Msd atomic efi ls

[izzy_Britton]

Is anyone using the MSD atomic efi for their LS swap? i never heard of this until just a few days ago and i have been looking for more info. I have read a few different websites and i have read a HOTROD magazine review that sounded good, but there is NO real tech geek info available on the system. sure it is self tuning and a laptop is not required but WHAT ELSE?

who is running this on their swap? how do you like it? would you buy again?

I am looking for some other more or less specific questions. for example:

There is a LS3 master kit, but there seems to be no info on the trans controller. Will the LS3 master kit with trans controller control a 6l80/6l90 or the newer 8L90 trans? or will the trans controller ONLY control 4l60e and 4l80e variants?

HOW LONG is the cord to the hand held unit? does the hand held unit need to be connected at all times for proper operation? The availabe info makes it sound like the ecu/ecm is 'integrated' into the fuel rails, is this the case or is there another ecu/ecm that needs to go somewhere else? or is this more like a self contained unit with a simple 4 wire connection?

This system sounds simple and looks good but as mentioned there seems to be little or no hard information available, maybe its just too new? it is also not a CHEAP system to run out and buy considering the lack of info.

I am not 'in the loop' and never will be with this stuff, but i would like to keep my options open. I have plans for several different LS swaps in 2018, i have already got my wire harness and ecu for my square truck, but other options might make the next swap easier...

Thoughts?

Thanks in advance.
