Tuning a 6.7 with a 5.9 Ecm

[2007 5.9]

maybe I should of specified but this is a dedicated pulling truck a 2nd gen dodge converted to a 6.7. So it needs fuel to 5000 rpm. 6.7 ecm only get to 3200 right now I believe.

You are correct...the CMB849 is your only option at this point for full fuel over 4k.

Thats what I figured so thats why I told my buddy to do the 5.9ecm. Les and idea if they will ever get full fuel out of a 6.7 yet

[2007 5.9]

It's not on the radar and I don't see it being so for a while

Thats ashame but I guess with the bigger motor rpm isnt as much a need. Because to make the power you dont need all the revs unlike a 12v where you need a boat load of rpms.

[2007 5.9]

Actually for the 6.7 you need rpm to keep the rods inside...big low end torque and limited rpm with big power will lead to ejection of the stock rods if the tuner isint careful.

IM currently working on pushing that CM2100 over 3900rpm on a pull truck myself, just gotta find those limiters.

Keep up the work. I think we all want to see 5200 RPM one day on a 6.7

[tylerltr450]

True true. good point les

[Mitco39]

I just need to find the time to dig around. If I get it ill post it up here.
