Greddy Emanage
 

So my brother said I can have his Emanage right off of his 240sx. It sounds like a great idea but im not sure. Will an Emanage work on my N/A 04 rx8?? and if so, how or where can i tune it? DO i have to take it to get a dyno?

Don't even take it if it's free.

It's complete garbage. Anything you can do with it is going to be fighting the RX-8's ECU constantly, and the RX-8's ECU is going to win. You are not likely to get any power from it, and you ARE likely to damage the motor trying.

Get an AccessPORT or MazdaEdit if you want to tune. They change the ECU directly.

^ This.

This is so................. 2005 ;)
