Hi guys -

I just uploaded a new version of GMECM Edit. Thought I'd finally make good (at least partly) on my promises to get some graphing in place. =) Things are gettin' better!

Check it out: http://gmecmedit.markmansur.com/


Whats new in this version:

- Destructive actions must be confirmed during more than just app exit now (opening another ECU when current ECU is modified, for instance).
- various other bug fixes
- Graphing (finally)!!!

Some notes on graphing:

The graphing control was written from scratch. It's not the best, but it does the job. The graphing interface will continue to improve with age. I will continue working on it! You *will* find bugs. Please report them (kindly and with as much detail as possible). You can drag data points and see the results in the table grid. Changes are not saved until the "save" button is pressed in the table. Graphs open up in a new app window (meaning it shows up in the task bar) that can be placed behind the main application. Currently, you can only have one graph at a time open (opening another graph replaces the previous graph). The spririt behind this is that the workspace gets too cluttered with multiple graphs open, though this may change in future releases. If you have problems with data labels overlapping, etc, try resizing the graph (specifically the vertical dimension). This changes the font sizes. Closing the table that is being graphed will close the graph as well. You can graph compare tables, too. Simple click the compare button and then "View Graph."

- There is one outright bug I know in graphing, and it's only a problem in Win9x ... If you resize the graph (and even drag data points) a whole lot, the graph goes a bit wacky. Simply close the graph and reopen it and the problem goes away. Under normal circumstances this shouldn't be too much of a problem. I'm investigating it. This bug is a result of the general suckiness of Win9x, and you should upgrade to XP.

2D tables must be built within a column at this time. In array built in a row will not be graphed, but these are easily converted to columns by swapping the number of columns and rows in the ECU item definition. =)

3D tables cannot be graphed at this time. I *am* working on a solution for this, but the problem is not as trivial to solve as 2D (in terms of scratch building a control). Tunercat bought their graphing controls (Olectrachart). I don't make money on my app, so this isn't an option for me. =). Stay tuned (there's a pun there, huh?) ...


Whats Coming in future versions (time permitting):

- Compare graph will be viewable on same graph as another series.
- Auto ECU - allows you to specify an ECU to open automatically when a code mask is found in a bin.
- Inc/Dec from within the Summary List (pressing +/- will Inc/Dec the selected item)
- 3D Graphing

Known issues:

- Graphing bug in Win98 where the graph goes wacky after lots of resizing and data-dragging.
- Help file is greusome and incomplete. It, like this program, is a work in progress.

Here's a screen of a graph ... just so you can check it out:

Pretty cool, I was thinking about buying Tuner Cat next week, but I might wait until the 3D graphing is up and running. It is real similar to TC. I love the ability of dragging the graph. That was the reason I was going to TC. I think I am going to stick on board. NICE work, definatly worth the wait. Your the man! I do have one question, I am using the 1227730_8dm ecu file, under the flags it has "AFR options 1, 2 , & 3" and you check the boxes, could you tell me what these are? I think they are for VATs and such but I don't know which is which.

Mangus

no clue man. I'm a 6E guy.

OMINOUS_87

6e love!

Can you tell me what these might do please?

Well thanks anyway, I will eventually find someone who knows it.

Mangus

My understanding is that these numbers dictate where the in the "BLM Table" (if you will) the cells begin and end. There's a good explination out there of how BLM's and cell boundaries work (with pictures and all), but I can't find the link at the moment. I'll update if I find it. Meanwhile, search these wonderful boards. I'm positive you'll learn all you need to know. =)

The only reason left for buying TC is the "Real time" programming..............

explain...?

I have searched but not come up with any conclusive info that I can understand. PLease do update if you find the thread that spells it out.

Thanks.

Ok..

1. Hook up computer to car (romulator instead of PROM)
2. start program and car.
3. drive around
4. do changes in Tunercat and hit enter and drive on. No PROM change.....

This mean that you can do changes while the engine is running, when you hit enter the changes goes from tunercat to ECM......

Oh, right. Thats all xtronics. If they want to work with me, I'm willing to work with them. Nothing I can do otherwise. ;-)

(So, you're right ... good reason to buy Tunercat. Go that route).

99$+20$+180$ ...Hmm.... no thank, not yet.

I LOVE your program.......

ftp://ftp.diy-efi.org/incoming/BLMCells.exe (which is a self extracting archive containing two pictures and explinations of how BLMs work. Its not the explination I was talking about earlier, but its a starting point.

JPrevost

one word....wow
I understand the no 3d graphs, that's a bit harder. In the mean while could you just have rows or columns graphed out? That alone would be worth it and I wouldn't even care about a 3d plot.
As for the frequency of your updates, again, only one word....wow! Love your work, faster than TunerCat on my pentium 75 and that alone is worth more to me than it being freeware.

Mangus

That was more than one word (74 to be exact).

I've thought about doing exactly what you say there - allow you to graph a row in a 3D table. I think I will get this into the next version until I have a surface plot solution in place. ;-)

And yes, there are at least two great things about GMECM Edit as compared to Tunercat when it comes to running on older computers:

1) its tiny (can fit onto a 3.5" quite easily *with* a bunch of bins and ECU's). - related to this - it doesn't require any type of installation! Just unzip it and run it!

2) its written from scratch. No MFC overhead. No Visual Basic overhead (*ahem* [GMPCM] *cough* [Tunercat}). So its fast! And small! (there's a joke in there somewhere)... related to this, it doesn't require the MS chart/excel controls (that both the other programs require) ... which is where some of the speed is bled off with the other programs. No need to initialize dependencies (which is why it takes so long to open the table/graph the first time in Tunercat).

Really though, tunercat is a great app. It rocks. I have a lot of respect for them.

Stay tuned...
