xt2005bonbon Posted July 10, 2018 Share Posted July 10, 2018 Was it cold idle or warm idle? Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 10, 2018 Share Posted July 10, 2018 I'm wanna say cold. I just cranked it after sitting for 4 months drained of fluids. Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 10, 2018 Share Posted July 10, 2018 Idle was normal around 1300-1500 rpms. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted July 10, 2018 Share Posted July 10, 2018 OK. IIRC, at cold idle (especially right after turning the engine on and/or resetting the ecu) it may do some timing advance. After that though, you should see 0 deg of VVT L/R at warm idle. And when you drive, the angles should also stay around 0 deg when NOT under load. As soon as you add some load, you should see the numbers climbing a bit and both in sync (+/- 1-2 deg). If you see one lagging behind, or stuck as some odd values, then you know 'she' is bad (or there is oil blockage in the passage---e.g. dirty banjo bolt filter).

TheUnsungWar Posted July 10, 2018 Share Posted July 10, 2018 Good to know. I only ran the car for 5 minutes to check leaks and get the readings. I didn't push the gas pedal down either. Just left it to run on idle. Again just worried about that negative boost pressure. I'll upload the screenshot in a bit Link to comment Share on other sites More sharing options...
xt2005bonbon Posted July 10, 2018 Share Posted July 10, 2018 So you had closer to zero boost pressure at cold idle? Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 10, 2018 Share Posted July 10, 2018 I had negative 3-5. Started at -3 went to -5. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted July 10, 2018 Share Posted July 10, 2018 Strange. I never paid attention to these values at cold idle right after start up. I'll check this evening.. Link to comment Share on other sites More sharing options...
Infosecdad Posted July 10, 2018 Share Posted July 10, 2018 That's normal for me, it's in vacuum at idle and whenever you are out of boost. I'm usually around -8 at warm idle. Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 10, 2018 Share Posted July 10, 2018 Good to know Infosecdad. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted July 11, 2018 Share Posted July 11, 2018 Good to know Infosecdad. mmh. Is this screenshot after strict cold idling? Edit: I guess not since I can see your throttle plate peaked at 57%... Asking cause I see a peak boost of 4.6 psi. Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 11, 2018 Share Posted July 11, 2018 I wanna say cold. I just cranked it to check for leaks and the vvt's info after sitting for 4 months drained of fluids. Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 14, 2018 Share Posted July 14, 2018 So which one would be the bad one ovc? The one with the higher angle or lower angle? If I switch them and the numbers stay the same for the position L/R) would that indicate a clog somewhere else? Link to comment Share on other sites More sharing options...
xt2005bonbon Posted July 14, 2018 Share Posted July 14, 2018 That's hard to tell just like that. You should provide a log. Are you stock? I am stage 2. And my VVT angles are set to peak around 11 degrees with a warm engine. When cold, it may peak a little higher. But then again, these numbers depend on the tune. Provide a log with gentle acceleration. Do not go full boost and stuff like that since she is 'sick' at the moment.. Link to comment Share on other sites More sharing options...
TheUnsungWar Posted July 14, 2018 Share Posted July 14, 2018 Completely stock except for the 2 gaskets touching the turbo. Replaced them with grimspeed set. I noticed that the app can capture the log but how would I share it here? Link to comment Share on other sites More sharing options...
