MSD atomic EFI controller, extension cable and O2 sensor

[Erik Beckett]

These were extras I had laying around after installing 2 of these on two different cars. Troubleshooting with MSD and they sent me these as backups to try and it ended up not being needed. Open to offers.



Thanks, Erik

I’m putting an atomic efi in. I’m curious as to what problem you had and what ended up as the solution?

Mine ended up being something really stupid, once it was fixed it was awesome. Had to do with wiring switched 12 volt source. MSD would not respond until it hit 1500rpms. I cant remember exactly, but I thought it was O2 sensors bad but it was the 12 volt source. MSD techs were awesome
