Have a 1994 Olds Bravada with the 16197427 ECU, swapped a Rebuilt 350 .040" over with a hotter cam in it. Running TBI right now since the harness was basically a direct swap over.
I bought a BJYL chip just to get it started, I chose that one as it matched my gear ratios in the differentials. I did see a couple things to watch out for like disabling the PWM controlled TCC and adjusting the knock sensor voltage since apparently the V8 used only one knock sensor and my 94' doesnt have the PWM TCC.

I'm here to get help finding some tutorials relating to actually programming the chip itself. Mostly in relation to Buffer Addressing and Chip addressing.
I bought an XGecu T48 programmer for this project. The first thing I would like to do is to read the tune right from the MEMCAL but it fails checking the chip ID, comes back as 8F 85. Its not a huge deal if I don't get it, I downloaded the BJYL bins from here.
I have a "new" type of chip from BoostedNW, that 2Timer one that he sells over there, as well as the other supporting adapters to work with the MEMCAL.
My main problem I am having is that when I follow the intructions from BoostedNW, it seems to get the program on the chip, but its shifted by one byte. So the program starts at 00003FFF not 00004000 like the BJYL BIN file. I dont know much about Buffer and Chip adressing and I guess thats why I am here.
I was following the instructions he has here: https://support.boostednw.com/kb/faq.php?id=1



One thing I didn't understand as well, when I would load the BIN into the buffer using his instructions, the program would start at 00008000. Wouldn't that not include the whole program since in the BIN itself it starts at 00004000 and goes all the way to 0000FFFF? I tried to play around with it but his instructions were the only ones that even got me close.
