you power first and the engine second. Cranking the limiter up is not free any more.

New: hard cut limiter controls. Pick ignition or fuel cut, set how far the revs drop before it lets go, and set how long the spark stays off. You can make it machine gun like a drag car or sag like a lazy factory limiter.

Fixed: the 2-step dropping out while you are staged, the app forgetting your page and disconnecting from the car when you open the parts menu.

Diesel people read this one. Three bugs were handing out power that was never real. The Smoke limit slider was moving combustion instead of just the ECU, rail pressure was making power out of nothing, and part throttle was being held back. If your Smoke limit is on the stock 17 nothing changes. If you moved it, your numbers will move. Rolling coal is made a different way now.

Plus a stack of smaller fixes here and thgere, new log channels and UI work.
