RE: Engine tuning question
when it comes to tuning, a lot of it depends on where you live and the day to day weather conditions.
stuff like humidity, barometric pressure and such.
say you had a cloudy, cool, day with low humidity which would leave the air with more oxygen than normal so you would run slightly richer
on the flip side if you had a sunny, clear, and high humidity which would leave the air with less oxygen than normal so you would run slightly leaner.
it really depends on the weather
if you live in a place where the weather changes like a womans mind then tuning may be a regular thing.
if you live where the weather is a consistant thing and very predictable then you may not have to tune from day to day for months.
i live in cali and here lately it's been a crap shoot due to nutty weather this year.
however, once you learn more about tuning it is really easy especially if you know what to listen for.
