It all just stopped on me!
I was on my way to the supermarket and it wasn't feeling well; down on power and very lumpy in the mid range.
I stopped at road works and so did it and refused to start again. Luckily I still had the old ignition in bits in the back and swapped that back in again in ten minutes and got to do the shopping after all. Hooray!
Now I need to start trying to get MjLJ back up again. I'm wondering if I've lost the VR sensor. It's probably just poor wiring somewhere.
The only thing I changed was the carb setup. It was horribly rich and I turned that down. It seemed okay after that but kept stalling at idle - just needed the idle screw turning a bit I think although I never got around to it. Can you starve a Megalost to death (just joking)?
I'm not expecting magic answers from anyone, I just fancied a bit of moral support.
ARGH!

If it stops completely it's
If it stops completely it's an EDIS problem - as you know, you should be able to run the engine without the MJLJ even connected, since you get a static 10 degrees BTDC from the VR/EDIS combination if no SAW pulse is ever returned to the EDIS.

You have my moral support as well.. I poorly engineered a way to attach a steel trigger wheel to a fancy aluminum underdrive pulley.
Well, the bolts attaching the trigger wheel let go all of a sudden when I started one of my Autocross runs. It bounced around the engine compartment a few times, dinging some of my oil lines (good thing they were stainless braided!) before shooting out the back of the car!

PHEW.....
Well, thanks Martin and Brent for the moral support. It did the job.
I found two loose wires. One was the power to the MJLJ box which I had moved into its final position the evening before. I must have pulled the connection loose and it obviously wasn't well soldered in the first place. An object lesson for me in the value of tinning things properly first.
That would account for the poor running observed before the breakdown.
Then, the power connection to the coil pack had slipped off the spade connector on the fuse box! I'm not very happy about that. I've given it a squeeze and put it back on.
Coincidentally, when I was putting the MJLJ in its final resting place, I also took the time to fiddle the carb and it was running very rich.
So today's the first day I've run with the proper map and a properly set up engine and I am totaly bowled over! It's incredably better than before. Smoother and faster and....the dream of all Landrover owners, quieter!
By the way Brent, I'm supposed to be phoning the tech' editor or LROi magazine and aranging to meet him about doing a feature article. I'll let you know how we get on.

What's it worth?
What's it worth to mention yours, 4600cc?
It was yours...as it happens. Mostly by accident as the first PC I got talking to the MJLJ didn't have Java on it at the time so I used your native app.
I rather like it though. I've yet to start trying to tune beyond the basic so I've had no recourse to the logging/flagging function yet. The only question I have about it is, is there a limit of 59 in the map bins? I was trying to put 60 in but it kept turning into 59 while I wasn't watching.

Worth? Worth as in $$$$?
Worth? Worth as in $$$$? Lol. $0.00..
I want credit. Because I'm greedy.
My picture in the magazine wouldn't heart either, but is optional, and man I have some nice pics of me and my mustang. Software has a license agreement, which addresses the press publications, it states that publisher must get approval and credits must be given. Which basically is a mechanism to guard against publications that are willing to show or mention the program without giving an appropriate (or incorrect) credit to the developer.

Well, what they want is a sort of photo workshop article. Lots of pictures of how the installation is done etc etc.
There may not be much room for detailed discussion of tuning or software anyway.
However, should I mention your stuff, 4600cc, what do you want said to satisfy your licence.
And Brent, do you have any similar restrictions or are you just happy to get the publicity? I would, obviously, acknowledge everybody and everything anyway. Are you happy that the article be written at all?

would be nice if your
would be nice if your software was actually finished and not a 'preview' or alpha or beta or whatever you want to call it,
Well, between what life
Well, between what life throws at you and the fact that I don't actually have a megajolt unit installed on my car now, it's very hard to do. Right now I don't even work on it, I'm working on a megajolt simulator now, which will aide developers in creating good tuning software.
The latest version requires just a few features to become a version 1.0. Most of those are just to keep me sleeping at night, for what really users require it needs an options editor, no function page cycling, good program icon, registered file types, event driven data acquisition, and that's all. That point reached, and any further development is just a feature enrichment. I lost most of my interest in programming tuner when I lost my car with megajolt installed, the only thing that keeps me going are 500+ users who enjoy the program.
When I started the project it looked like it would take about a month or two, and it should have if I actually spend time on it every day. But reality kicks in when you least expect it, and I didn't get much time with it at all, maybe a few hours a week, think 40 minutes on weekdays during lunch. Then from August last year to December last year, and February this year until now there was absolutely no development. The project reached a critical point by now, where extensive testing is required, this simulator program which is about to get released will satisfy testing needs, and a full version will follow. With full version should come a new look too. The MJCMSIM simulator which is about to get released is just an indication as to how new program will look. The structure of the program that I created allows easy and simple development of new features, and thus it should be very quick process.
The goal of my project, tuning software for megajolt, call it whatever you want, is to be the absolute best that there is out there. It might have a few rough edges at the moment, but based on what I've seen out there, I'd place it in top 10.

Official Position
Robert,
I'd love to have the project featured in a magazine. For me, only the common sense requirements: no misrepresentation -i.e. give prominence to the source of the project, i.e. me, (Brent Picasso) as the project owner, and the project's website address (http://picasso.org/mjlj )
In light of the significant project contributions, namely Al with his excellent tuning software, it's also worth noting how this project is structured, as it may be non-obvious to some.
The project's *software* (firmware/PC application) is licensed for use under the GPL. The remaining intellectual property, such as the schematics/PCB is provided only for reference.
The open nature of this project allows others to easily make their own, independent contributions to the project. For example, Al was able to examine the existing source code and use it to develop his own tuning application. Others have contributed test applications and alternate versions of the firmware.
As a result I think this aspect of the project should be empahsized in the article, and any major contributing pieces that are showcased have their authors called out as well.
Making it open also lets people examine the project details and allows them make an informed decision whether it's appropriate for their application, and more-or-less mitigates the fact that it's really an experimental ignition controller.
Furthermore, it creates an environment where I can get (hopefully) constructive feedback on the things I do wrong and right!
Hope this helps.
