Msd atomic efi ls

[DLW]

The MSD Atomic EFI LS system does not control the transmission, it needs a stand alone controller for the trans. It also does not come with a fuel system like the pump, filters, hose, etc.

The ECM is integrated into the fuel rails, and there is a small power module that has to mount somewhere. You will learn much more about the system, what it does how it's wired, and what it supports by downloading the user manual from MSD. There is also a nice video showing the complete install on the MSD website.

I do have this system but have not installed it and not sure if I will for a while as I don't really need it at the moment. I got it on sale when the price was like $1600 a year or two ago and have not seen that kind of deal since then. If I were to throw down money on a system today, I would probably go the Holley Dominator EFI route where one box controls engine and trans, plus has all custom tuning abilities along with dual WB setup if you want. Gets up into the $3K+ area real fast once it's optioned out.
