I never got a clear answer on this one. When the AP downloads the original map off your car, can you actually see the codes of the original map or do all base maps have to come from Cobbs and you have to go from there?

Thanks

 

When I installed my AP, it downloaded the stock map onto the Cobb. When you sync your AP with your computer, and you have Accesstuner, the map that opens every time Accesstuner opens is the stock map.

 

Is it the stock map off your ECU or the stock map off the AP (reason being in case there is a new flash)

 

When you get the AP, you usually get a map on it from Cobb - if it didn't, you can register for Accesstuner and they will provide you a "stock style" map.

However, when you open Accesstuner, you still have to load that "stock style" map to access it, while the map that opens with Accesstuner is the "stock" map. It's confusing for me, and I'm not too entirely sure. I'll take a quick look tonight when I get home from work.

 

No, the one that shows up in Accesstuner is a stock "STYLE" map. You cannot directly edit your factory map.

 

That's what I figure, thanks! This is one thing I hate about the AP, it is so secretive and protective that it makes it hard to check things out before you buy!

 

What is there to check?
The stock "style" calibration is the most current Mazda flash.

I'm not sure what you mean by "codes" - the DTCs are the same for all flashes (and are reset when you reflash) and the mapping is the same too. Only the actual data changes.

As PCMs go, the RX-8 doesn't actually have that much data in the ROM - a typical reflash is only about 6 k bytes.

 

With all the flashes Mazda put out, is the stock style map really the stock map or is it something similar to the stock map? That's one thing I want to find out.

 

Does it matter? You're going to be changing the map anyway.

 

There have been no significant changes to Mazda's fuel and ignition mapping since the engine recall two years ago.

 

The oil metering map, not the fuel/ignition mapping. I am more concerned about that

 

I'm not sure I understand your concern.

If you have the AP, you can make that map anything you want it to be.

That said, Mazda hasn't changed anything in the OMP map since 2006. (Though the 2009+ models have an entirely different setup.)

 

So is it safe to say that the AP map is the same one as the latest Mazda map of the 2004-2008 cars?

I understand you can change everything in the AP, but there are certain things you really don't want to touch unless you have the necessary support for it. The control for the oil metering pump is one of them. How would Joe Schmoe know how much oil to inject into the motor, you are basically hoping that Cobb supplied you with the correct data! I really want to find that out for sure.

 

Wait.
You want to install an AccessPORT and then leave everything the way Mazda set it up - completely stock?
That's just ridiculous.
First of all, changing the fuel values is FAR more "dangerous" than modifying the OMP tables.
Second, you can only go up on the OMP for the most part and MORE oil isn't going to hurt anything.

I am failing to understand what you actually want the AccessPORT to do for you since you want everything to stay the way it was on the N3Zx or N3Mx calibrations.

 

Can you change the OBD11 readiness test data?

 

Yeah - drive the car! lol

I don't know if altering the items on that list will change the readiness flag. It might, but I can't imagine a scenario where it would be necessary.

 

he wants to pull the entire stock calibration from his PCM and then modify it with AP software. Or at least he wants to pull the Stock calibration and compare it against Cobb or your calibrations to see if things like oil injection have been modified. basically it sounds like he wants to be able to look at any calibration file that is in his pcm.

 

Oh well.

 

..

 

It seems that enough people want the actual PCM ROM data over a generic replica that it's just a matter of time before someone steps up to the plate and siezes the opportunity

 

I guess.

I have SW-N3Z2ET000 on my desktop. There isn't anything particularly interesting about it - its exactly the same thing as the Cobb "Stock Style" calibration.

 

zoom44 is right. I just want to see what the stock map looks like and make adjustments from there. This is not to say other maps are wrong or bad, I simply want to look at that use it as a reference since that is usually the safest map.

Changing fuel ratio is dangerous for someone who had never done it, but it is not exactly rocket science once you understand how the whole thing works.

 

Well, the "Stock Style" calibration IS the OE calibration.

And, if you think altering the OMP values is dangerous, how can you make a statement to the effect that changing the fuel values is not rocket science?
It is immeasurably more difficult and error-prone than the OMP!

 

You can monitor your AF with exhaust temperature and oxygen sensors and other parameters. You can't do that exactly with the OMP. How are you suppose to know how much it should dump in, at what RPM and at what throttle position without a starting point. My car is mostly used as a track car, I just need to be extra careful and cautions about everything that goes into the car. I am not saying anyone's tune is bad, I just want to see it for myself to understand it better.

 

Well, you can start by reading Yamamoto-san's books on the subject.
Then the SAE papers.
Then look at the Mazda OMP tables.

That will tell you all you need to know.

If that is insufficient, I'd suggest leaving all the other tables alone as well.
