DFCO question on my 2004 cav
Thursday, December 15, 2011 10:53 AM
Ok guys when I tuned my 2002 cav everything went fine. Now I'm working on my 04 and I'm having a problem. When I set my DFCO to be disabled like I did in my 02 I set the enable mph to 255. Well the 04 acts as if DFCO is still enabled. I let off the gas and my wideband goes full lean just like DFCO still being on. Am I missing something here?

This happened to me, I think I just turned it back on, and it worked fine. Would have to ask my tuner though lol

Did you disable all the DFCO fields?

You have RPM, MAP, and MPH.

I do them all.

Nope I didn't lol guess I'll try that. I usually just do mph in my 02 that's all I had to do. Guess the 03+ is different

Got any suggestions for the map and rpm settings... mph can stay at 255.

Off of advise from Ryan RPM usually put to 6400 for enable and disable (HPT will change it to 6375 (I think)

Map I think I do like 8 on both.

How weird is this. Even tho my wideband goes full lean my ipw is 1.0-1.1! Wth could this be because I'm open downpipe causing it to show full lean? My ipw indicates dfco working bit wideband is not... I still have to try your suggestion John I haven't had time.

How far is your wideband from the open part of the downpipe?

That's not DFCO if your IPW > 1. It's not a position WB problem too... the mine does the same. Just use the filter that i told you on hptuners forum.
