So I made mention of my MJLJ in a few threads as of late which has seemed to generate some interest in my build/progress (?).
A little back ground on me: I have over 10 years of electronics/electrical trouble shooting and assemblyexperience form both high school, and the Coast Guard where I was an Avionics Technician. This is why I had no problem assembling the MJLJ unit. However, I am not a computer guy and programming is proving to be a HUGE PITA. The build: MJLJ uses EDIS which is a Ford distributorless electronic ignition system. The information for this part is available at http://picasso.org/mjlj/ To use the unit you will need a 36-1 toothed gear for the crank and a VR sensor. I am including pics of my pieces. Here would be a good place to show your prowess in programming as I am lost. it seems that my USB--> serial adaptor is not working, or it could be the unit. More to come. Post pics here for discussion. Pics are of the toothed gear installed and of the pully with it mounted separate. Attached thumbnail(s) ![]() Attached image(s) ![]() ![]() |

You can use the curves you posted as a starting point. Note the SC curves only show the centrifugal part of the advance curve. The amount of vacuum advance is in addition to what is indicated on those two graphs. Also note that the RPM axis on those two graphs show distributor shaft speed....ie 1/2 crank speed
Im at work now, and dont have the resources here to check, but i believe that an SC had total advance of 30 @ 3000 rpm. You will also have to find the static advance your system has..find by using a timing light, cranking or running the engine with no advance added from the computer, and noting the amount of advance. This number is important, all timing is added to the base or static number. Im leaving work now... will continue later or tomorrow |
