Probably true, the other day when I put on the new tune it seemed a little smokey smokey but it could have been a ton of vapor built up.

 

Do think maybe It needs another set of floor mats????

 

Well since I robbed the floor mats out of this truck to put in the Sierra, yes, yes it does! Might do some nice carpet ones though since this isn't the work truck anymore lol

 

The rich idle in open loop can be adjusted by changing the tables in the Open Loop EQ Ratio table. In your mild winter climate I'd make all the tables 1.00 from 86* degrees to 284* in the table. The log shows the idle leaning out as it should around 135* 140* degrees. This table is like the choke on a carbureted engine so it's normal to be rich on cold startup.

 

Thanks Red you make it relatively easy for me to understand these tables lol
Went ahead and did this, I sort of scaled down the rest of it back to match the new 1 86* and on. I think it should be fine.

Here is a picture of my idle as well. I used to idle at 650 so I think I may drop it down to that level or maybe try 600. I will try it after I load up this new tune though. Don't want to do too much too soon.

 

In the idle table I usually add 50 RPM over the base idle with the AC on (in gear)

If I set the "In Gear AC off" to 650 RPM I'll set the "In Gear AC on" to 700 RPM.

P/N AC on and P/N AC off (in this scenario) I'd match the "In Gear AC off" at 650 RPM.

Of course YMMV

 

Gotcha good point

 

PE on this truck is awful. 70% throttle drops my AFR down to 8.
I need to get a new log though as I have done some tune changes and realized my last log was on the wrong tune.

 

Okay so here is the current tune and a log. Works good except at 70% throttle the PE kicks in so hard that it drops AFR to 8. Very not good.

I did do some editing of the tune to the turkey dinner tune that I have linked as well and it made the truck drive awful and everywhere the AFR went rich. Super smoky as well. Didn't even touch the fueling but it sucked so I will be scrapping that one and working back on the 5.5

Edit: Also look at the fuel trims. WTF is going on there? Truck does not seem to be running lean at all lol

 

I wouldn't worry about the PE until the fueling issues are straightened out. Short terms are peaking in the 30% range. You need to get them closer to 3% then the o2's can trim the short terms in. Start over and do the MAF first then the VE. Once that's done the PE might fall right in line or need just a little tweak.
