Flex Fuel Conversion Help
Followed this thread and got a PCM from a 2004 Express Van.

Ive checked the wiring multiple times and I am 100% sure it is correct. It wasnt correct at first and Im wondering if I fried the sensor.
Please give me some feed back on the attached tune before I buy another sensor.
