ECM programming

What is your question?

The 2011 Accords are advertising 34 MPG hiway. My 2010 with the same engine/power train is said to get 31 MPG hiway. Was this jump in hiway mileage improvement gained with only ECM programming?? Can I get the improved programming installed in my 2010 with out any adverse problems?

only your factory Honda dealer can answer that question. if anyone else attempts this, it will likely void your warranty.
