Which ECM to select on SCT X4 for Heartbeat supercharger install?
Not sure which ECM to select for a 2012 LS3?
Need to install the tune so that I can get started on the install.
Book has E92 as an example.
Not sure if this will pick it up automatically like the ITune2.
Thanks in advance for any help.

When I connect with the programmer it only gives me two options, 5.3 Silverado and 6.2 Silverado.
It does not show a corvette option, I can not download the stock tune so that I can send it to Magnuson to be modified.
Anyone use the X4 with the magsnuson?
How did yours work?
thanks

Magnuson sent me the wrong SCT the first time. Yours should be PN 7416M. It should have YOUR VIN: number on it and your SO# on it. I'm in CA so I need the CARB except number.

I went back thru the book and found the problem, I missed moving the cursor from continue to upload stock.
Default was continue. Will have to slow down a little in the future.
thanks
for the response.

You already have the Damper done then the hard part is out of the way. I have taller valve covers to clear the rockers so to get to the back two lid bolts I took the cover on the passenger side off and dropped the cradle even more that the shim to get behind the engine.
My tuner had me install NGK TR7IX plugs for the tune. The SC is heavy but I did not have anyone around at the time so I set it by myself, not really recommending it but it was my only option at the time.
All in all it was a good project and glad I did it. Steve
