help with eratic tune changes
My tune did something crazy today, it decided to go extremly lean on the low end with no changes to the tables. I realize that it has been colder outside , but i have driven it for about two weeks as a daily driver now and it was fine. the A/F went from (12.5-13.5) on the low end up to (16.5-17.5). any ideas on what might change this?
here is a quick rundown of my setup:
383 stroker
procharger on 12lbs
OLSD

Well the car is back to normal now, I just retunned the low end. But it still bothers me that it just went lean with no changes. Before today I had not flashed the computer for over 2 months. All I can come up with is that the cold weather did it. If anyone has any ideas let me know.

Since you are running OLSD, it was likely the weather that did it... One of the nice things I like about using EFILives custom operating systems with semi-open loop speed density tuning - no problems with weather changes...
