Japan8

As I said in another thread... that wasn't my point. My point was that since they did it in Japan, we can do it in the US. NOthing more.

Companies that want to offer an ECU flasher for the RX-8 may want to talk to one of the JDM shops about a business deal if they don't want to invest the time and energy into cracking it for themselves. But I wouldn't hold my breath.

On a side note... all major JDM shops are able to flash the ECU (FEED, Knight Sports, RE Amemiya, RMagic, etc.). It's hardly an industry secret among them...

Hey Japan,
How are you? Do you know what kind of documented wheel hp numbers they may be seeing?

they have magic dynos that generate higher numbers for the parts they sell than we've been able to duplicate here ..

They do, the same thing everyone is discussing about now. The MPS 8 comes with a different mapping on the PCM.

OK, I see where you're coming from now.

I was under the impression that the JDM shops are getting "insider" help from Mazda ....

RE Amemiya
http://www.re-amemiya.co.jp/rx_8/rx_8_cpu_redom.html

Improved "feeling" and around 15ps increase from Muffler, Header, Intake filter change. When combined with ECU tuning they are claiming 10-25ps.

KnightSports
http://www2.ocn.ne.jp/%7Eknight78/SE3P.htm
Muffler only about 6hp. Fuel and timing added another 6-7hp for 11-12hp increase. They have some details about what they've found with the ECU and their results posted as well.

Supercharger makes 292hp and is available for sale. ECU is stock with reflash.

And a light flywheel, high flow cat, cat-back and some kind of intake change (but it wasn't really clear what in old stuff I've read).

Japan8

Ok... cool.

Nah, I didn't mean that the shops had gotten help from Mazda at all. Particularly if you check out the RE Amemiya article in the latest Option magazine, you can see that they cracked it on their own.

BaronVonBigmeat

Wow...you'd think that one of them would arrange to sell it in the USA...or an american company would work out a deal to buy their secrets, and/or act as their overseas sales rep.

Are they selling replacement ECU's or just a reflashing tool? All I can see is a picture of a metal box and a bunch of question marks. I wonder if their method would work on a US 8 at all...or would it simply show Japanese characters when you're tuning it, heh.

Japan8

^^Neither. If you check what I posted about it in the "Fujita Engineering" thread, I said that you have to either send them your ECU or bring your car into their shop for reflash/tuning. They offer to also put your tune back on again in the event that the dealer flashed over it for 3,000 yen. The basic tune (rev limit, speed limit removed) is like 50,000 yen and the full tune (fuel, ignition, SDAIS, cooling fan, throttle (Knight Sports), and more) for 100,000 yen.

The same thought has occurred to me... why hasn't anyone in the US talked to them to see what, if any, kind of arrangements can be worked out?

TeamRX8

so far they have declined to to anything but JDM spec, probably because they don't have access to those vehicles for testing

blown-up customer engines aren't to be taken lightly, which is probably why the advertised results aren't that overly impressive

Brice-RX8

Why is Mazda so secretive about what is within the ECU, seems they would accomplish more with other people out in the industry programming on it, when that is all those people do?

Japan8

Either one of two things or both of them...

Corporate liability concerns

It's a Japanese thing (think Sony)

Personally I think both are utter bullshit... but that's me. There's plenty of synergy between US automakers (particularly Ford) and the aftermarket. Seems to be for some of the German makes too. Go figure.

corporate liability would be the stronger case as far as Mazda goes... the tuner shops want to make money on their products as well...

If someone can produce the open source variety, which I indend to look at, then you will still need the right tools to get readings to go off of and the right tools to flash your car as well.

seikx8, have you deciphered any more of this map?

Japan8

But that is still a weak arguement at best. Like why doesn't Mazda offer any REAL aftermarket parts for their cars besides appearance stuff and suspension? Liability is a load of ****. Ford offers plenty of parts for the 2005/6 Mustang, upgraded S/C for the 2003 Cobra and Lightening and S/C for the SVT Focus through Ford Racing. GM offers upgrades for the Cobalt SS. Chrysler offers upgrades for the SRT-4. Even Toyota offers S/C for the Tacoma X-Runner and Scion Tc. Aftermarket companies... Saleen offers a s/c for the 2005/6 Mustang GT that Ford does not void the factory warranty on. ECU tuning... ECU flash (pre-programmed). Kenne Bell has a kit that they warranty too and its tuning is the same method. I don't see what Mazda's problem is.

I like that too. Even better if the equipment can be purchased in "kit" form and then you just have to DL the necessary software...

you make some good points, but you nor I am Mazda "suits", so we have to do it regular style...

You would not prefer that we just give up would you?

We all know that the interceptor and microtech properly tuned leads to measurable and worthwhile performance improvements.I for one have driven a microtech tuned rx8 on an otherwise stock Rx8 and the performance improvement was indeed significant.
Racing beat has decifered the maps but says that only negligable gains have been obtained and has put further development on the backburner.
This to me appears strange. Racing beat HAS the knowhow to properly tune our maps Im sure and to reflash our ecu. Its time that people power let Racingbeat know that they REALLY want this to go ahead.
It appears dumbfounding to me that the premium rotary performance arm in America basically to this stage only offer a catback exhaust offering very minimal hp gains and a revi intake again offering minimal gains. Its time racingbeat took up this challenge for ALL of us rx8 owners craving further performance, and better economy( as a side benefit),to boot!!!!!

Got all the data cleaned up wiht all the Axis. Still need to extract the map values corresponding to those axis.

Here are two maps that look like L&T ignition for idling.

ok, to the other poster, I am not advocating doing this for profit in any way, if the idea of cracking it gets dollar signs in your head, then this is the wrong reason in my opinion... the purpose here is community based and free for all to participate and reap the benefits...

Allot of people have been spending allot of their personal time on this, and so I would hope that they are recognized.

One thing that I think would help seikx8, is 2 specific files posted.

the first being an unmolested version of the map as you have dechiphered so far

the second is simply the same version, but with highlights denoting what is what, or what you surmise is what...

basically a complete one and another one with your comments.

this way, we can get the tuning guys to look at it more closely.

it will definately help me, but hoping that would help the others guys as well.

MrJynx

this is some great stuff, i've been crazy busy with work and haven't been able to check this thread out to much until today (which I just read everything eventhough I have a meeting to prep for.. lol)

I can basically decipher the data that has already been posted, but is there a website I can check out for additional info about the actual timings and the other info in these maps. I know computers, but I don't know what the timing values actually mean (Maybe something like a Tuning cars for dummies

They are tied to close to MNAO for this to happen to be a street legal mod, especially in Calif.

What they should do, is create a "Skunkworks" arm separate from the main office, and create stealth mods for us.
