Rob for the honda world there would be alot better choices then that AEM unit. Hondata, EcTune, Crome Pro, Neptune and a few others depending on OBD will let you adjust low and high fuel and ignition tables aswell as 2nd maps for if you have race gas tune and pump gas tune you can switch between. also plenty of Aux controls and great means of protection when your engine is cold or even if your car leans out.
But that unit would be great for cars that dont have the stock PCM ability's to change.
