As the subject says...
I have a spare ECU, with a ROM from Mine's , it was in my Version 4 STi transplant. The ECU will also work with a Version 3 (same ECU plug) to drive a EJ20K.
I've used it for the past 2 years and have recently swapped it for a fully programmable ECU.
Asking $250 + shipping from Toronto.
Cheers
