I recently replaced the ECU on my 1996 993 with a 1998 ECU to correct some on going check engine alarms. Now I have two alarms that are related to sensors for the 1998 model year that are not on the 1996, such as fuel tank pressure. I also have an "Improbable Hall Sensor" fault that has followed the ECU change. Other wise the car runs great.Is there a 1998 ECU I/O pin out diagram abailable? Any comments on the Hall Sensor fault?
