Thinking of reseting ECU
My friend drove my car yesterday
and he said my car's first response (I dont know what he really means...)
is much slower than he expected.
He said my car seems to have droven like a sedan instead of a sports car.
He said I can reset my ECU and that will result in faster first response
If it does make my car any faster, I would do it.
Any thoughts??
Also what are some things that I should be aware after I reset the ECU?
Thanks

My friend said I could reset it at the Mazda dealer and it will be very quick.
Should i do it?

OK, we'll take this seriously.
Our cars, as most modern vehicles, have an ECU that is controlled by software (firmware) that may be modified.
Mazda has put out several "flashes" to the ECU over the past few years, mainly dealing with oil metering to better augment/protect the rotor seals and also an emissions voluntary recall. There have been no real performance flashes per se.
The Cobb Accessport tuner however provides the medium for performance enhancements, but at a significant cost. http://www.cobbtuning.com/products/?id=3812
Racing Beat also provides a one-time flash at lower cost, but you must ship your ECU to them.
Now you know more than your friend.

Also adding to the serious response... If you friend has a car with a lot of low end torque (like a Mustang GT) he would not have been expecting the RX-8's low torque, high rpm characteristics. It's not a stump puller. Also, he may be aware of cars whose ECUs can easily be remapped to get more power. The 8 is not like that, other than the two vendors Huey cited.
With 2 1/2 months under your belt, you should have the hang of manual. Let the engine rev - it's made to do that. Try shifting at 5000 rpm in normal driving, and make sure you go up to red line when you can. (Usually in 2nd when getting onto a freeway, if you want to stay legal.) It might cost you a little in gas mileage, but you'll be getting your money's worth.

I think I know what your friend is talking about. Some cars have a learning ECU which learns the typical behavior patterns of the driver, and will then respond to throttle inputs accordingly. What your friend is suggesting is that because the car has been driven gently, it will learn that behavior, and then respond gently to your inputs, if you generally drove more aggressively it would in turn respond more aggressively.
I don't know if the 8 has this feature or not, and to be honest it doesn't really matter if it does or not. ECUs which have this feature continue learning, they don't just reach a cut off point and stop, so if you have been driving gently and then start driving more aggressively it will start to learn your new driving style, I believe it can take a couple of weeks to fully train it. If you reset the ECU it would be quicker, but since you say you are still getting used to driving MT then why not just let it learn with you.
I believe this feature exists to help balance fuel consumption and performance, so I would suspect the 8 doesn't have it.

Hmm,
I thought i was the only one!
This could be terms for a new ecu flash -- i want my rx8 running good ALL the time.
Its not the weather either cause -- if im running the car for like an 20 mins and then shut it off and go eat and come back its not running like before. Its like random at which it runs at optimum performance.
I'm hoping my accessport can solve the problem.
