I guess that as that may be an option with the software but that is not the way your tune is setup.
Thanks!

Pat,
Correct, but notice the Air Temperature is used to calculate speed density. Well where does the Air Temperature come from? It comes from inside the MAF sensor so you still need the MAF sensor unless you decide to run an external temp sensor which can also be done. Something we are looking into with our FlexFuel system.
