Hmm.. Charles you brought up a damn good point that I think no one has thought of.. why who the hell knows.. the PC for the tranny... would be easier to alter that one would imagine than having a custom converter built and installed. Hopefully Mazda was kind to us and made it simple as sin. I just wish they made 4th gear (in the 04-05 models) actualy useable instead of a useless cruising gear. That and a related question.
Would our speedlimiter be contained within the tranny PC instead of the ECU. We are limited to 124 (or so I'm told hehe...) so if we Auto owners could get rid of that limited omfg I'd be happy!! :rock: |
It is 124....before I had the mt I drove a 05 at....and even going down hill I couldn't get the car past 124....would make power up to it...but then wouldn't go any faster...or was it 115 I am thinking about.....either way it was limited

I wanna find the engineer that came up with this wild idea of making our cars ECU so damn fuquing hard to crack and drag him out into the street and shoot him. Mind you this will be after he hands me the magic key code to unlock it all lol.. I dont understand Mazda's application of the speedlimiter on the Auto's when the MT's dont have 'em. And no I aint gonna buy the "cause its a A/T thats why it should be limited" bullshyt responce either since to me its a cop'out. I heard that Moon at Pettit was looking into eliminating or atleast fooling the ecu via Int-X or another program 'cause he himself owns a Auto and has the Pettit S/C on his car and is sick of the 124 speed limit while hearing of MT's doing 150+

Making the ECU easy to program and to have easy tools to re-program the ECU, just helps Mazda overall and helps all the people driving Mazdas. Custom torque converter or Auto tranny PCM flash... Charles brought up some really good points. Re-amemiya had a project to create a custom torque converter for the RX-8 Auto, which should have been completed or close to completed by now. The R-Magic guys in Japan, were doing and knew about a lot of "funky" things being done to RX-7 Autos. Since the RX-8 inherited its Auto tranny from the RX-7 than there may be some good info. there. I will fish around for information from them. But, it may come down to good old American ingenuity in the end to "fix" the issue. Just like in the case of the SC and turbo for the RX-8. These guys make trans-brakes for dragging - http://www.fbperformance.com/NewSite...nsmissionID=92 The thing is to find a solution that allows you to use your auto RX-8 as an everyday driver and launch at 3,500 rpms or above. If you could launch the RX-8 auto at 5,000 plus rpms, without smashing your auto transmission or doing a neutral slam, than that would shut up a lot of people that dog autos. Another point too, is that the Auto RX-8s have a torque advantage over the manual that is not being realized/seen due to the stall and lower rpm launch issue. |

Racing Beat could easily get rid of it, and boost the power a bit, but they've already decided the AT isn't worth their time... |

Edit: all of this is for the 4AT, as I know very little about the 6AT. Really I don't know much about the 4AT either :) |
After further research I should ammend my previous statement. I think it's in the RE4 family. Nissan uses it as well it appears. The RE4 gear ratios don't match the 4AT rx-8. The 4EAT's do, however, but I thought that was a old transmission. Turns out, I don't know anything :wavey:.
Here's the gear ratios for the 4AT 8, maybe it'll help people searching for info: 1st: 2.79 2nd: 1.55 3rd: 1.00 4th: 0.69 I'll keep digging, maybe something will turn up. |
n charles found out that some suspension components r also made by mercedes n some parts from mitusbishi......all new cars nowadays r all put together by parts of different companies n the reason why is simple, CHEAPER on parts costs.

Well the internet sucks...information roadblock. I popped off an e-mail to Trussville Mazda, we'll see what they say.

Ok, I just went to the track, I messed up, my car limiter is also 124, the 147 was downhill, so I guess that would be why, as of currently, I am seriously fund-limited, but I do want to get rid of the damn thing, so I would like to ask you whether the e-manage piggyback can do the job or can I buy like just a limit-destroyer type product?

mine came with a dunlop GT racing tire.....thats for the 17" wheel I think......
and as for the speed limiter.......I been searching around and some products seem to beable to disable it....but it says for japanese cars....IDK if it will work for the rx-8 |
the tire ratings are in the instruction manual in the car, look in the back. my tires are stock and are rated to 149. sooooo i dont really think that the government would say that the car can only be limited to 125.
|
same here........149mph.......so screw da limiter.........
btw.....I was thinking of buying this http://www.racerwheel.com/sard-62301.html and see if it works.....thoughts? |
I'll just wait till Moon at Pettit or someone else finds that magic line in the code and eliminates it (or rather block it really), soon after that I'll buy that piggyback ECU from 'em since it will be then worth it!! :rock:
|
I see.....I asked the seller...all they said was......"it "should" work since mazda rx-8 is a japanese car right?"
.................. |
im curious to know if the cars are limited because there made in japan. does anyone know if the japan cars are limited too?

.................. In fact, the old version of JDM speed limiter defencer does not always works for the newer car models using CAM BUS communication in ECUs. For example, the SLD series (by HKS) for RX8 has three versions ( III-Z1 for 6 MT without immobilizer and DSC, III-Z2 for AT without immobilizer and DSC, III-Z3 for 6MT with immobilizer, 4AT with immobilizer but not DSC). The seller surely has no idea of what he's selling. |
