But since I'm not going into boost, it should halfass work. I'll try to grab some tonight
No idea if this will help or not, but I never had good results with the KPro and closed loop. It would always start drifting off in one direction or the other (usually lean) for no good reason. After a day or two it'd be undriveable. I brought the issue up several months ago and Hondata made some changes to the KPro software in response, which did improve things. It still didn't work that great for me though so I just disabled closed loop completely and its been very solid for several months. Even with the weather changing from 90's to 40's my AFRs have been great.
Maybe leave closed loop off, reload your tune and test it a bit.
