Hi,

My '92 FD is from german origin and the sticker on the ecu says N3B7, so it's 8-bit..

If I look on ebay for an ecu for it, al the ecu's are N3A7..

Do japan/us ecu's differ with europe ones? Probaly for emissions and stuff..

Is is possible to use a N3A7 in my car, without to much problems?

Greetz!

Rub.

i know the jdm ecu plugs into the usa harness and works, so the eu ecu should too. as far as details go though, i have no idea
