closed loop/open loop issues

[Cdc1221]

K guys i have a question. First off, i am simulating nb o2 with an lc1, no link. Nb wire spliced into the front o2 wire on the ecu. I warm the car up before taking off, and everything operates correctly for the first 4-5 miles. Then for some reason it is sluggisg getting out of closed loop. It will see 17:1 afrs sometimes and suddenly hits open loop and afrs drop to 12 or so wot. Then it will cycle back to CL when you let back off. This continues for about 10 miles. Then after that it wont enter CL at all. Afrs hang around 12 cruising. Its driving me nuts. Ive verified my tps works correctly through torque pro. Any help is appreciated.

I just want to get this resolved before i put this evo 8 ecu in. Its a hassle by itself without throwing in things not working correctly

Same tps. Idk, tps values stay the same at idle. I considered swapping back to the stock o2 but im not really wanting to weld in a bung until i put my new exhaust in. Just funny, i know my wb is working right, its calibrated, and wired in correctly. Just crazy how it doesnt switch
