TSP Stage 2 Cam install L86 need help with start up tune. dies after engine warm up

[6.2Silverado17]

Hey guys, needing help with with start up tune after tsp stage 2 cam kit install, engine starts up then dies after warmup then will not start until cool again so im really needing another set of eyes on the tune to give some direction on what ive obviously missed. Posting tune file, stock file and last 2 logs

It almost looks as if you pulled a front O2 for the wideband and then killed the codes so it would ignore it and now you have no fuel control........ Your bank 2 O2 shows super rich whilst the wideband shows beyond super lean. Need to check that wideband on top of everything at the moment.

FYI on these since you've already ticked it off. Put the precat O2 back in with the post cat O2's still in and let it run long enough to do the cat and O2 test - takes about 5 minutes of idle time. You should have trims working at this point as long as where you killed the long terms it will still have enough fuel trim shift to allow the test to run. Then pull the rear O2 and put your wideband there hopefully after figuring out why it's showing so lean. These use post O2's for rationality checks and even though it'll look like it's doing something with fuel trims, it may not be controlling it right until it passes the rationality check. The newer E90's are even more sensitive with this.

Thanks Greg your help and time is very much appreciated and valued greatly. Ok so I got the wideband issue corrected and also found #43 Engine fuse blowing causing engine to die and hard to start and if it did start it wasn't going anywhere. So i noticed when it would happen i would lose comm with the MAF, it would 0.00 out and engine would die then spin no start... finally found the source of that problem There is a plug that does not connect to anything and just sits on the corner support of the frame at the Front of the Fuel Tank. This Plug is capped, BUT, not tied down to anything, it was dangling off the corner support shorting against the frame. So i solved that issue however, I'm still having problems with the engine it running until warm and then dying im posting the most recent log of this happening if you could take a look please and let me know what your thoughts are and what may attention in the tune.17 Silverado L86 tsp Stg 2 cam log 4.hpl2017 Silverado L86 tsp cam install Startup log 5.hpl most recent log i changed VT tables back to stock

B1S1 still showing to have a problem and I would recommend roughing in your fueling if nothing else. Are you sure all of the grounds are tight and connected?

It'll either be better or worse.

What you're experiencing is the usual idle blip. Just before the rpm dips timing starts jumping up and down then she tanks. This is all cause of evap, cat and O2 test taking place. You have to set the tune up to work through these. You had you hpfp settings off for the cam lobe. I may have not adjusted it high enough, but you can see the axis I changed and you'll need to increase it the percentage lobe increase. I also made changes to pressure to better balance it out for the higher loads at idle along with several other things.

thank you for the file update, so I increased the y axis of leading edge to +32% in comparison from the stock file for the fuel lobe diff and the cranking and start up is a lot smoother except it dies not long after scan attached. So I then added 5 deg of timing to high octane spark table around the idle areas just to see how she would react,.. at first she was receptive i had to give her a little throttle for an incentive to keep running at first but she then decided she didnt want anything of the sort got ticked off and shut off again. Most recent logs/tunes attached. I know Ive got to be missing something and/or hung up making adjustments in the wrong areas.

Put the external load back close to stock and then are you sure you don't have a misfire on bank 1? You also have several cam codes and other codes set from the looks of it. The idle settings can cause one to just stall.

I went ahead and did the adjustments to this one. Injection timing especially for cat lightoff can cause stalls if this and the dtc corrections don't make a difference.
