PS, did you try out my transmission shift points?
I did, but it's been a while since then and I fussed with the tune since then and think I rolled everything back. I just need to give a good go at dialing in the tune on this thing and take a Saturday to work on it. Those have been scarce lately but that should be getting better now that summer is over. I'll give it a re-look at that point.
So little update from weekend camping trip, last trip of the summer. Tow/haul was a nice add and made it much less fussy to drive. There's still some adjustments I'd like to make on that as well but it was an improvement. I do notice sometimes the trans will go full line pressure and have HARD shifts, so I'm hoping something deeper isn't going on there and it's just a tune thing.
Also noticed now my tune is running PIG rich, like .88-.9 lamba ALL THE TIME, and my towing milage dropped hard since earlier this summer. I don't know what I did there or what happened, but it's almost like it's staying in PE constantly, even when cruising with the trailer. It also feels like it doesn't have the power that it should while towing. I really just need to hammer out on getting the tune "good", especially with VE and MAF, then reviewing where things are and going from there. It's a time thing...
Took a day trip to a nearby brewery Saturday, about a 10 minute drive, and got the flashing SES indicating a random misfire. I didn't feel anything, truck didn't buck or make any noises, and if it wasn't for the light, I wouldn't have noticed any misfires. So that hasn't really gone away I guess, and when I look at HP Tuners I still see those random misfires on 4 and 7. Not sure where to go next on that, maybe making sure I have good separation on all my plug wires ¯\_(ツ)_/¯. It didn't do it at all while towing.
But! The A/C worked the whole time thought, so I got that going for me, which is nice.
