2005 Silverado P59 OS: 12606961. I finished everything up for the flex fuel as far as sensor and wiring. I found an 05 Avalanche L59 Flex Fuel with the matching OS in the repository. I did the seg swap for the Engine and Engine Diag and made sure everything is enabled in the tune. Performed a write entire just like I did when I successfully did an 80e swap. I cannot get it to recognize any of the required parameters for ethanol in the scanner. I double checked wiring and ground. Anything come to mind? Thanks.
