  1. Looking for advice on turbo onset improvements - closed loop PID control

    in G4x

    Posted

    Hi there - attaching a log and my tuning file  just looking for some advice if there is anyway to improve the turbo spool speed on this setup? Its set into closed loop and the logs only show its goes into stage2-3 really late, and my WG DC% is 100% (even with a 14psi spring).

    Logs look like I never reach stage3 PID control, just stage1 and 2, and I never reach boost target. I'm wondering if i start this at a lower activation point (say 100kpa vs 110kpa), and if I need to adjust the P, I, and D to get me there

    Any help greatly appreciated

  6. TTX Cruise Control

    Hey Adam

    I have a wiring diagram somewhere that shows operation - and my car is located in CHCH. So if it ever boils up to the top of the priortiy list, happy to help with the hardware already installed.

    How would I go about setting this up on the keypad? I have one that has spare buttons.

  7. TTX Cluster Oil pressure MIL

    Hey Vaughan

    Yes so the behaviour so far i can understand:

    • switch is set to low - MIL on, set "test to ON" - MIL on
    • switch is set to high - MIL off, set "test to ON" - MIL off
    • switch is set to high - MIL off, set "test to PWM" - MIL on

    Switched my oil pressure switch out of the TT MK1 for a combined oil and temp sensor - this is wired into An Temp3 and An Volt 10, this works very well.

    The stock car had an oil switch that would turn the oil MIL off the cluster when the pressure reached a certain point. I was trying to mimic this using a spare ignition pin (Ign6), so when the conditions are correct the MIL turns off.

    If I set this pin to low, the MIL is on, if i set it to high, the MIL is off - however, the "test" function does nothing, for some reason I cannot trigger it to turn on or off? Any help is greatly appreciated

  9. TTX Cruise Control

    Are there any plans to support native cruise control switch on the TTX in a MK1 TT?

    Pins required are 38/57/75/76 to operate off the stalk, but these are NC on the wiring pinout for the TTX? Really would love to be able to have stock cruise control.

  14. Ethanol Sensor setup - G4X TTX Plug and Play

    in G4x

    Posted

    Hello

    Setting up my ethanol sensor on my 1.8T Audi TT with the TTX Plug and play ecu. Trying to get my head around pinouts for it. Currently setup as follows:

    1. 12V from Aux 6 (Pin 64) - triggering on "ignition switch = Active"
    2. DI9 for signal input (Pin 28) - Pull-up "OFF", Active Edge "Falling"
    3. GND back to Pin51 (old O2 Sensor GND)

    Unit reports "FAULT" on the live runtime values page for the sensor under DI internal status - no fuel in the sensor as yet.

    • Are my pinouts going to work, or am I overthinking this and should run the 12v off a switched live point instead?
    • Are the settings for the sensor correct? (Small VDO sensor from MSEL)

    Cheers
