Ok, I'm resurrecting this from the dead sorry. I have the 4W ECU & am currently looking into my options for a stand alone. Was it found here that the 4W is compatible with the EJ20K ECU?
I am looking into something like this.

as well as the ViPec version for 97/98. Wanting to know if they will work with my '97 4W ECU
