Beta Advanced Engine Tuning and Wear 1.4

I'm unable to recreate your issue, surprisingly 0.39 didn't do anything regarding engines so this mod didn't get many changes. I have added some new features recently, but nothing regarding piston wear or temps. It could be an issue with UI wear multiplier, maybe try messing with that or try an older version of the mod as they should still work in 0.39. Also make sure the piston crown temp isn't above ~800F for some reason as the thermal system I added might not work as expected on certain engines.

Thanks, the mod is integrated with the vanilla partCondition system so you can use "extensions.partCondition.initConditions(nil, METERS, INTEGRITY, 1)" to set starting mileage and wear.

Thank you, but I cannot recreate your issue. Several diesel engine packs I tested seem to work fine, and the only time they break this mod is if they add their own combustionEngine lua conflicting with this mod (which most don't). If you can post the error and mods to https://www.beamng.com/threads/advanced-engine-tuning.108871/ I can see if there's anything I can do about it.
