Right now your BRAF table needs work. Once you are able to drive it without it stalling, you can tune the MAF and VVE. I just added a quick 2% to the whole BRAF table to see if this helps with...
Yeah, you can experiment with it. If you don't like it, put it back. You will be decelerating with little to no load on the engine, so you should be fine.
Try 1.2 first and see how it feels, then try 1.3. Graph was looking a little rougher than I thought it should be for 1.3, so I did things a little differently with 1.2. The graph seems to make more...
checking it now!
Get as many hits as possible in each cell. The more hits; the better the data. Just drive as you would any other day, only for a bit longer.
Same thing, flash, reset LT's, wait 10 minutes then start the log. This time; take the long way home :D

Once BRAF and fueling is dialed in at idle, you will not have any issues. If this one is any better, try to get a longer log to let the trims settle a bit more. I Added just a bit of BRAF. 146703 Are...
See if this one will idle.

On this one; reset LT's and take her for a spin. Drive 10 minutes then start the log. Log for around 20min.

Have you found the sewing machine noise to be from too long or too short of pushrod?
I just double checked the tune you had posted and it in fact shows me 7000rpm. I think it may be user specific?? idk.. BUT you can click on where it says Engine Speed and select for it to show...
I just looked, your VVE maxes out at 7000rpm
Awesome. Thanks for chiming in Ed. His Camshaft code is a P0340 as stated in post #3. I took around 25% fuel out of this thing and i did add some BRAF but only at idle and lower. Honestly, I am not...
It's possible id say; however, I am not familiar with the 5 to 3 pin conversion. I would at least check the wiring connectors to make sure there are no loose wire connections there. You can create a...
See if this helps. 146579
You can reset LTFT's, no problem there. And no worries; we had this looking pretty good with the maf-vve tune. Not sure what happened to throw fueling off that much unless it was the MAF fail...
Add these channels to your scanner: MAP, DYNAMIC AIRFLOW, VOLUMETRIC EFFICIENCY AIRFLOW, INJECTOR DUTY %, INJECTOR PULSE WIDTH B1 & B2, AND CYLINDER AIRMASS. This should get some useful data for you....
Flash this in, clear DTC's and reset LTFT's before logging. If it runs better, get around 25min of a log. No WOT pulls on this one; just easy driving with smooth pedal movements. Maybe take a look at...
Hmm.. let me look at this for a min. Something is off here; you still have P0103 showing up as "current" too. Did you happen to reset LTFT's?
Sounds good. MAF looks pretty good in that log. I viewed a comparison of your tune and the one I posted and the maf changes are minimal so that's looking pretty close. VVE; we will see what this next...
Post your tune as well so some of the more experienced guys can have a look. Looks like alot of weird happenings going on. bouncing in and out of closed loop - knock- trims showing rich, but o2...
Hey man! Just got back in town. Are these the most recent log and tune? If so, give this a go.

Im going to pm you my email. That 3rd log had something wrong with it.
Sounds good. I'll check back tomorrow. Just be mindful of not getting into PE, Knock, and aggressive throttle movements when trying to hit the mid-range rpms. A couple more logs like the last one...
Right. Try not to get into PE.
