whats the point of swaping out an ecu.....say like if i put a mugen typeR ecu in my gsr? would that even work? what would it do? 
On a stock gsr? It would do nothing; even make you lose power.
The topic's been covered before, but you're better off saving up for hondata or even a relatively cheap V-AFC and some dyno time. ECU's are specific towards a particular application, so there's no one size fits all.
