Unlike more rabid racers, I only tune once a season. I was wondering if there is a guide for adjusting for temperature changes? For example, Saturday I will spend the day at Lebanon Valley Dragway finishing up my tune. The temperature will average low 80's if the weather gods are accurate and benevolent. So let's say in the fall I am racing and the temperature is low 60's. Absent re-tuning is there a general rule on adjusting fuel to accommodate change in temperature from when the car was dialed in? I know that in general we go leaner in warmer weather to accommodate the less dense air and the opposite in colder air but wondering if there is a handy guide as to how much per 10 degrees for example. Thanks
