Just got my dunebuggy runnuing on the MegaJolt however, it does not run well. It seems to miss at idle. As the RPM increases the motor smooths out. Also the software shows that it is idling at about 1000 RPM and 12 degrees of advance. My timing light shows that it is at about 20 degrees of advance. When i add more advance in at the lower RPMs it smooths out some, however i have not added anymore than 5 degrees. I am using the enclosed spark map.
I don't understand why the degrees of advance do not match what i am seeing with my timing light. And is this a good map for my motor?

Agree, you should first check what the EDIS default advance is. It should show 10 degrees- if not, you can adjust the trigger wheel to sensor alignment. Or, you can use the trigger offset feature in the Megajolt firmware (see the operation guide in the How-To link above)

it's nearing time to get the buggy out again. this year i went to an electric fuel pump and duel carbs. i also have replaced the Ford coil with a coil from Pantera EFI that he sent me because he wanted the defective Ford coil i found last year. everything seems to be wired properly however, the motor is only running on 2 cylinders. when i start it only the exhaust pipes on the 3,4 side of the motor get hot and it runs rough. the carb on the 1,2 side is getting gas. i have checked the spark on #2, it's there, just seems weak.
Any ideas, suggestions?
