Does anyone knows if a unisia jecs ecu of the 2005 impreza ts model 1.6l (N/A, with cable throttle) can be reprogrammed with ecutek tools or if is it reprogrammable at all? Because my tuner told me its possible but everybody else says the opposite..... this is a pic of the ecu chip

Hi, I recently remapped my 2005 ts turbo and added a larger air intake, I noticed that pressure was the default 0.2 bar. The performance is noticeably better so i,m sure that the tuner didn't fool me. The reason of my post is that I tried to raise pressure to 0.6-0.7 bar but fuel cutter hits at 0.5 bar. I took it back and he explained how the MAP sensor works and ecu cuts fuel (mine is a Hitachi PS60-01 boost sensor). he plugged a pda to the OBD and messed with the values(dont know exactly what he did) and told me to test again. I did, with same results. Next thing he did was to connect a zener diode (4.7 v) -see attached pic--- to fool the sensor but failed again. I tried myself with 4.3 ,3.9 even with 3.6 and car couldnt accelerate so I stopped. Nothing can raise the limit of the cutter and it seems that something else intervenes. {There is a temp sensor after the air intake filter, connected to the boost sensor but dont know if has anything to do with it.} Does anybody knows what is going on, a solution maybe? PS. I just need to go only 0.1-0.2 bar over the fuel cut limit, not anything extreme.

Hi, I recently bought a 2005 impreza 1.6l with an ihi rhb5 turbo (about 150 hp) and I noticed that the real boost starts over 3800-4000 rpm (100+ octane gasoline). The thing is that I dont want (for now...) more power I just want a little bit more torque at lower rpm (lets say 1000 rpm less). I checked over the internet and I saw 2 or 3 propable solutions. 1) wider exhaust pipe for lower back pressure in order to help turbo spool up faster 2) stiffer spring in wastegate actuator 3) remap ecu What is the best to start with and because stock ecu isnt a good choice for remapping I would like a suggestion for an aftermarket one. Thank you in advance.
