I just got given a field sfc hyper r fuel controller (similar to Apexi safc) I've searched and searched and googled for installation instructions but all links are dead. RETed had one and I found which way to set dip switches according to him. More info via him is impossible as he hasn't been active for 4 years. So if anyone is running one and can tell me what wires go where and confirm the dip switches I would be most appreciative.

S4 turbo (s4 jspec electronics s5 Jspec motor)

Thanks I'll definitely give it a go. Found this, gives wire allocations. Same site.forums.nasioc.com/forums/showthread.php?t=100493 still won't know how to use it haha and would like to confirm the dip switch configuration. I'll try messaging him

If you need to find reted, he does still frequent rotary car forums. He doesn't frequent this one anymore though. The owner of this site wont allow a direct link to that club though.

had no luck contacting RETed but found this finally Field’s sfc – manual for the operation manual. found this on a subaru site "these wires you need to tap into the ecu. no cutting needed
red-power
black-ground
green-rpm
white-02
lightblue-speedsensor

these wires are the map sinsor wires. you will need to cut the ecu mapsensor wire.
orange-cut map wire going to the ecu side
brown-cut map wire going to the engine's side

purple,darkblue,and yellow are not used. tape these wires out of the way." though i tapped the speed wire to the cruise control box under the dash and speed doesnt work so will try the power steer control unit wire (G/R wire) it never reaches the actual ecu so doesnt need splitting between the light and dark blue wires i assume.

the pinouts are as follows for a s4 turbo https://www.rx7club.com/attachments/...ness-oneex-jpg with the O2 signal being the pin directly under the ground pin.

the dip switches on the back all up except 2 and 4 on the 8 switch bank and according to a long ago post by RETed all up on the 4 swicth bank.

so yes it took a month or whatever to find the info but ive installed it and fixed my idle mixture (yay!smooth idle) will invest in a wideband and or dyno time and tune the rest. so the info is here for the next poor schmuck who is given one. got it free, it fixed my issue and is quite a funky little unit. has 0-400m time and speed recording. peak speed and rpm recall. 1000rpm increment +/- 30% fuel adjustment or on the fly in 100rpm adjustments. also digital speed or rev counter and a narrow band o2 sensor. all lit in red, green and factory matching amber.
