Located and purchased an ECM from a 2007 XB12 (which is suppose to be compatible with 2004), installed it on my 2004 XB12S, reset the TPS, flashed the maps that I saved from my ECM before uninstalling, and went through the EEPROM settings to make sure they were the same.
Before I do anything else, I have a question. The EEPROM from my original ECM is BUEGB and the EEPROM in the replaced ECM is BUEIB.
What I was wondering is if the flashing of my maps and the TPS reset is all I need to do or are there other settings or changes I need to make to the ”new” EEPROM? Any differences between these two EEPROMs that I should be aware of and change?
Have been out of town the last two weeks to be with family in Indiana after my dad passed and am now scrambling to get caught up at work. We had an ice storm here in DFW last week that shut everything down. So, have not had been able to get back to this for awhile but hoping to get her out on the road soon to see if this fixed the tach issue.
