Safety Boost over power boost controller?

    So gizzmo boost controller is set to .9 bar but when excellerating the gizzmo controller will only read a max of say .4 which is about safety boost levels from memory...

    so ecu safety boost over power a controller? i would said no since controller should replace that stuff?

    shows how tired i was this morning lol
    accelerating not excellerating hahahab

    In conclusion its not boosting as high as what the boost controller is set to... question is why

    My gizzmo ebc is doing this as well set to 1 bar but won't boost over 4.3psi. Has been suggested to me by my mechanic that one of the actuators on the turbos is stuck open.

    well i had a boost like from the passenger actuator to the controller break which has since been fixed... but i thought perhaps that caused it to go into safety mode.. thus ill need to reset it.

    Unplug the safety boost soleniods when you have an electronic boost controller fitted. Leave them be when a manual boost controller is used.

    and they are where exactly..

    still learning the indepth parts of TT's

    this unit?


    and by unplug you mean pull out or just electrically unplug

    also for mods, link broken in tech section

    On each side of the plenum about the centre. There are 2 black plugs one on each side that look NOTHING like any of the other plugs in the engine bay. Very square.

    Unplug them.

    Factory boost solenoid plugs are big square, black and orange plugs next to the plenum on each side above the turbos.
    They need to be disconnected and tied/taped up out of the way.

    When adjusting the gizzmo units, I just want to make sure a couple of things are clear.
    1. Adjusting duty and gain settings are percentages (%), not actual values.
    2. Adjusting duty sets boost level
    3. Adjusting gain sets how quickly boost will climb.

    Following these instructions, you can set it up doing the following.
    1. Choose preset channel of choice.
    2. Set duty and gain to 0.
    3. Do several WOT to redline runs and watch what max boost is achieved.
    4. Adjust up DUTY ONLY by 5 or so units. Repeat 3 and 4 until maximum boost desired is achieved.
    5. SLOWLY adjust gain up to set how quickly boost will come on.... BUT be careful or spiking as from my experience they can spike pretty badly if the gain is set even 1% too high.

    If your cars are not boosting, you may have to do this process from the start.
    Or it could be as simple as having the EBC on the wrong preset... simply scroll through all the presets to see if it was bumped and ended up on the wrong one??

    Possibly even need to reset the ecu and do all of the above to make sure everything is working harmoniously.

    Hope any of this helps.

    had a quick look and couldnt see anything bolted to the support bar on the plenum.

    Engine has been rebuilt at a point etc so i was pretty sure they were all removed etc already...

    can has been tuned so just need to get it back up to the full tune

    get a hdi, set and forget. I hate those ****ing "tunable boost controllers" my greddy really pissed me off. love just setting it and holds it every time.

    such a relief with the hdi.

    no reason why an electronic gizzmo wont be set and forget... its something else thats causing the issue

    plus even with hdi you should still need a tune

    so you dont need to set gain and duty cycles values? hdi you dont need that you set the boost and it sorts the rest out really well.

    my car is tuned for stock injectors the greddy just would chop and change day to day.

    just my 2 cents as i had the same issue.

    now if you dont have safety boost solenoids then it as to be something else yeah?

    Error 34 for det sensor even after a resister is put in so wiring maybe? but if thats putting it in safety mode with no solenoids should it matter?

    No it shouldn't matter, boost wouldn't/can't drop, tune will change tho (assuming stock ecu).

    Make sure all your plumbing is done correctly.

    Maybe your solenoid is stuffed.

    HDI is like a manual boost controller, but you can set it from in the cabin.

    Spikey, spikey.

    i have a 2 stage manual boost controller i might put in to see if it makes a difference...

    Pretty sure its not man. mine doesnt spike at all. holds dead steady

    just confirmed this with hdi. Below 1.5 bar it is closed loop. above 1.5 bar it is open loop and operates like a manual boost controller. EVO dual stage. this is limited by the internal map sensor in the evo dual stage.

    They are working on reprogramming the boost controller to read the 2.4 bar map sensor they have released. so it will operate closed loop to 2.4 bar. (experimental)
