Finding V300 93 Octane V3.2 Smart-Disabled Map for 2005
What I mean by rewire is change the input / output relationship of the maps to bypass the smart maps. At that point you can delete the smart map as it is no longer used. That said this is perhaps more advanced than most people will want to get into the Xede and Xmap.
An alternative is to use a V2 map and convert it for V3. If you refer to the version two section of the web site you will find 2005 maps for stage 0 and stage 0+. There is nothing wrong with these maps and all of us used them for years prior to version 3. When version 3 was released we converted them for use with version 3 (prior to the smart system release).
The version two maps include only four maps (tables) known as maf, crank, knock and boost. One should note that the boost map is sometimes labeled as unknown.
Xmap will convert the V2 map data to V3, but requires manual intervention to change the load variable. Here is the process posted by Shiv in the past with a few edits to bring it up to date...
I think you will like the stage 0+ V2 map. My car ran for over year with that map with overall flawless performance.

In order to use V2 maps with V3, they have to be converted. Basically, you'll need to define MAFin as the load variable for all the maps. Takes 20 seconds to do so here goes:
3) Open up Xmap and then go to file and open the desired Xmap v.2 baseline file from website. You might have to select "View All XEDE Map Data Files" in order to see them.
4) The tables will all pop up.
5) One at a time, right click on each table and select "Edit this Map". Towards the bottom of the page, you will see "Load Variable" and it will be set to "AN0in" (Analog 0 input). Change this to "Freq0in" (Frequency 0 in). This is because the EVO is unique in the way the MAF sensor is frequency based and not a more standard 0-5 volt sensor. Do this load variable change for all the tables (MAF, Crank, Knock, Boost/unknown).
6) Go back to the MAF table and go to "Edit this Map" again. Set the "Input Variable" to "Freq0in" and the "Output Variable" to "Freq0out". This is because the MAF table uses MAFin (Freq0in) as a Load variable (see Step 5) to modifiy itself.
7) Almost there. Now, go to "Features" and click on "Miscallaneous". Click on the "Use log-based scaling for freq. based MAF".
8) Now save the map under a new name.
That's about it to get the ball rolling.
Any questions? Fire away...
Cheers,

Damn, I had to fill up for the first time since coming to Tulsa (only for 5 weeks thankfully), and I was sadly disappointed to find 91 octane. I guess I'll be driving like a grandma until I get back to Texas!
Who knows, maybe by that time Shiv will have a v3.2 map for the V300/subzero on 93 octane. Besides, I'm not even familiar with the software yet so I doubt I would be able to go through the above steps right the first time.
Thanks for the info though!

I didn't check the link, or lack of a link, on the V2 web page.
Please study the map file that I attached in comparison to the '05 smart disabled map. There are two primary differences you should be looking for. First otherwise unused smart maps are deleted. Second the timing and fuel map outputs are no longer connected to user variables. They directly drive the Xede's outputs in an identical manner as a pre-smart map.
It is educational to draw out the linkage (input and output) between smart maps. There was a thread / contest on this back in the July time frame where there is a nice example and figures. Reading that thread should make this clear.
It isn't clear if the older knock attenuation scheme should be used for a '05. Thus a map without this feature is also attached.
By the way I don't understand why stage 0 and 0+ has been less that fully supported with the introduction of the SMART system. On the other hand I have found that the stage 1 map runs well on a stage 0+ car for street use. For road racing I always would run higher octane for protection.

My stage 0 plus map was right at 11:1 AFR. The stage one map pulls ALOT more fuel out.
Are these maps 05 stage zero plus?
Does anyone know of a basic manual for XEDE or the software? I guess I'll just look around in the software some and look for that thread that freedom mentioned... honestly I feel like I'm looking for a place to get started so to speak rather than just jumping headfirst into the middle of it all...
Realize that the difference between stage 0+ and stage 1 is resistance to knock via the cam gears given that they help to reduce exhaust gas reversion.
The maps that I posted offer the structure of maps that existed prior to the smart system introduction. That said I am not aware of a '05 stage 0+ fuel / timing data set. Thus all I could inject into the map was the stage 1 data from the '05 smart map. (I have an '03 so any data I have doesn't count.)
Here is the thread I cited above that explains the input/output relationship possible with the smart firmware via user variables,
https://www.evolutionm.net/forums/sh...d.php?t=147888
To be honest the thread cited, as well as Shiv's older Xede tuning document and the newer smart document represent the best information on the Xede. The files are too large to attach, so I'm not sure what to say other than search for them...

Cam gears change the entire fuel curve. Changing the fuel curve affects overall timing.
A car with cam gears and a car with stock gears are DEFINATELY going to need different tunes. You can see this in the 03/04 stg0/1 map differences.
Odds are....if you have a stage 0+ and are running a stage 1 map.....you are on the bleeding edge of a safe tune if not already unsafe.

True, but the real reason that the gears were introduced by Shiv was based upon trying to fixed a knock problem on an individual (problem) car that was on his dyno.
To be quite honest I have a huge amount of data logged by this point with the stage 1 map on my '03 under 95+F to 15F conditions (in the last week), as well as varying loads. It isn't clear at all that the words bleeding edge applies. Shiv's tunes are simply not that close to the edge in the first place.
I should also add that the words I received are "many stage 0+ cars do very well with a stage 1 map". This is to imply that some engines have better knock resistance due to manufacturing differences. On the other hand your engine might not or you might not want to find out by testing.

Well ..... If you look at the differences between the stage 0+ map and the stage 1 map they are pretty large. Personally I cant really say I believe the a few tenths of a degree of timing will make much of a difference if any at all. On my 93 stage 0+ map the max timing being pulled is point nine degrees. That is about useless.
That being said....If I am a stage zero car running a stage one map and then I convert it to a race gas map by zero'ing timing and removing even more fuel.....I dont think I would feel very safe doing that.
In the end it all comes down to this...... I paid $1k for a computer that is supposed to support multiple "stages" of modification. I WANT THE MAP FOR MY STAGE OF TUNE.
