neat, this thing has the newest E78 PCM.  sent an email to LT1 if he is set up yet to flash.  its newer than the 07-14 i have done before. 

hopefully the wires just just disregarded i dont need haha

Love seeing these trucks go through the transformation

should be a good one.  took a 20 ton bottle jack, 4' chunk of I beam and lots of chain and pulling to bring the frame back down enough so the steering geometry was out of the frame rail.   otherwise it looks in pretty good shape now. 

just dropped the cab off at metalico this morning.

Funny how it seems the vans all get frame wrecked and rarely need cabs where trucks all last long enough to rot out.

Difference of being owner-driver vs fleet maybe?

i think its funny how anything possible on the passenger side is always bent, smashed, broken, or fell off haha


did some interwebing last night- i think if i make a bench harness with a working OBD, John can delete (or Patch the OS to accept VATS deletion) and then i should be good to roll with some transmission wire digging to "wake up" the 6l90 like i had to do on the last 2014 one. 


worst case i can buy the latest HP tuners bluetooth module and get everything i need to do it my self for 350$


not a ton of info on 2015+ used for swaps but i found a few threads with some light of hope that its very possible.

I would kick in on HP Tuners purchase if I can use to help 571 tune

tuning for that P01 PCM is free now, i have that ability.  you have the oldest PCM for LS engines i believe.  this E78 is 3 versions newer. 


as for being knowledgeable to turn what knobs thats a different story

and for a sloppy cam build your first step should be put in a 2800-3400 stall converter first

back on this for a day or so with jeep work finished up this week!

maybe run to Johns to see if HP tuners will play nice with the bench harness i made and PCM.
