Would like to just for the hell of it start off with my stock tune adjust on my Suburban. It's a 95 with 454 and 4l80e. The stock chip is BPRK but due to it being in the stock memcal I don't know how to go about reading it without jury rigging some pins. I found another thread where EagleMark said originally it was BMHM, then BPRK and then CAJR. I however cant seem to find any of the bin files here or on the rest of internet. Ideas on getting the stock bin, or does anyone have it?
'90 Suburban w/ pretty much stock 350 TBI, 7427 ECM Conversion, sadly sold several years ago
'95 K2500 Suburban w/ soon to be 400HP 454
Here is what I use to read the EPROM in memcals. https://www.amazon.com/Generic-Break...NsaWNrPXRydWU= Insert in memcal at the EPROM location and read in a reader of your choice. I have a Moates Burn 2 and one of the Willem units to program/erase the Winbond STMicro knockoff chips. You could also purchase an HDR1 from Moates but I am cheap :)
