1991 toyota Supra Turbo
Hello so we had a SAFC laying around and we decided to wire it up we searched for diagrams, pinouts and all that and everything works and lights up fine. it reads tps,rpm (reads rpm alittle off). Only thing it doesn't read is karmen. It stays at 3hz all the time while reving, idle, and when keys in ignition. we checked the wiring it was connected to the afm. We just dont know why the SAFC doesn't read the afm or change the fuel mapping. We set it up correctly in the SAFC. Just dont know.
