Default Mefi 4 Tuning

Does anyone know where I can get tuning software for a GM MEFI 4 module?

Software is called Ingenius.

For any generation of MEFI, MEFI1, MEFI2, MEFI3, or MEFI4, you can use this package:
www.mefiburn.com
These are great controllers and are used widely on boats and sand cars, and the Ramjet 350 and 502. The problem was there was not a widely available software package to tune the MEFI. The Ramjet 350 and 502 tunes as they come out of the crate are not optimal, but they can be tuned.

couple years later...

i found this thread searching for harness/MEFI ecms. We have a 350/330 crate motor and looking to go with the Ram Jet EFI. Are there any new alternatives for the MEFI? Any wiring harness's other than from GM?
