just got my wideband installed and it reads fine above idle cruising, but at idle in closed loop im getting like 20:1 afr and after about 30 seconds or so it might richen up to 16:1. just wondered if you guys could take a quick glance. Not sure if the o2's are acting up, or the slow switching is just a side effect of my cam or what. thanks for helping!

I am very new at this so take it for what it is, if you are idling in park why are your fuel trim cells all over the place, I se 4, 8, 19, 20,and 22. You show cell 22 (WOT) at 1900 rpms and 6% TPS. What else have done to the engine lately? I looks like its moving in and out of open loop. Turn some status bits on for closed loop fuel and O2 sensors ready to see if they are switch on and out.

 

Thanks any help is appreciated, iv done lots to the car lately, it currently has a 231/237 cam in it and i just got done putting on a set of afr 205's and most recently a set of 30# svo injectors with an ifr update by me, other than that the car is still running on the old tune from when it was cam only. I just got my wideband installed and wanted to start tuning it, but i wanna make sure everything is working as should be (02's for example). On the tune provided i did turn status bits on for closed loop fuel and it looks like once it goes closed loop it stays there.

 

If your 02s are slow its time to replace them. Has nothing to do with the tune.
You also have to drive the car to get an accuate 02 reading 02s can become lazy with the car just sitting.
After comparing mine to yours it time to replace both 02s on yours they should be switching like crazy not flat lining.
