I'm starting to get the feeling all your posts are full of shit. First what are you asking? Will a hondata (notice the correct spelling) chipped ECU with honda fuel maps work with a Subaru? (Is that your question?) The answer is an obvious no. Secondly why would you want to add that to a stock WRX? The fact that your don't even seem to know what it is, makes me wonder if you really have it. AND if your other post in the basement about your girlfriend wanting to have a threesome with her friend is true WHY THE HELL ARE YOU EVEN THINKING ABOUT CARS
