First and foremost please forgive my ignorance on this subject. I am working on a ram jet 383 and am trying to get my mefiburn software to make it run. I have tried several things to no avail. I can get the car to run if I shoot carb cleaner into the intake so I know there is spark. I am hoping someone can point me in the right direction. Currently I am having problems with the checksum and have no idea how to get past that either. Do to uncontrollable issues the original programming had to be cleared from the controller due to password problems. Please help.

Thanks

 

I have seen a couple questions on the MEFI controller on here.
Try searching for the threads using MEFI of Ramjet maybe.
