    Normally 30FE codes only after prolonged use are sticking wastegate actuators/rods.

    Thanks for the info, much appreciated. Some interesting custom stuff coded in your tune there. Do you have plans to sell your tune in continental Europe too? Saw you have some resellers in the UK, but none in Germany, France...

    I can not figure out why you have this error and others don't. Would you please create another account to test and see if it still happens?

    Wait. What?
    Is there a limitation build in the DME for cornering torque?
    What if you add a Quaife afterwards?
    Can this parameter be set / changed with a tune? Probably only with a flashtune I presume...
    There are two theories to arguing with women. Neither one works

    I was wondering more in a generic way how does the piggybacks handle reported torque? Is it "lowered" to something the DME will be happy with or? @Terry@BMS you have any input here?

    is just the stock torque. DME thinks running stock values.

    Terry,

    What would be the course of action to remedy this? Lubricate the actuators?

    Vas , i remember Mr.5 having this issue at the track quite often. I think he also did a thread about it and yes lubricate it should fix this but it will come back i guess.

    here a quote from Mr.5
    As far as the car, It ran flawlessly (until my rear wastegate decided to stick on me again). Not bad for 84,000 miles though. Every time my engine gets really hot the rear wastegate linkage decides to get sticky and all I need to do is get some motor oil and lube it up. I know that most of it will just burn off but it does help. This didn't happen until the middle of my 5th session though so I just let it cool down and went home.

    Might be worthwhile to try lube it and see if it "temporarely" fix the issue.

    Very good! That's what I was suspecting. Motor oil is a quick and dirty way out of it, but I think a more long-term approach would be to use high-temperature bearing grease. Something like this can hold it up to 900 degrees Fahrenheit:

    Another question for you folks:

    Is it possible to move the waste gate actuator rods by hand? I think it would be good to be able to move the actuators by hand when I am lubricating them to work in the grease better.

    I've not messed with it yet. I had my hands busy with other projects. I've not seen the overboosting issue on the street or on the last 2 autox events that I went to. I have a day off tomorrow so I might dig in the engine bay and try to lubricate the actuators and see if anything feels loose or worse: sticking/binding.

    with INPA you can move the actuators , i am gonna test this on mine .

    I see those screens all over INPA. Are they just diagnosis screens, or are u actually setting the WG positions (in this case) to a different value that the DME will then always use? I wasn't sure, so I didnt move them at all. Manual vacuum FTW.

    The rear turbo, no problem, the front turbo, not a chance without taking a lot of crap out.

    Yep, that's my next line of attack so to speak. Click here to enlarge

    I am glad more people are beginning to use INPA. I should get my ass inline and finish the translation of MSD80 file.

    I just ran a complete diagnostics action plan on the waste gates with INPA. Everything looks good. Actuation went flawless from 0% to 99% on both waste gates.

    So I guess I will try again on another track and get logs out of Cobb when this happens.

    BTW, the overboost DTC recorded 22PSI of boost in the freeze frame information. This is a lot of boost!

    Does anyone know if Cobb removed the boost cap on Stage 2+FMIC maps?

    Any solutions to this? I experienced the same thing this past weekend at Watkins Glen. I have an email in to Cobb, but no response yet.

    vas, you can indeed rotate the actuator rod with a 4 or 5 mm wrench. some toolkits don't even carry this size and you may need to fabricate one (what AA did for me back in the day). we tightened up mine though to fix the wastegate rattle (a well known problem on stock turbos/wastegates), not to fix an over/under boost problem. good luck dude, let me know if you need any more info.

    oddjob,

    Thanks for the info man. I appreciate it. I am going to Gingerman (same track as before) on 26th. This time I'll be prepared to do full logging and I'll bring my tools. I will try to lubricate the actuators before that.

    EDIT: I asked Rob@Cobb if it is possible for him to make me a map that has a boost cap. If I get it before the 26th, it'll be great because I can eliminated software problem.

    Just a quick update:

    I heard from Ian that my issues may be solved with the new maps Jason is working on. I had this issue even with the basic Stage 1 tune, just not as frequently. Like vasillalov, I was seeing 22psi boost numbers at my shift point. For the life of me, I can't replicate this problem on the street, only on the track after several laps. I am experiencing the strange boost oscillations others have discussed and I'm running 4.01. I'll try to keep posting updates here as well as some other forum some of us visit here and there.

    ...at least I am not the only one! Yeah, I am seeing the same thing 22psi and then overboost condition. Rob@Cobb said that Stage 2+FMIC Aggressive is limited to 18.5 psi of boost and that there is no way for the ECU to request more than that. Yet, I regularly see 19+psi of true manifold pressure measured by my P3 Gauge with an analog pressure sensor hooked up to the DVs.

    I hope they resolve this issue soon. Spending money on track days and limping consistently on the track due to overboost sucks. ...at least it is not cooling. My car runs very cool on the track. Coolant temps never went over 210F, oil temps never went over 250F.
