Calc.VET, Desired Airflow, Idle RPM, A/C and questions related to these within...

[sac811]

1. Should I do Calc.VET or Desired Airflow first in tuning?

2. Should I do Calc.VET with A/C on or off (other than WOT of course)?

3. Should I do Desired Airflow with A/C on or off? Or do you just let the A/C tables in the Idle section take care of it, and just do desired airflow without A/C?

4. Lastly assuming I have gotten my idle down perfect at say 725 rpms (in my 6.0 cam, heads, full bolt on engine), what would be the most important things in the tune to work on to be able to drop the rpms at idle to 600-650?/Or does dropping the rpms at idle even result in any benefits such as mpg, etc.?

5. With Calc.VET, I have read that you can choose to just use the WB02 input and not the LTFTs. But if I have MAF at 400 (Open Loop), and LTFTs Disabled, Do I still need to log LTFT1 and LTFT2 to show 0 for the LTFTBEN calculation?/Or can I not log the LTFTs and leave off the LTFTBEN Calculation and it still work correctly?

Thank you
