Okay so I've been round and round with my car the past week or two. Some may remember I posted up about having detonation and boost problems. Well now if I have my boost controller set on (which is set to hold 10-11psi) I can hold the boost pretty well but the car hesitates/stumbles at WOT. Boosting non-wot causes the car to engine to cut pretty much completely. I spent last night soldering EVERY connection from my boost controller to the ecu and every other connection I could imagine. I had the cel scanned and had one code , p1127 fuel control (too rich). I turned my fpr back down and the boost back to 10psi (I raise fuel pressure to run 11psi which is when the code started). The cel is back on, hopefully just for the 2nd o2 sensor which is flapping in the breeze. Now, when I turn the boost controller off.... I should run set internal wastegate pressure which is 5psi. I run 5psi for a moment, the creep up to 8-10psi and it holds it????? Why? It is definitely creep as spike would hit x psi then drop back down, this holds it. Creep is usually caused by too much exhaust passing through the wastegate I believe.... I've heard of running to rich causing this. Also when the controller is off I can boost all day and not stumble/hesitate or nothing. WTF? Im am very unsure of what is going on at this point. I was thinking maybe I have a leak somewhere but I hold boost fine. Im going to pressure test the system anyway with the tester I designed. The apexi unit is accurate on every reading (rpm, speed, boost actuator voltage, TPS voltage etc). Nothing is out of spec so everything is working properly. I disconnected the solenoid that controls boost and turned off the unit. Sure enough I can blow right through the solenoid so its factory control. Turning it on makes it harder to blow through meaning the actuator is working properly. What the hell is going on here....
