Where did you get FAST from? I dont see it anywhere in that picture?
The ecu that came with my redtop sr20det has a F.A.S.T sticker on it and I havent found out what it's for either. All I could find was that it could be fuel, air, spark, timing -- possibly japanese tuning company?
My ecu has a sticker on the front and then stickers around the edges that would have to be broken if the ecu was opened up
