So, on my 2009.......what exactly would i look for to see that the fuel map has been reset after doing the brake thing.....there isn't quite a oil pressure gauge to look at

 

I don't understand the question.

 

He asks for the procedure to reset the ECU in a RX-8 2009

 

going to take a guess. pull the room fuse, or pull the battery cable and step on the brake for a second or two..

Damn... I didn't realize that.
How would you know in the '09?
I'm interested to know this too.

I guess one way to know is wait for a CEL and then try it.
When I ran catless (and before my AccessPort) I would do the 20x brake dance to clear the CEL.

 

y-e-a.....i wanna do it, 2700 miles on my car now, but i would love to know what exactly happens when this is successful to alert you to the fact lol

 

do it and see if something sweeps

 

I haven't done it yet...anyone w/ some additional advice?

 

Don't all 09's have DSC and if you have to do the DSC reset then you know you've done it? Or do you have to do the reset anytime the battery is disconnected?

 

DSC reset happens anytime the battery is disconnected.

 

The reset procedure is explained in great detail here (including the '09 models):
