  1. 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.
  2. 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.
  3. 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
  4. The most recent update postpones just come hesitation for about a year. And does nothing after warranty period...
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. D5854EC7 is the most recent. And is still useless. You are welcome to buy a new car.

    EJ204\EJ20F engine CR is above 10.5. There is no much room for boost pressure. I have never heard a positive result for compressor installations for EJ204 and EJ253 Subaru NA engines. MAF is always fooled by a compressor air flow\swirl. There were positive result for a compressor installed on to MY99-MY05 EJ15\EJ16\EJ201\EJ202 engines that do not use an airflow sensor and has moderate CR from the factory. All of them were (long going) projects not everyday family cars. The most used options here in Russia are as follows: -EJ20X\EJ20Y engine swa
  11. 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.
  12. 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.
  13. A spare ecu may be sourced here in Russia. If you have a keyless start system a copy of immo sync will be needed. Otherwise a spare may be sent with immo disabled. An applicable cable for logging and ecu recalibration is provided. The original immo may be copied by means of that cable or any k-line adapter. Calibrations for petrol, LPG, E85 are provided at no additional cost. If any k-line cable is available it will be useful to have some logs for diagnostics. I am not sure that according to forum rules this is an applicable place to disc
  14. This is not a factory software update. A lot of forum members and other Subaru owners had sent the ecu to my location for ecu reflash. You may routinely ask them if they are satisfied by results.
