I need help! [Idle Air Controller]

I removed my idle air control valve in order to learn and see if I could trouble shoot this occasional high idle issue I have and I messed my bike up. When I put my iac back in it won’t run right. With the spacer that the older models have it runs about 800 rpm. But once it gets shut off and restarted it won’t stay running. With out it it runs at 2000 cold and 1300 rpm warm. I’ve tried everything I can think of regarding the relearn process. Ive read every thread I can find regarding this. I can’t get the ecu to set the idle correctly. I can turn the key on and then after the iac sets I can spin the valve plunger 4 turns farther down and it runs perfect at 930. Once I shut it off and restart it it runs way to high. I do have a PC5 so I mess around with it if needed. Is the tps programmable? Is there something I’m missing? It was fine before I messed with it and now it sucks! Oh and no engine light.
