Thank you so much. Now I have this stupid issue when air intake temp changes!
When air intake temp increases, the fuel trim will increase in positive at Park in Gear.. say 4-5% - not Park in Neutral. However the cruising fuel trim still spots on!!!
Then intake air temp decreases, the fuel trim at Park in Gear (when you stop at traffic light and such) the fuel trim will move towards zero again. No affect on cruise fuel trim though.
As air intake temp increases, the idle will be more rough and load increases as well in Park in Gear - REV will vary between 550-580RPM
As air intake temp decrease, the idle will be a lot smoother and load will decrease while REV will be close to 550RPM as set up
I am really annoyed about the condition of the tune changing with Air intake TEMP, must be some Air temp compensation vs Fuel!!!
