Hello, I want to apologize in advance for the stupid questions. I'm trying to get into modifying the GM truck BCMs, assuming that the configuration is on the 93a66 eeprom, I managed to read out the eeproms of 4 different BCMs I found the VINs, the characters are reversed in pairs with the last digit...

I have pulled the bins of 4 07-13 gm truck BCMs today, If anyone wants to have a look at them, there you go!!

got anywhere with that?

I have a few BCM's here, I can open one up and take a few pictures of the components if anyone is interested

as the title says, a wiring chart to convert the 97 ish vortec to the easier to tune 98 pcm and to the even better 411 pcm

Hello,

Has anyone looked at getting into the GM BCM's to adjust or activate options?
