Does anyone know the mines official website???
Took a bit of doing, but there you go. Translation into english is hilarious, the first lines on the page read:
In the midst of victory commemoration sale opening!
The tuning diagnosis opening schedule by the Katsura Noboru one player!
Ha ha ha…silly engrish! :E
Hey I have no clue how to read that… i was hoping you would be able to help me. I need to know what my mines computer is set to run. most importantly which injectors but if it could tell everything that would be awsome. The number on the mines plaque is 4946
thanx
Sorry man, no luck! Looked for 20 mins and came up totally empty handed.
That website is set up so poorly, there wasn’t even an email addy I could find for you to get in touch with them! I think what you should do is go to as many Silvia websites as you know of, and see if you can get either an online manual or at least an email to contact Mine’s.
Wow…normally I don’t just get totally shut down like that. This sux! 
Do they even give out that information on the internet? i think you would have to email them to find that out. And likely, that ECU was tuned quite some time ago.
looks like i have a bit of research ahead of me thanx for all ur help
