No more bloody safe mode!!
The Easter holiday has been good to me, finally got time off from worK, connected the diagnostic wires, (Read memory and test connectors)... Suprisingly contrary to my initial assumption that it was the Speed Sensor causing my problems. Anyhow the subaru self diagnostic system is pretty simple... basically every code it pulls is in reference to one of the many sensors on the car. So once you got the code you know what sensor is at fault.. Anyway after pulling the codes I got the following
31 ... Throttle Position Sensor
32... O2 Sensor
33.....Vehicle Speed Sensor
45... Pressure Switching solenoid for boost sensor/ over boost
The O2 code came from starting and running the car from first start up without O2 connected..
VSS same reason I hadn't gotten my new VSS from Subaru.. this made the vss simulator useless since the factory vss providing the signal the sti ecu needed in the first place... didn't know that. 0-5v switching 4 times per wheel rotation.
Now Code 31 and 45 is interesting.... I had to think bout it for a while over some food. The tps and Pressure sensor have one thing in common... I realised that its unlikely to have both codes at the same time. Both system operate on a 5v circuit,,, not 12v. So after doing some cheCks and refering to the wiring diagrams, the two are connected, they share a 5v power source. After a voltmeter reading confirmed the absense fo that I traced it to a wire I cut off earlier that I thought was not needed,
The car immediately came off of safe mode, idle dropped to well too low to idle since i had messed with the idle valve to get it to idle,,, had to raise it back that works perfectly now. No more back flames between shifts

, Throttle response drastically improved, drastically! The car revs solid to 8000rpm at full throttle at an astonishing 16psi 1-3 and spikes to 21 psi in 4th and 5th,ripped an awd burn out without race changing just simply pressing the gas my fresh set of tires. Don't like the spiking and stock bov moans under high boost bouncing off the speed limiter isn't nice either I was in a 35mph zone
Time for mods!!!!!
