Megajolt Lite Jr Tuner 0.1.1.1001_preview released

Post by 4600cc »

Well, here she is. The following is a PREVIEW release of Megajolt Lite Jr Tuner. The next generation of tuning software for Megajolt Lite Jr EDIS Controller. The delay of completion of this program have been enormous. I lost traction and my vehicle while using experimental version of ignition map, created using Megajolt Lite Jr Tuner. I had absolutely zero time during the week. Even from the start of this project I had to travel around the state, installing computers for Florida D.B.P.R.. So this project was basically written during the lunch and after work. By all means it isn't done yet! Enjoy this early preview version. A full version is coming very soon.

Some of the features in this preview were hidden, and will be available for your pleasure when full version is released.

I've underestimated the dire need of Megajolt Lite Jr. EDIS Controller enthusiasts of a new tuning application. And so this preview release is a response to the need.

Do understand that this is a preview version, and some quirks do exists. For example, I had absolutely no time creating the installation program. So this release is a simple file archive. Perhaps not all DLL files are included. If you get an error "Could not find somefile.dll" send me an e-mail with the file name, I will send you the file and include it during the next release.

Do not break laws while using this software.

INSTALLATION INSTRUCTION:

**EDIT Updated link to point to 1001, uploaded 1001 with more DLLs.


1) Save the file onto your Desktop
2) Extract the file into a directory (for example mjtuner_0.1.1.1000_preview located on your desktop)
3) Browse to that directory and double click mjtuner.exe
4) Cross fingers, if anything goes wrong e-mail me for immediate technical support

Using Megajolt Lite Jr Tuner is very easy. You can hold down CTRL and navigate across cells using arrow keys. You can also hold down SHIFT and use UP and DOWN arrows to rapidly increment or decriment values. Pressing CTRL or SHIFT by it self will select the contents. You can change engine load between throttle and pressue in General tab, you can also select the number of cylinders from the General tab, the default is eight. You can import or export old configuration files from the File - Import/Export menu. At runtime you can mark areas where detonation occurs using a space bar key. The ideal for tuning is to use a laptop next to the driver, perhaps strapped down in the passenger sit. Driver would then run the course, keeping a finger on the biggest key on the keyboard (the space bar), pressing it when detonation occurs. After a run adjustments to the map could be made using that information.

Megajolt Lite Jr Tuner supports default files. A sort of template file that is loaded as default information on every start or File - New. You can access the default file in C:\Documents and Settings\Name-of-a-user\Local Settings\Application Data\Megajolt Lite Jr Tuner\default.megajolt

Looks good, Al! I wasn't able to get it to talk to my COM port, but from what I could infer by the user interface it appears you have a lot of nice improvements there. The use of contrasting colors would probably useful in this situation, like outdoors where the screen can get washed out, etc.

Any plans on releasing code under a less restrictive license?

Serial works!

Post by 4600cc »

Serial communication was one of the first things done. It is tested, tested, and then tested again. If you can't get it working, then a) something is wrong with your system, b) version 2 of megajolt you using is not really compatible with my communication library. I'll post an mjsim.exe, try it with that, tell me if you still can't get it working.

Releasing the source code? or releasing the program under a less restrictive license? To tell you the trueth, I haven't given any thought yet to licensing.


MESSAGE TO ANYONE WHO CAN't GET PROGRAM TO COMMUNICATE

e-mail me with what you doing and what you getting 4600cc@superford.org

Post by 4600cc »

It looks like Brent have changed something between version 2.0 and 3.0 of firmware. So communication is not happening with 3.0 boards, but it is just fine with 2.0 boards. I am working on this issue now.

Correction: The V3 firmware

Post by brentp »

Correction: The V3 firmware has experienced *no* changes since V2- the primary change was around how the PIP signal was being processed, to accomodate V3 hardware changes. That is all.

Also- note that the java version of the configuration software is the same version (2.0.3) for both V3 and V2 controllers.

Rest assured, the serial IO is currently identical for V3 and V2 processors.

Post by 4600cc »

So, is it possible to get this sort of test from anybody?


1. Connect megajolt using serial cable.
2. Start up Megajolt Lite Jr Tuner
3. Select correct serial port from drop down menu
4. Click GetConfig

IT WILL EITHER WORK OR FAIL

When failed

1. Connect serial port 1 and 2 with cross over cable or virtual serial port driver
2. Start mjsim.exe and press space to continue
3. Start Megajolt Lite Jr Tuner
4. Select COMM2
5. Press GetConfig


IT WILL EITHER WORK OR FAIL


If it fails that means I'm wrong, and there is something with my program.


I could not get anybody to perform this test. I can do it on my computer using simulation software and a copy of brand new operating system, but I my system is down now. PSU blew up, 450 Watts, still not enough.

Post by 4600cc »

Aight. Mine don't work either, but mjsim works, humm. I guess something was changed between last time it worked and now. I'm looking into it. Another preview is coming right up, as soon as I fix this. Runtime display is gonna be a blast, I promise you.

I would try this as I have no communication with my board but I don't know what this means:

1. Connect serial port 1 and 2 with cross over cable or virtual serial port driver

If I can do it I will try.

Post by 4600cc »

Never mind.

I found the problem. And the problem is silly. Borland uses tricky memory management between different applications (DLLs and EXEs, etc). Basically memory model for applications compiled with dynamic RTL and PACKAGES is different from static. So, when you select a serial port (COM1, COM2) in the program, the program send rubish to mjcontrl.dll driver, and thus you can not connect.

MJTUNER is made to be compatible with dynamic RTL and UI LIBRARIES. Since I don't yet have (downloaded) installation program maker that scavenges which DLLs to include, I switched to static linking, and got myself into a major fuzz with this communications stuff. Actually RTL is dynamic, but UI and utility libraries are static.

So much for a smooth start. That's what happens when you don't take your time. I released a BUGFIX, replace communications driver and it should work.

Thank you for testing this

Post by 4600cc »

Thank you for testing this first preview release. Feedback from people like you is highly appreciated. You've done your job and contributed to megajolt project by testing this configuration software. Unfortunately, this release have been plagued with missing files and improper memory managers, and as such it takes a little more than your every day e-joe shmoe skills to get the program running.

But don't get this let you down, a new fully functional preview release is just around the corner!
