My friend would be VERY VERY interested in being able to modify the TCU programming.

To bump this thread back up, did you guys end up discovering a way to Modify the Stock Legacy ECU (1989-1992) using Eproms? or the OBD1 port?

It's not going to happen unless your capable of tackling it yourself.
If you need programmable EM now, check out these recent threads:

I am working on a write up on how to use any of the plug and play EJ20G ECUs.
I beleive Doug also has a Perfect Power thread out there also.
