Baseline dyno numbers for a 6.2L?

Did the ecu exchange beforehand. The first step was getting the truck running normally on the unlocked ecu. That took some work. The tuner i picked to do the job had already done a 2019, so that was one of the big reasons i wanted him to do the work. Had one small issue where one tool didnt work on the 20 which did on the 19. But he got it all sorted out pretty quickly. Be did a fantastic job on the whole project.

If you're at all a nerd, I've done some digging into these and it appears that it's a ~30 dollar processor that needs to be swapped (unlocked vs locked version). I "think" most of the cost is in the labor (This is an educated guess).

I do know the manufacturer is NXP: https://www.nxp.com/products/processors-and-microcontrollers/power-architecture/mpc5xxx-microcontrollers/ultra-reliable-mpc56xx-mcus/ultra-reliable-mpc5676r-mcu-for-automotive-industrial-engine-management:MPC5676R

It seems these ECUs are glued together in such a way that they're nearly impossible to physically open without permanent damage

fascinating, I was wondering if it was something like that or if it was as simple as solder jumper or something that enables writing. Definitely an electronics nerd I build my own circuit boards and have put a few custom programmed MCUs into my cars in order to get them to work exactly the way I wanted. I've used quite a few parts from NXP over the years.

wow, it's a 416 or 516 BGA package chip too. no kidding the cost is in the labor! I've hand soldered TQFP-100s before, 0.5mm pitch, 0.27mm pin width. I wouldn't even touch a BGA. between opening a fully sealed assembly that's not meant to be opened, dealing with a no-doubt conformal coated board, and desoldering and resoldering a large BGA MCU, then testing it to make sure it actually still works. Now I understand the price they charge for the unlock service.
