Uh, thanks ... :icon5:

I've just got the pro version of MazdaEdit. Look forward to playing with it when I get some time.

Anyone know where I could find stock hex files to download? I just wanna look around for now. Would be nice if we could get a community thing going.

thewird

That's the $10,000 question ....

You should have got enough from them to get you started ?

What is?
I did ask them if he had any stock hex roms but given its the weekend and the timezone difference, I don't expect anything soon. Anyway, I found a rom from an RX8 on the interwebs. I have confirmed it is from an RX8 by browsing through the maps but not sure what year or version.

A few things are labeled but for the most part, the maps are not labeled. I'll have to spend some time labeling them based on whats already known and what Cobb has already labeled for us. Then guess/experiment the rest because I think there's more maps here then Cobb had available to us. Anyone interested in completed definitions?

Figuring this out is gonna be fun. PowerFC's, Haltechs, Microtechs, and Megasquirts have me spoiled. The learning curve on this is gonna be interesting.

It's too bad I sold my RX-8 a few weeks ago and then decided to buy this lol.

thewird

the one you asked, but don't get yet ...

have fun

I already found what I was looking for so I don't know what your implying. I just wanted a stock bin so I could open it and see how the maps are laid out and how much of the definition work is done. I sold my RX-8 so I didn't have one to read the rom off of.

I'll be tuning an RX-8 in 2 weeks so we'll see how that goes :). I'll be working on the definitions in the meantime. Doesn't seem all that difficult, just time consuming.

I figured this forum had improved since Mazdamaniac was gone but maybe some of him is still around lol.

thewird

I have worked out all the maps that you might need - pm me if you need any help .

I sent you a PM.

Some things I have identified for differences between the Cobb and MazdaEdit. I did them to send to someone but since I did the work already decided to post here too if anyone is interested.

What MazdaEdit labeled as the Open Loop Gear tables would be the equivalent to the Air/Fuel Gear tables. MazdaEdit has put it as actual AFR while the Cobb was in lambda so in a way the MazdaEdit is easier to read in this case.

Now for the VE table things are different again between the 2. Cobb has it described as a percentage correction and use a map similar to the INJ map on the PFC. However MazdaEdit has some weird numbers which scale out the same but are nonsensical as you put it. Could probably get the programmer to update it. I attached the comparisons...

Again another comparison where they used different units though I'm not sure who is right in this case. The "Throttle Fuel Gear" by Cobb and the "Closed Loop Fuel Enrich" by MazdaEdit are the same map but went about it with different units. Cobb describes it as new lambda targets for throttle enrichment and is displayed as such. While MazdaEdit displays it as what appears to be a % correction which would match the way the aftermarket ECU's do it. Which is the correct method, I'm not sure. Again I attached images to compare.

And last comparison, the "throttle duty cycle" in the Cobb which seems to be the "Th?" in MazdaEdit. This is a map of throttle position to throttle body position but MazdaEdit appears to have the scaling better as his max is 100% while Cobb's was 83%. They describe it as...

"The requested torque values indicated how much or little to open the throttle. The requested torque is a function of throttle position in parallel tables “throttle requested torque A, B, C” . These tables can be altered together to adjust the sensitivity of throttle position to produce a response in engine power."

However, I don't see that Throttle Requested Torque map. Anyway, here are the maps again...

Edit: Fixed the correct throttle Map for Mazdaedit

thewird

After realizing the "Relative Throttle Plate Position" from Mazdaedit wasn't the Throttle duty cycle from Cobb, I corrected it with the right map above. But now that begs the question. What is the "Relative Throttle Plate Position? Relative to what? I also noticed the Desired Torque map. Can this be related to what the Cobb description was getting at but doesn't have the map listed? Why doesn't the Cobb have it listed? Maybe its available in the Pro version?

/\ Both those maps were incorrectly labelled as were a few others ....


Looks like you are going through the same BS i had to .... I was going to get the maps properly defined so he could have them correct for others but found him hard to work with and lost interest .

I assumed they were at least somewhat relevant to their descriptions since the Cobb does not have those maps. I guess that was a bad assumption. Have you figured out they actually are? Does the Hymee have any maps that the Cobb didn't have available?

I'm still waiting for him to get back to me if he had any stock roms so I haven't sent him anymore e-mails. But he does offer support for a year so I figure I'll use it while I can even if the replies are delayed with not that great english. I hope to get enough of it figured out to at least tune a simple ported N/A on stock injectors and then slowly figure out the rest of it.

thewird

They may have some relevance to the description ................ but I couldn't see it .


Hymee has pretty much All the maps .... as does Mazdaedit . There are a few that Cobb does not have that I have found slightly useful ...... but not many.

The basics are well known, but theres a whole sh-t load of them in there that haven't been figured out. The OE software is huge compared to what Cobb is altering/adjusting. How effective they are comes down to your understanding of what they do/how they interact with each other. Getting down to that fine level of detail will take equipment, knowledge, experience, and hard work. I suspect most of you are lacking in a few, if not most, most of those areas

As far as I'm concerned - there are certain maps that are essential for tuning an FI engine and cobb found all of those . Was not too hard to find them on Mazdaedit - just frigging time consuming.

Working out the rest is pretty much an academic exercise. ........... IMO

Attitude like that is why the growth of knowledge on this forum has always been lacking. Of course they're are smart people here like anywhere but the general attitude is, "if I know something I figured out, I gloat I know it but will choose not to share". Learning is all about experimenting, especially when your trying to do something outside of the box. Years ago I looked into purchasing the Cobb Pro Tuner. While the price was a turn off, it was the monopoly bullshit that ultimately turned me off from it. Why does one need a separate ultimately functionless Cobb unit for each car when we just need to reflash the ECU? Then I looked into the Hymee and it was the same shit but worse with their hardwareless VIN tokens. Again I moved on. Now there is a tool that can be used by anyone on any car so this is going to promote interest and hopefully provide more development in tuning the stock ECU. I say that because the developer is going to open the RX8 in the personal version at some point which is much more affordable. Which hopefully will generate a lot more interest and development in the program. For now I will just learn what I can and try to share what I can for any of those that are interested, the same way I do on 7club. I've even full tuned cars for people I've never met in person without getting paid for it.

Anyway moving on...

Realized I had a stock map I had downloaded weeks ago and then forgot about it. I believe it is from a 2006 Europe 6 speed car. Since the previous map I posted is identical to the Cobb one I have, I'm going to assume its from a 2005 USDM 6MT. Are the 2004's the same, map wise? I uploaded the map.

Anyway, first thing I noticed was there were a lot more maps. 629 maps vs 513. That is an extra 116 maps! Timing appears to be similiar at first glance but the first big thing I noticed was the Open Loop fuel targets are a lot leaner in the 2006. I wonder if that is a Europe only thing or if the USDM's got that as well, would need to get more base maps to confirm.

Here are the maps for those interested... First is USDM and second is Europe...

This subject is at least as half as old as the forum. Is it my attitude or your lack of experience in the obvious? My contention is it's the latter.


Ps: oh boy, you posted a fuel map. The question is, do you know which one?


.

I don't understand why you are so negative. Maybe its how you get your post count up by going back and forth with members.

Um, what kinda question is that, it is the easiest map of them all. It is the target fuel map before fuel trims for gear 5-6

thewird

Stop reading negativity into an honest assessment. If decoding hex was easy the whole thing would have been out a long time ago. Only a few people actually figured anything out. The rest used their work to get to the same level, but then obviously hit a wall once it all falls on their shoulders to do actual development work ...

Did anyone ask for your opinion? Like seriously, why are you even posting in this thread? Have you purchased Mazdaedit or even seen the software? Do you have nothing better to do then to sit at your computer and make useless posts? You mind just moving along, there is nothing for you here.

thewird

This is a public site and anyone having an interest or opinion are free to post anywhere on the site. As long, that is, they are not being disruptive.

lol nice

She can flash me any day.

IIRC, nope. There were some variants in the early days. Additionally, some (hopefully most) 04/05/06s have had the MSP-16 dealer reflash done, others, not. The dealer should know from VIN records if there's been an official reflash done on that car.

looks like it's safe to say that the gestapo shutdown thewird. way to go guys.
