So it finally came back. There is something to note, im hoping someone will know what it means. Normally after a memory clear/ecu reset, when everything checks out the check engine light will flash on and off consistently until i disconnect the green connectors. This last few days when i was running...

took it for a rip this morning, still running good, no codes no limp mode. guess we will see how long it lasts

So i decided to check the TPS calibration, it was slightly off 4.89v throttle closed so i adjusted it to 4.7v (manual states 4.8 is the upper limit) Then some weird stuff started happening, the idle kept sticking on 2k rpms while driving around so i checked for codes, nothing showed up, so i did the...

So with the mbc hooked up on 10psi its okay but if i do an ecu reset its WAY faster on the same boost. Limp mode 10psi 10.0-10.5AFR wide open throttle. Normal mode 10psi 11.75-12.0 AFR wide open throttle. Whatever the ECU is doing in limp mode is more than just dropping the boost via the EBC, its pu...

AEM wideband installed, manual boost controller installed, for the most part seems to be okay under full throttle air fuel ratio wise, everything feels okay as well. I do need to relearn the idle as it hasn't been that great with multiple ECU resets. idles low and irregular with very lean readings. ...

replaced the pressure exchange solenoid, didnt change anything.

I ended up buying an AEM wideband kit, gonna install that tonight and take a look at the fuel air ratios and make sure its running safe

Well i think i have a spare map sensor and pressure exchange solenoid, i will also do some electrical testing today and see what i can figure out. something else to be considered is i might have electrical interference/bad knock sensor wiring, i may end up running a new shielded wire to see if anyth...

Okay so running 93 octane fuel didn't change anything I did try something a little different for diagnosis purposes, first i tried moving the knock sensor to a new location on the engine (to desensitize any knock readings going to the ECU). Reset ecu, limp mode came back within 5 minutes of driving....

Well, the injectors were down 10 percent on flow. Got them cleaned so now they are good to go, new screens installed as well as O rings. Got everything back in, reset the ECU, car was running fantastic on 10lbs of boost, everything feels great, unfortunately the ECU kicked me back down to 5psi in ab...

Pulled the fuel filter this morning and cut it open to see what was inside, it was super dirty. Decided to pull the injectors to check the screens and they were real nasty as well. Dropped them off to get cleaned/flow matched with new screens. Will report back at the end of the week when I get them ...

I already tried cleaning my original MAF, with MAF cleaner, reset ecu, limp mode came back within 5 minutes of driving. No codes

I replaced the MAF, reset ecu, limp mode came back within 5 minutes of driving. No codes


I will recheck all of my vacuum lines again.

Replaced the O2 sensor and verified mechanical timing, cleared ECU, switched back to limp mode in several minutes of driving. No codes Something i tried later in the day was resetting the ecu and driving the car super easy for about 15-20 minutes, no boost, no more than a 1/4 throttle or so. I tried...

Replaced the Ignition Control Module, cleared the ECU, it switched back to limp mode in several minutes worth of driving. No codes.

Replaced the knock sensor, cleared the ECU. issues comes back after 5 minutes of driving. Still no codes.

I will try and keep this as simple as possible Ive got a 90 subaru Loyale that has an EJ22t swap. Cone filter, silicone intake tubes, wrx factory intercooler with the recirc valve, stock turbo, cat delete and exhaust. everything else is stock subaru, just as it was intended to be in a Legacy SS Engi...
