When I asked last summer, during a pressure sensor replacement, about a software update, the tech said in his experience, updates normally were required because the EPA kept requiring leaner conditions, which lead to other issues. His advice was unless I was having a problem, leave the updates alone. Of course, my C9 is in a 2005 coach.

My C9 runs at 204-206 on both the analog dash gauge and on the Scangauge. By the way, trans temp also 202-206...

We bought a Scangauge D for ours last year and it does exactly what it says it will. We are happy with it. Our coach readout is an old style so the extra info is worth it. Make sure to read the manual and send in the extra codes to get extra parameters sent to you by Scangauge. By the way, there is a lot of them, and a lot of writing. It takes about a half hour. By the way, you can download the manuals first if you want to read them before ordering the Scangauge. Check for coupons on Advance Auto. We paid less than $130 by using them. 2005 Fleetwood Revolution LE 38X. Cat C9

Yes, yes! We have owned our coach (2005 Revolution LE) since October and until it got hot outside, never knew there were fans not coming on. I added an extra fan from below and that fixed the "warming up' problem but on further servicing found just what bambiajkora had found. My black and white wires for the fans were reversed! Changed them and heard the fans come on and the Norcold and I are now happy!
