Old software installation

Brian Ramsey · Post by **Brian Ramsey** » Tue Oct 16, 2012 6:48 pm

I have an old Megajolt which runs on version 2.0.3 MJLJ software with needs the Java COMM API installed and configured.

I've recently changed the carbs on my 1.8l Zetec silver top and would like to look at the map, but I don't have the software loaded on to my laptop. I can see the V2.0.3 software, but I can't find any of the Java software I need for the serial port support.

These are the instructions I had, but none of the links work:

[i]Install Serial Port support (Java COMM API)

You need to download Sun java 1.4.2 from the sun site – www.java.com.
You then need to transfer the following files to the directories shown.
These 3 files are in the commapi directory in the “Megajolt java stuff” folder.
For windows, download:
Java Comm for Windows.

- Copy comm.jar to c:\Program Files\Java\j2re1.4.2_04\lib

- Copy javax.comm.properties to c:\Program Files\Java\j2re1.4.2_04\lib

- Copy win32com.dll to c:\Program Files\Java\j2re1.4.2_04\bin
The megajolt software is a java applet. You start it by double clicking the MJLJtune – 2.0.3.JAR file.[/i]

Any help greatly received, keep it simple though, I'm no IT expert!

Hi Brian,

You probably want the version 3.0.0 configuration software, found here:

This won't require Java. Just install, configure and run!

Thanks Brent, that appears to have worked. Should I have any issues with Windows 7 and finding the usb/ serial cable on the right COM?

It *should* work, in principal. However, we haven't tested that version of the software with windows 7.

I'll let you know how I get on. Hopefully it will be useful feedback.
