2003-2005 Cummins tuning

[chevycummins1]

Was wondering if efi live is capable of 2003-2005 Cummins tuning yet?? Or is it still in beta testing??

[2007 5.9]

Nope, not happening

[chevycummins1]

Why not happening??

[2007 5.9]

Efi has chosen to not support the 03-05 trucks. Focus is now on the 4th gens.

There are multiple posts stating this on this forum.

That's a bunch of b.s. for 2 years they said they were working on it, Cindy from efi live even said that. There are so many truck owners out there that want it.

They never said they were supporting them...Cindy said that it was on the development table and that they were looking at supporting them, but it was never promised.

Belive me I know it sucks...I have many many friends with 03-05 trucks that are now stuck with udc tuning,

I guess efi live isnt as great as everybody thinks. Its amazing that they can seem to keep up with the Duramax ecms, but can figure out the 03-05 cummins

All Duramax ECM's are CAN-BUS based communication. 03-05 Cummins is SCI which is Chrysler specific portocol. Two very different protocols and apparently more work then all of us think it is.

I know the industry has been hoping and dreaming of real tuning for the 03-05 trucks
