It looks like your timing is falling off before it dies go to your Base spark in drive table and put 20 deg in it all tha way down to 0.60 and 15 below that. You can see on your scan the timing going from 19 on your high oct table to like 5 on your base spark table also turn off your idle proportional fuel table that will help alot. It also looks like it goes rich before it dies and the fuel trims jump to neg-5 but with a cam I think I would try the above first . As far as tha throttle cracker Vs RPM table I would not worry about that much it gets disabled at 3 mph and does nothing at idle.

 

Yes but it enables at >2 miles per hour saving it from a stumble. It will work

 

Looks like a good place to start.

 

Whats is the real problem a stumble or is it dying? the timing is at 5 deg just before it dies, should be 15-20, I agree slowing the cracker down will help some but I think the timing falling off to 5 is a bigger problem. Just my 2 cents. I had a g2 ligenfelter cam in a 6.0 with a mag and never had any of these problems and I had a 850 idle and 25 deg of spark at idle and my 02s oscillated just fine. It could be anythingI am only looking at the scan data.

 

No you are right Crash Dummy. I think you know something about tuning. I know I experienced what BigTex is describing.
Why did you increase Base spark in Drive tables? I know it smoothes things out some, but I'm just wondering if things were copasetic why touch those?
Oh ya where is that idle proportional fuel table. Are you HPtuners or edit?

 

I think Tex is using Edit

 

I know. I am too. It sux! Or well at least it could be better, but it does get the job done.
I was wondering what CrashDummy was using b/c I am trying to find that idle fuel proportioning table

 

I believe he is using HPT.

 

I don't think he's asking Tex.

I know EDIT doesn't have that table, dunno about HPTuners.

If you still suspect a vacuum leak, check the o-rings on the injector. That was my vacuum leak before.

Like the fuel presure regulator though ... use lots of lube on them.

 

Another good culprit.....Tex did tear that blower down (destructive guy that he is )
