OK it's usable. page is here http://sr-ix.com/PROJECTS/MegaJolt/index.html , with pointer to my github page for download. its not packaged well for non-programmers but it's just a Processing sketch so shouldn't be too bad. i'm not a Java programmer and so it's not pretty. a few issues with initializ...

OK! silence! lol

so i have it substantially working: discovers serial device, reliably fetches MJ data conservatively, via a state machine. gets advance bins, bin labels, etc from MJ. saves to file, loads from file, and it loads the distribution Windows tuner files fine. real-time display of runtime data (RPM, load ...

i have it working on the bench, with a really crappy MJLJ simulator. easier than sitting in the car working on display crap. i know fairly well how the MJLJ works, but i have some questions: **** expected serial communication behavior: what should i expect/test for regarding response times, delays, ...

MegaJolt linux tuner program anyone?

i'm a happy owner of an early MJLJ v4, installed in my rambler roadster. solved all problems and opened up the engine. i recommend MJ to everyone. my one sore point is that there is only a Windows version of the tuner program. i've begun coding a tuner in Processing so i can use my little linux lapt...

is the old KEYSPAN usb serial adapter still supported?

i've been using my MJLJ for some years now without troubles. i need to redo spark maps after a major build, i went to drag out the Keyspan USB adapter that i've been using since the Stone Age (or at least Medieval times) and the MJLJ tuner program doesn't like it. "timeout reading config data&q...
