MS3 ECU reflash rumor - is it true?

[MS6S2K]

i know a little more about Cobb than many outside of them do at this point but i'll let them make the announcements when the time comes.



the launches if you look at the 13.8 and 13.1 were equally good. the timeslips show near identical 60ft and reaction times which are indicators of near identical launches. if we use weather as an argument, the 13.1 run was done a few hours after a torrential downpour, thus it could be said (though i am not) that the car should have been even quicker.



based on the extensive dyno testing of the mazdaspeed3 xede with various mods installed and uninstalled as well as the math behind exponentially increasing your ability to reduce a quarter mile time, yes i absolutely do. i plan on getting baselines of this particular vehicle to help support that belief, and if they fall into step with baselines of every other Dynojet run mazdaspeed6, it will.

Well, I'm all for that. A future plug and play 40-50whp reliably, while keeping the car it's smooth quiet luxurious self? I truly hope this ends up being true. My goal is to have a finely tuned car that was meant to come out of the factory like it has 280whp. What I truly want is the same ability I had with my STI, but I realize it likely will never happen. Plug it in, change fuel maps on the fly, and the driving characteristics of the car. The Cobb AP on the STi was truly a magnificant thing, and the car ran so perfectly with it too. I even had an economy fuel map that added a couple mpg for those highway trips, Valet mode that limited the rpms to 3k, anti theft modes, various octane maps to change the way the car accelerated and various power options, boost guage, and the instant ability to revert the car right back to stock instantly.

Hopefully Cobb can hack this ECU and control it, while offering similiar power. If not, I'll be looking into the plug and play Xede system after it's been tested and proven to add this kind of power with no other mods reliably safely, and while making this car run better. The Speed 6 stock is not exactly what I'd call a finely tuned car. Once these ECU tuners coming out are being used by more and used by more people, the top dogs will shine. Hopefully the Xede will be one of them. Thanks.

So I have an appointment for tuesday to have my CAI installed, Is there an ECU reflash or not? should I ask about it?

How does the anti-theft mode work?

How does the anti-theft mode work?

I believe it disables the entire ECU. The only way to get the car to run is to have your Cobb AP handy to plug it in and remove antitheft mode. I guess if you left it in glovebox, you pretty much are screwed, since a thief can plug it in and re-enable it. Since they are serial code protected, only my Cobb AP will work for my car. Another Cobb AP cannot work on my car, and in order for it to work on another you must unmarry the unit. Cobb basically took complete control of the ECU. The mere fact that it adjusts and can remove the rev limiter, you are talking full control of your ECU here. There were two modes on anti-theft for the STI. One started the car, but the moment you revved it it shut off, the other entirely disabled the ECU. Car would not start at all. You need your Cobb AP to get your car running again. I'm just not sure The Mazda ECU will ever be this controllable, but one can still dream.
