DFCO after cam swap.
just trying to get my DFCO functioning again after my cam swap and wondering if someone could look at my settings and make sure they don't look ridiculous.

I'm ready to get to the track and see what kind of improvement the cam has made at full weight. Then I will probably go for a little weight reduction (skid plates and spare tire) to see what I can get it to run.

Thanks Rick. That's what I have done and I'm getting close to having it work the way I want to again. Now I'm slowly working on getting the idle nailed down so I can go back to an OLSD tune. AFR at idle in closed loop is good but when I go to open loop it seems to be all over the place.
Ya they are pretty similar. I can't remember is yours 2wd or 4?

Keep the MAF on it.

I'll give that a try. I just need to re-tune the MAF first, I had it turned on for a while and it apparently needs some work because my afr was not good with it. Oh the process never ends.

I'm really hurting for traction though. My rear end is stock with an open differential, 3.42s, and I don't have a set of d/r's
I'm curious as to what you run so I know what to expect. I'm hoping for a 13.xx when I buy some 4.10's and a true trac.

I would rather keep the DFCO. I'm not so much concerned with fuel milage savings as I am the decel function it provides. Greatly saves on having to use the brakes when out on the highway. Also if it is tuned correctly there should be no adverse affects to the drivetrain and the afr doesn't go "crazy" it does exaclty as it should and reads lean or my wideband will actually say "air" if I let it coast long enough. I almost have it working agian I just have to fine tune it a little to get it to work when I want it to.

Bigbadwolf54 had a ~13.92 with a similar setup as you before he went to the 6.0L.
His truck is ECSB 2wd and he had
about the same cam specs (I think it was a different brand),
pacesetter LT's/ory
4.10's and a tru-trac
WCCH heads
3400 stall
stock fan
stock intake
He was severely traction impaired on street tires so with good traction I could see 13.xx's out of your truck!
