  2. Disconnect the secondary air valve in front of the driver. A rusted valve shorts a power line of the throttle and accelerator sensor. After that throttle control will be disabled by the engine ecu. If the wiring connector itself is already rusted you will need to cut the connector off. Have in mind there maybe a pass thru wiring of the ground power line inside the connector. Do not break the ground line power connection. If this is not the case verify carefully the engine loom wiring. The big connector under the throttle ( passenger side ) is a common problem after engine mounting.
  3. Faulty CAN bus may not prevent to connect ecu diagnostics and more over to start the MY06 Subaru Legacy. OBD scanner and Subaru SSM diagnostic tool communicate via k-line and CAN bus is not used for diagnostics purposes. Have a look on to the car OBD connector. There is no CAN bus line connected to pin6 and pin14. You are to find more experienced Subaru diagnostics personal...
  4. There is the only 8pin 93C66 chip that holds immo and VIN information near to 240pin processor chip. Monkey can do..
  5. The complete immo set includes the dash board as well. Just the ecu itself is needed if your original unit is broken ( that is still under question ) all other things you are waiting are useless.
  6. Completely failed Hitachi ecu is a rare thing. You may source 22611-AK770(771/772) ecu and resolder 8-pin immo chip from your original ecu into a donor. You may also use 22611-AM130 ecu but just Subaru diagnostics will be available while OBD diagnostics will fail. If a donor ecu installed communicates with a diagnostics equipment and reports P157x immo codes you need just a solder to revive the engine. In fact any 22611-AK67x, 22611-AK77x, 22611-AM030, 22611-AM130 may be reflashed for your car with immo disabled or copied from your original ecu.
  7. MY03\MY05 2.0 SOHC needs EGR to be disabled and knock strategy to be corrected. The same for MY02/MY07 2.5 SOHC with JECS\Hitachi ecu.
  8. I am surprised. What model year Legacy IV 2.0 SOHC do you see around ? There most recent 2.0 SOHC Legacy were burn in 2007 for JDM market. The most recent EDM Legacy 2.0 SOHC was 2005 year made.
  9. Are you talking about a rigth hand drive car ? All Legacy IV 2.0L I have seen here were DOHC.
  10. Subaru used reasonable ignition timing for enabled EGR operation up to about 2005. The drawback is that after EGR valve\pipes have been clogged the engine needs the next grade fuel RON92>RON95>RON98. Cleaned EGR valve\pipes\heads\pistons have restored the engine shape. Jammed EGR valve finally destroyed idling and part throttle operation. Later Subaru stopped ignition advancing under EGR operation. Most probably due to the need to cancel EGR system service. The low end part throttle torque was remarkably lost for high grade gasoline as a result. Full throttle operation was still fine.
  11. I use to disable EGR. If the valve is not completely closed at idle it should be blocked after that. What errors or readiness monitors not completed are reported by diagnostics ?
  12. That means that EGR is faulty OR the owner disabled EGR in improper way and did not set Readiness monitors as completed. If you do not mix EGR with a secondary air system that many owners do.
  13. 95% that your mechanic is wrong. There is no evident problem with oil valves at room temperature conditions. Solenoid coils are starting to block solenoid cores moving at 85-100C temperature degree. Log your car riding from 50C coolant to 90-95-100C coolant and compare VVT angles sync\following to your current tune.
  14. AVCS timing should be verified by logging at the hot engine. 95-98% cases are usually related to overheated oil vavles. Most often new oil valves solve the problem. Sometimes camshaft sprockets or oil channels are to be serviced. Faulty position sensors will cause CELs, usually not directly pointing to the sensors or may prevent engine starting.
  15. Engine mechanical noise is rising due to aging. The knock detection algorithm is calibrated for a factory new engine and has a drawback for noisy engine operation. Subaru staff knows this problem from about 2006. And makes EJ204\EJ20F engine ecu calibrations applicable just for 3-5 years old engines. There are no software updates after warranty period. You are welcome to buy a new car after that period. Within a warranty useless "engine combustion chamber cleaning" is recommended. It is black marketing from my personal point of view. All Ladies Do It. (C) No one EJ204 engine was sold in USA. Thus there is no ground for VW alike scandal..
  16. The most recent update postpones just come hesitation for about a year. And does nothing after warranty period...
  17. Alternatively a spare ecu may be sourced in Russia and a ready to go solution may be sent. Final tune according to the local fuel is done remotely if needed. There is also a lot of spares in Poland at hand of my customers.
  18. 2 morosek: You are to log the engine while running. And verify VVT angle left\VVT angle rigth values Vs engine RPM and engine load. It is almost impossible to have AVCS system working properly with 200 kkm on the clock and original oil valves. Neither EGR nor secondary air system you are going to clean are related to 2000-3000 rpm flat spot.
  19. First of all you are to tune the ecu against false knock detection that is the cause of 2000-3000rpm hesitation. Remove a rusty secondary air system and a clogged EGR. Nothing but a throttle body needs to be cleaned. Inspect and recover AVCS if needed if there is 100+ kkm on the clock.
  20. Subaru has no profit if you revive your 15 years old car. They need to sell new models badly. D5854EC7 update just postponed 2000-3000 rpm flat spot to the end of a warranty period coming in 2010-2012.
  21. D5854EC7 is the most recent. And is still useless. You are welcome to buy a new car.

  23. There is no deep 2-3 k rpm engine hesitation in the logs. The common flat spot problem is just coming and this is probably the cause why the previous owner sold the car. Anyway the solution exists and you may fix the problem when the driveability becomes inapplicable.
  24. Without an applicable software ELM compatible Vgate dongle is not very useful for in-depth Subaru diagnostics. Most probably JDMscan from Google Play is already applicable for your car. I can not say for sure. Almost any cheap China k-line cable is applicable. I provide an applicable cable together with the reworked ecu. Immo maybe copied from the original ecu in advance or later.
