Can a stand alone ecu, like the zdyne or aem, give you less hp but more gass mileage, like can you put it on effiecint mode or something and allow you to get like 40+ mpg?? I'm just curious I know this wouldn't be the only benefit, but i'm wondering what all they can do, thanks.

 

yes there are some maps that you could set up like that, or just tune right across the board, youll save gas and youll get goodhp. they adsjust spark maps fuel maps and timming. If you have a laptop then you can tune while on the fly (im positive about this if you have Zdyne not sure with others such as hondata you have to burn a chip everytune,)

Good Luck
