Edge Insight and Evolution EGT PID's (Error for 07.5-09)

[pcarlson]

Installing my Edge Evolution CS I noticed a diagram in the user’s guide that depicts the layout of the stock EGT sensors and different catalysts. This diagram that is listed in the users guide is incorrect for the BlueTec exhaust used on the 07.5-09 Dodge Ram pickups. Attached you will find the exhaust catalyst layout according to TechAuthority. Also, since the diagram is incorrect the EGT sensor PID’s are also reversed for post-DOC and Post-NOx EGT probe readings (I tested this and they are reversed). So if you are looking for the downpipe EGT reading (post-DOC) you will need to read the post-NOx EGT on the Edge Insight or CS/CTS until they update their software.
