Does anyone know the part number for the JDM 3sgte ecu from a 90 or 91?

The reason I'm asking is I am getting codes 21, 25 and 71. 71 is EGR code and as far as I know the JDM 3s does not have an EGR system. If anyone knows the ecu part number it would help out a bunch. I have a new o2 sensor as well and re-wired the o2 sensor right to the ecu, if I have a usdm ecu it would explain why my o2 code is still there, I know I'm not running lean either cuz I get like 12 mpg.
