Is this ecu trying to be run stock? just cut the jumper at location J1 on the ecu and that will return the ecu back to stock form. I wouldn't try and run the chip that was in the ecu unless you know what was programmed onto it.

Yes, stock OBD1 ECUs can be external EEPROM from the factory. They do this for California's emissions.
It's all good. All of the work has already been done for you. Don't cut J1. Just desolder the EEPROM (28 pin), put a socket in, then put in your Uberdata chip. That is all you have to do.
Leave J1.. Desolder 28 pin EEPROM.. solder in socket.. Insert Uberdata chip.
