RX8 auto is limited at 200km/hr(123mile/hr)

Hybrid-RX8

This would be nice.......it would be like Subaru guys....with their ECUTEK reflashes...

One item I would like control over is the vector for the parameter 'tiresize' in revs/mile or revs/km so as to be able to correct for (obviously) different than OEM tires and rear axle ratios so speedo reads correctly. Thanks.

the limiter on my my manual type S (6 speed) cuts in at 187 kph on the flat (although it went to 200 down-hill once)

Why are you asking us? You are the one that has cracked the PCM! You tell me to what the limits are set!
While you are at it, tell me something actually useful like what is the granularity of the OEM MAPs? How is the enrichment timing table handled? Does it have a load axis or just RPM?
Have you found the checksum for the aux stuff like TPMS, ABS, EPS, etc?
These are the kinds of things I want to know and you HAVE to know to do what you claim.
If you are asking us for what the governor is set, then you haven't a clue...

I am in Ocala. Feel free to use my 6sp Manual as a test bed. Feel free to call me.

John,

I would edit the post and remove your phone number, you will be surprised how many wierd phone calls you can get. Remember the internet is open to all. I would sent it to them in a PM. Just my .02

John Corbitt

Thank you Tigster.

The info displayed below is from a Mazda6 which is at a similar level of development that we are at with reversing the 8. We are not going to turn this thread into something negative nor should we have to prove to YOU that we are capable. It appears that you may be working for someone else (and can't figure it out) or you are just another nea sayer. If you have a clue of what you're saying, you'll understand the info shown below here.

I'm not gonna jeopardize a possible good thing, so I will no longer respond to any questions like yours. If you feel that we can't handle this project then stop viewing/responding to this thread. I can get the answers to my questions from the guys who are interested. It's obvious that you're not interested in us developing software/hardware for the RX8. That's one vote. Is there anyone else who feels that we're wasting yours and our time? If you don't want to answer the questions I ask then how about just not responding.

Obviously, I am interested - so far I am the only one that has actually supplied you with any real answers to the questions you are asking.
I also understand the ROM dump you posted and I also see that it is not real (i.e. - it has been marked up to make it unidentifiable, not that it wasn't originally from a real car of some sort; it isn't a native dump, however - it is compiled by some sort of interpreter via CAN rather than pin-level).
I am not a competitor - I don't have those sort of resources. However, it would be in your best interests to not **** off me or others like me because we would otherwise be your best (volume) customer.
I am worried that you are another "SuperChips" or similar. You have yet to respond to the specifics of what you are doing.

fastsvtss

Not looking to **** anyone off. Just looking for some help that could speed up the development process. We're going to do this project no matter what. With some help the project could be done pretty quickly. With no help, the project could take many months.

What did you mean when you said "I am worried that you are another Superchips or similar?" What are your concerns? That I'm wasting everyone's time (including mine)?

MazdaManiac

Yes. The vast majority of the PROM business in this industry is controlled by companies that, at best, figured out how to tweak ignition timing a few degrees and claim all kinds of gains.
What you are purporting to do is give the tuner complete control over any and all aspects of engine control that fall under the dominion of the OEM PCM.
This is nothing short of an absolute miracle (and one that would change EVERYTHING in the RX-8 aftermarket) and your rather non-chalant attitude is disturbing.
I can't even imagine an undertaking like that without first having a complete understanding of what is possible.
Asking here (or on the other forum) "What would you like to do?" seems, well, really strange to put it bluntly. It raises a BS flag. Sorry, but that is how it looks.

If you are REALLY serious, I could lay out the entire RX-8 control scheme for you.
I just need some indication that this is for real and so far you haven't done that.

It is in your best interest to get MazdaManiac on your side. He has been a major contributor to the forum and RX8 community. Do a few searches and you can see his wealth of knowledge and his willingness to share it with no $ gain for himself. Maybe you can hire him and speed up this project!! If your company can do what it says it can prove this to MazdaManiac. If you get his support it will greatly increase your sales.

Another Maniac for President endorsement - it's hasn't just been RX8 - it's been Mazdas period. I remember reading him being on the cutting edge of Mazda piston-engine tuning for the past 6 years or so; And who knows how long he's been 'that good', as I only discovered the internet in 1997 or so.

Yeah! Me for Prezidint!
Just what this country needs! An old, angry Dane putting a rotary in every garage!

If you could develop a handheld tuner to reflash the computer for more performance and allow me to run a catless midpipe without a CEL, I would without a doubt buy your unit. I have yet to mod my RX-8 because all parts have been so shitty. If a performance tune and a race midpipe could show somewhere in the 20-30 hp increase, I would buy the unit in a heartbeat.

TrackAddict

Thanks for this! Please keep up the development work. MazdaManiac does not speak for me.

For what it's worth, the 6sp RX8 has no speed limiter.

MazdaManiac

iTrader: (3)

Yeah it does, but it is soft. Somewhere in the 145 MPH range. Guys that pass that on a dyno do so because the front wheels aren't moving. No speed measurement, no limit!

Yes I do! I am your Sensei! BOW TO YOUR SENSEI!

Spin9k

IMHO Posters should READ what they write 1st and perhaps think about how it sounds before posting it.

Case in point - THIS THREAD WAS ONLY STARTED 12-31-2005, 09:41 AM for heavens sake!

So now we're at 3 DAYS and 5 hours and counting and someone who professes to know alot is yelling at someone who just showed up to possibly HELP US and doubting their intentions, their knowledge and their integrity???

Why not develop just a shred of tolerance and hold the nastiness oh...I don't know ... maybe tell they actually DO SOMETHING to DESERVE IT?

Yes that's yelling! Get over yourself and grow up - act with some regard for other feelings and their offers of assistance! We are all supposed to be adults here.

Shhesh! So flame away, I would expect.

MazdaManiac

iTrader: (3)

No one is bashing this guy, least of all me. I am BEGGING him to do this. It would be an incredible asset.
However, no one could possibly undertake this effort and not know simple thigs like "what would you like to control" and "what is the speed limit".
As soon as the ROM is cracked, these things would be obvious.

I profess nothing. All I "know" is laid out here to see. I'd like to see the same from such a grand claim. Adult is not equivalent to sheep.

Red Devil

Perhaps, "what would you like to control" was more an ancillary question. Such as someone earlier spoke of controlling the ECU to adapt for different wheel/tire sizes to get accurate speedometer readings. Who developing would think of something like that? If you're not a part of the RX-8 community such a suggestion may be an afterthought, if that. His asking for what features we would like says to me this is possibly someone that is wishing to cater to our specific needs and not deliver us a cookie-cutter system.

I'll give anyone a fair chance when they come here. Most have disappointed, but some have been favorable. My disappointment has always stemmed from people promising finish dates or promising that they can deliver more than they really offer.

fastsvtss

Hopefully this will be my last response in regards to MazdaManiac (I don't want to be misunderstood or misleading to anyone).
1. I never claimed any specific power gains (we are not that far along in development).
2. Even though we do have software that gives a individual COMPLETE control of their ecm for the Ford market, I didn't state that's what our first release will be for the Mazda's. We will be releasing software/hardware in different stages. Obviously the early releases will be more primative that the later releases. The option to this would be to wait for 8 months+ and release only the final version.
Who knows...
-the first release might only include: fuel, timing and limiters.
-The second release might include the same as the first plus the ability to turn off CEL's.
-The third release might include fan settings, idle and shift points
-and so on and so on.
So, the reason why I asked the question: "what are you wanting the software to do" wasn't to sound like a dummy, but so I can prioritize the features that people are requesting and try to get as much included in the first release.

If this really comes out and it works, I think I might pee myself with excitement.

bascho

Don't get discouraged fastsvtss.....there are a lot of members reading this forum who are happy to have input into the development of a new product. I am sure that MazdaManiac does not mean to discredit you or your company, he is just looking out for our RX8 community......he is a serious asset to most Mazda ethusiasts.

I think that maybe the two of you should start over. MM meet fastsvtss........fastsvtss.....meet MM.

Now get this thing going!!!
