had one area about 4000 that preignition was occurring so at 80 kpa on i backed off about 5 deg and that seems to have eliminated it. id be happy to post in the gallery soon and maybe post a map at the ig library when im happy with it. thanks again for all the help and advice. garth

by elimination, the stock coil was incompatible with the ford edis. replaced it with a ford cop and the missing is gone and engine runs flawlessly.

using mj on a650 single the load needle jumped around a lot- maybe to the point of not being usable. tried several different methods to snub the needle including an orfice fitting, sticking a q tip up the vac line. not much room for anything large like a canister on the bike. found a real small 1/4 ...

still having erradic firing on the mj, runs good and steady on edis. went back thru the testing and verifying and the only thing that doesnt check out is 12v between edis pin 1 (pip) and ground. its about 2v lower than batt voltage. about 3800rpm is where it starts then the controller tach starts to...

have been trying to change this from zero but when i enter another value, and either hit read or write configuration,and commit to flash, i will go back to the global controller window, and the pip level will be back at zero again. am i doing something wrong?

engine runs much better now. have set trigger wheel alignment at plus 5 deg., it was retarded about 1/2 tooth. have coil neg connected to pin 10. still a bit of popping coming from exhaust, perhaps some carb adjustment will help. software tach much steadier now also. thanks for all the advice.

yes, i have the coil neg connected to pin 10, runs better than on pin 12 and have taped off the pin 12 wire. did the cyl leak test with air and have between 10-15%, pretty well sealed so that eliminates valve lash. have opened the case, and checking the trigger wheel-p/u coil clearance with a feeler...

have not checked the wheel because its inside the case but will open and check. the edis coil out wire you mention, i had it tied to pin ten, then to pin 12 and it seem to run a little better. i guess the other wire is left disconnected?

tried the 12v auto batt, same result in operating, about 13.09v both batts, missfires idle to about 3000rpm on mjlj, idle to about 4000rpm on limp. both 12v supplies from same source also both grounds. have resoldered all connections on mjlj board to double check. also will check coil connections to...

have put both grounds at the same point, now also runs badly on limp, the same as with mjlj. the tach now ocillates between 2 points on the software tach and with the timing light running at the same time,the missing is visible in the strobe. it will still pop out the in and ex now wether in mjlj or...

maybe i havent searched the forum far enough but heres whats happening. assembled megajolt. had a trigger wheel made and used stock p/u because its inside the engine case and room is very limited. installed edis 4 per diagram using shielded wire 16 awg between p/u coil and edis and also between edis...
