Batee is your best bet. I understand that the 1990 ZR-1 programmer is unique and has TWO part numbers due to an issue with some original programmers would not reset correctly after battery disconnect. I know there is a TSB on that somewhere. So if you get a new module get the updated part for 1990 (which are extremely hard to find).
