my fairly ancient MJLJ died today. its been in service since 2010 or 2012 (don't recall). it's running 4.0.2. it died while carb tuning; highway cruise speed suddenly got very pingy, and since i had been leaning the carb out i went in with the tuner program to retard spark across the board for carb ...

is there an Apple Macintosh version of the tuner program? Is it really windows only?

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...

i have one now, mostly working. i've been posting in the "General Q&A" area (to thundering silence :-) i wrote it in Processing, which i don't particularly like (but in fact i dislike writing graphical desktop programs to begin with, lol) so it will work on win, osx, *nix. it does seri...

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 ...

oh and what are the version command return values? I assume v4 returns "4" as major. but how do i use it to indicate compatibility? will the new /E return major=4? is there a map of features vs. versions somewhere?

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, ...

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...

all i needed to do was sacrifice MORE chickens, and the $DIETY was appeased and lo! it works. umm, that plus install configurator 4.0.2. not 3.x the problem is that when i google "mjlj tuner program" i was taken to the 3.x download page, https://wiki.autosportlabs.com/MJLJ_V3_Downloads . m...

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...
