Help identify this sr ecu for me?

[rustrocket]

I got this ecu with a bunch of motors, and i think it's from an S15 n/a...just cant figure out what designation.

Nissan PK
23710 1a101
a18-p19 gg0 9x29 .

Anybody have an idea?

Also, If you could help me identify what numbers should be on an autech ecu?

Thanks for the help.
