  1. 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.
  2. 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.
  3. 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 discuss pricing\terms of service. Anyway your account allows a private message to be sent if you are intersted in details.
  4. 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.
  5. There is a solution since 2013. AVCS setting and knock strategy are to be recalibrated. MY10\MY11 EJ204 equipped Legacy\Forester were not able to leave a dealer without evident hesitation problem.
  6. I have never seen EZ30 that may run more than 50 kkm on LPG here in Russia. Nevertheless it is claimed that LPG compatible EZ30 engines were manufactured and probably sold in the Europe.
  7. As to my experience I have never seen those ecu's modified/reflashed. Moreover I am not sure there is a need to reflash those cars. Verify O2sensor voltage while driving. This is the only thing you may check yourself without an obsolete SSM1 scanner.
  8. 22611-AK770 22611-AK771 22611-AK772 22611-AK773 22611-AM130 Are also applicable for reflash as a spare
  9. Do you use to disconnect battery and reset the ecu while MAF cleaning ? This may be the answer. Denso MAF used for turbo Subaru and for EJ253\EZ30\EZ36 NA engines is usually starting to lean the mixture out. And cleaning may solve a problem. EJ204 engine uses Hitachi MAF that is prone to enrich mixture when failing. And cleaning is not a solution. Hitachi MAF disconnected\reconnected usually revives itself for a long time. Nevertheless Hitachi MAF failure does not lead to middle RPM engine hesitation and just causing P0172 error CEL. Anyway logging will show the real reason of the engine hesitation.
  10. 15-21 degrees total ignition retard relative the optimal knock restricted value observed for EJ204 stock calibrations gives 50-70% torque lost. Compare logs for a healthy and hesitating engines.
  11. What model year are you talking about ? MY03/MY05 NA engine has a hesitation problem that may be cured by reflash. MY99/MY02 NA Left Hand Drive Forester ecu is prone to a permanent failure during reflash. MY00-MY02 NA Right Hand Drive Forester may be reflashed for a better performance.
  12. Shame on me but I am not still able to verify how the engine sounds, leaks and smells remotely... Having logs I am to point long distance customers to check things under question themselves. Russian customers have an opportunity to come to my location and do all the best.
  13. Ten years old Hitachi air flow sensor is often partially faulty. It adds about 100 mv output voltage from time to time. It is evident in the log when the problem arises. Engine drops down idle rpm when the accelerator released. The problem comes in and goes out by itself. Air flow sensor connections\disconnections very often postpones the problem for years.
  14. 2 Mirek: The car is healthy mechanically. The software is to be corrected to revive the car. Mr pysiak2247 did all his best. You may follow the same way as others did and reflash the original or spare ecu against hesitation. Subaru officials would like you to buy a new car. This is their primary business.
  15. Hitachi EJ204 air flow meter has a problem around the wiring connector. It often outputs more voltage and causes P0172 errors and the connector reconnected is usually solves a problem for a while. Denso EJ20\EJ25 air flow meter often outputs less voltage and causes P0171 errors. Cleaning may solve a problem and may kill the sensor. Thanks for the trick of using small ultrasound bath filled with IPA. I may try this solution for Denso controlled engines. The problem is that not all around are as lucky as you are.
