Just to be sure I'm giving enough info, I have a 2011 Jeep Wrangler that I swapped a 2016 L83/8L90 transmission into. I have been driving it for a while now and eventually I throw a code for running rich bank one and bank 2. (P0172, P0175)
Today I finally got around to installing my AEM wide band sensor. It's a 03-0334.
I haven't tried too hard yet to get it working in HP tuners but I did attempt it, without doing any searching first. I was unsuccessful on my first attempt. I will now search for getting that working so I can log with it.
I went for a test drive anyway, to see what the gauge tells me.
I currently have set it to AFR because I'm running regular gas but I plan to change it to Lambda because my engine does have a working flex fuel sensor and I do want the ability to run on E85 for fun. I'll learn to use Lambda so I don't have to do any conversion math...
Anyway, on my first start with the sensor installed it was running pretty rich like 16-17 AFR for a few seconds until it started to warm up. It did settle in to around 15 as it transitioned into closed loop.
On the test drive it hovers between 14 and 15 like I would expect it to. Mostly heavy on the 15+ a bit. When I pegged it, it fell to around 12ish. So far I believe that's probably good. But when I let off the gas and try coasting the gauge pegs out max rich every time, light throttle to coast, or hard throttle to coast it pegs out rich every time.
I have watched several goat rope garage videos and a HP Academy video but they both say to set the MAF using open loop. In my other thread I started about forcing open loop I got the idea I shouldn't be using open loop on a Gen V.
So my question is where do I start?
