Bambu does not call TPU for AMS a replacement for TPU 85A. Its TPU table marks 85A incompatible with the A1 series and TPU 90A, TPU 95A HF and TPU for AMS compatible; the softness differs, so this is an option, not a like-for-like swap.
Bambu says TPU 85A/90A cannot go through the AMS lite and that TPU for AMS is made for AMS and AMS lite feeding. Our reading, not a maker-stated swap.
