Hello everyone
my dad and I were trying to tune his s10 with 94 blazer 4.3 v6 cpi 427ecm this weekend and the ecm scrapped out. We went to a couple pull a part yards and got 4 more. Now my question is which xdf do I read them in? I have tried all with 256 read only on apu1, that wasn't right so went to 512 read only and only got to read 1 chip in od and oe before I had to stop for a bit. 512 made the maps look readable but a little crazy but both looked very similar. So how would someone tell which is correct? BSWW, BPKX I'll post the other 3 in a bit but didn't see them in list.
Thanks. :-)
Just curious what the maps look like on them
