  1. I'm not sure if the app tells you, but there's at most a dozen Analogue inputs, it would have taken less time to look through them all than it would have taken to ask this question :)

     

    Don't forget that there's a number of built-in calibrations, you may not need to use a custom calibration.

  2. The Narrowband sensor is practically useless.

    Ditch it, replace it with the Link CAN Lambda module, or if you happen to have another wideband controller that isn't junk, you can utilise this analogue input for it's wideband 0-5v output.

  3. They can be wired directly to the ECU, but you'll require 4 Digital Inputs.

    Well, actually, technically, you'll only need 2, as you can get away with one front wheel (driven) speed sensor and one rear wheel (driving) speed sensor. If you've already got a gearbox speed sensor hooked up, you already have a driving speed sensor, so you'll only need 1 free Digital Input (and one sensor).

    But more information is always better... :)

    If you can't find those free Digital Inputs, then you can bring that into the ECU via CANBUS.

    So long as the CAN isn't already used for a predefined vehicle specific function, then you can add multiple devices to a CAN network at the same time.

  4. This is a wiring "fault" - typically one of the relays that feeds auxiliary stuff (for example a boost solenoid) is fed from a permanent source, rather than a switched source.

    This is explained really well in the Help both why it happens and how to prevent it, take a look at the section Wiring Information -> Output Wiring -> Auxiliary Output Wiring -> Wiring Auxiliary Outputs -> Avoiding Auxiliary Output Back-feeding

     

     

  5. This is my most disliked change in PC Link.

    Depending on where I'm sitting in the car, I change USB port, I connect to multiple ECUs, so pre-selecting a COM port won't necessarily help to connect to an ECU.

    I kind of understand why it's been added, but maybe Auto mode could be set to check USB first, then pop up the dialog if not found, or have an option to reverse that if the user chooses?

  6. Two options:

    1) increase the PWM Frequency from 500Hz. You may need to change the PID settings slightly due to the higher control frequency.

    2) Change "Run Throttle" to "Quiet" - it'll turn off the motor when the engine isn't running, and it will sit at its natural rest point until the engine starts.

     

    You could also do both.

  7. My understanding is that the ECU works & stores data in Celcius, but just does a visual conversion to/from Farenheit, which might explain some of the oddities when entering values.

    For a fan speed table like this, a couple degrees Farenheit difference will make almost no difference overall.

    Maybe a good opportunity to convert your thinking to Celcius, Lambda and kPa! :D 

  8. Unfortunately no, you can't reassign outputs in G4+, ignition drives have to be in sequence - Ignition 1 through X.

    It is a new feature they've added to the latest release of the G4X firmware, however... not that it really helps you!

    The "spare" "Ignition" outputs on the expansion port can be used as extra auxiliary outputs for various other function, but ignition can't skip over "unused" ignition outputs.

    If you need sequential ignition, you're going to have to re-pin Ign 1-4 on the main header.

  9. There are people out there who will remote tune, but at this point, let's start with "what's wrong", or "what's not working" or "what are you trying to achieve"?

     

    There's a huge wealth of information and advice available here, and part of the fun for me is the learning - and understanding how this all pieces together.

     

    Don't forget and underestimate the Help available in the PC Link software - it's FANTASTIC and exceptionally detailed - the best Help I've ever seen in my time in the software industry.

  10. If the APS and TPS calibration worked, then your throttle is functionally working, so yes, it's probably configuration.

    Share your config file, and people will be able to advise.

     

    However, some questions to maybe help you troubleshoot this yourself...

    "Run when stalled" - is this set to Enabled or Quiet Throttle? If set to Quiet, then it won't do anything until the engine is turning.

    Have you configured your E-Throttle Target table - you may find it's full of 0s.

  11. I would strongly recommend against this - but instead just install a Flex Fuel sensor - and let the ECU take care of it.

     

    Also, if the quality of your "E85" fuel changes - which it likely will - again, the ECU will just take care of it. And, in that period where you've got a mixture in your tank and lines - the ECU takes care of it.

     

    Ideally you want as little human interaction with regards to the core fundamentals and engine protection - instead add the relevant sensors and let the ECU do the heavy lifting!
