PLEASE HELP- ECU throws bad MAFS code after SAFC Install, won't start - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok I put a SAFC on my S13 SR today and I know it is installed correctly. I set the settings to 2in 6out for Z32 MAFS, 1/1, 4 cyl, up arrow. Try to start the car and it cranks and cranks, wont start. There is no fuel on the plugs and I checked injector voltage and it looks like they aren't opening. ECU codes MAFS and coolant temp sensor (has been bad for a while). Ive been running a Z32 MAFS with a secret services tuned ecu for years with no problems but after SAFC it shows bad MAFS code?! This sucks please help with any suggestions

double check the mafs input and output wire connections, they might be loose.

recheck the solder joints on the safc I had the same issue when I first hooked up mine.

try setting it to 6in 6out since your ecu was already tuned to read the z32 maf as a sr one
