well, i got my safc II in the mail, and all the instructions are in japanese <not too suprised> but now i am faced with trying to install this thing without a manual. i have checked out the following website

http://www.apexi-usa.com/documentation.asp

but it seems to only have directions for the original safc. can i use these same instructions for installing the safc II in my vehicle? btw, 93 legacy n/a. the whole reason i got the safc II was to be able to control the fuel with the high- comp. pistons and ported heads.

thanks for any help!

Use the diagram for Hot Wire, Not Karman.

Red - power
Green - rpm signal
Gray - Throttle signal (TPS)
Brown – Ground
Black – Ground
Purple – Knock
Yellow - A/F Output (this goes towards the ECU)
White - A/F Input (goes away from ECU)
Blue is not used on the WRX (Used for Nissan)
Pink Not used (Used on Karman vehicles)
Orange Not used (Used on Karman vehicles)

 

the knock sensor was the only one i was sure i needed but didnt have, and it is good to know that some wires are un-used.

do i tune this the same as the original safc? that way i could just use the information on the apex-i website?

also, i was kind of wondering what kind of base map i should use, i dont want to start off at zero enrichment over stock, because i have the higher comp pistons, and i need to make up for this, correct?

thanks for the help!
