lenzhotrod, that link did help me understand a little better, now if my cam crank sync is toggling between yes and no, what is the issue? both sensors are new a long with the wiring hareness. Truck starts, runs, but has unbeleivable turbo flutter..... all the time, under load, no load a cceleration, decelleration and so on. I will check the ficm sync tomorrow, ficm is new too btw.
Hmmm I have always called it flutter, maybe I am. It does it when you leftoff durring hard acceleration, mine also does the same think under acceleration amd very little,
Feel free to school me...... I have tried most everything
id say your vanes on turbo are stuck... a for the yes/no, it should say yes all the time.... Remove BOTH the CMPs and CKPs and clean the moutning surfaces religiously... the sensors, even being a hair out will cause this
a break in sync... I just battled a truck that would start and die immediately. the block was rusted and pushed th sensor out. Another shop put two more sensors in but didnt bother to clean the rust off, so the sensor was sticking out, away from ring more than allowed, therefore breaking sync. Knocked the rust away, sensors in fully now, problem solved...
I have had brand new turbos be stuck. Either from bad VGT solenoid or sitting on the shelf too long ans vanes being stuck... I haver never used AE, I do all my work via IDS... If you had access to IDS, I could tell you how to dio the turbo... Check out your Ex back pressure sensor and tube. Whats your back pressure when going downroad full load? What does your max MGP read?
I have loggedthose readingswith my sct, but tomorrow I will monitor it with the ae, I can command the turbo to open and close. My ebp can read as high as 350kph. I will check it out tomorrow and get back to you. Epb sensor and tube are new Map sensor is new to they all check out at koeo
I appreciate the feed back
