is there a pro or a con to tuning in the winter vs the summer. I'm sure the a/f will change a bit but not enough to matter. Trying to decide whether to dyno tune now in the cold weather or wait till it warms up. Also which is more important the leaning because of colder air or the possible detonation with the 90+ degree days of summer

BTR may be able to chime in here, as they're the only vendor we have (that I know of?) offering tunes for the Genesis at the moment.



They're holding a dyno tune event in Ohio in April, if you're interested. Check out their vendor forum for more details.

Technically it shouldn't make a difference when you tune, as the computer has built in correction factors for intake air temp and coolant temp etc. However, there might be parts of your map that aren't tuned as accurately as they can be because the tuner is simply guessing how the car will perform at the other extreme of temperature.





Just do it now, if there are any huge issues you can always get a 'touch up' tune done at a later point.
