    Simon reacted to Richard Hill in turbo potentiometer   
    As Simon mentioned, you will need to wire the output of the potentiometer to a spare analog input (with the other two pin on the pot wired to +5 Volts and sensor ground).  AN Volt 4 is shown in the example below.  Then select a spare Cal, I use 4 as it is a 2 point linear cal instead of a table.   

     
    Next, in the cal settings choose % as the output unit.  IT doesn't have to be %, you could leave it as 0-5 Volt raw.

     
    I would start with open loop boost control, as you will need to find out what duty cycle is required to achieve a particular boost target.  

    In the wastegate %DC table, select the an volt input as the y axis and populate the table with the %DC required for each boost step required.  In the example above I have used 50% duty cycle as maximum boost. 
     
    That is the easy bit done!  I would suggest looking at the help file for information about setting up boost control and when you are happy with the open loop mode, progress on to closed loop boost as this will give you more consistent boost levels which will be met and maintained by the closed loop algorithm.
     
    Regards,
      Richard.

    Pot will need a 5V supply and a ground and then the signal will be wired back to a AN volt on the ECU. (Just like wiring in a TPS sensor)

    Can you post a new log?  I tested the fix using your original map and tried to reproduce all conditions in your log and couldnt get the ecu to add the odd CL step when it exited speed hold or entered hold timer like you originally reported.  So it was me that signed it off as fixed.  There does appear to be another similar problem that some other users are reporting that might be what you are seeing now.  I would like a log to confirm.

    Simon reacted to cj in EZ30D JDM swap into Subaru 2.5rs   
    The trigger signals themselves are the same between the EZ30D and EZ30R so you should be able to use the EZ30 trigger mode for trigger1 & 2, and then set the VVT type to Off. 
    Only thing that might be an issue is the older 30D's only had a single cam sensor, whereas the newer ones have one per bank. The bank's both use the same 3 tooth cam wheel but the offset vs the crank is different for left and right. I'm not sure if the older model used the same offset as the left or right cam - the left is supposed to be trigger 2 on the EZ30R's. I suspect the ECU will sort this out for itself but you'll want to check the timing before you fire it up (which you should do anyway, just make sure you actually do it on this engine.
    FYI the crank is the 36-2-2-2 and the cam is 3 tooth even spaced but cant manually put in complex numbers like the crank has.

    Simon reacted to mapper in Questions about the capabilities of a WRX9+ G4+   
    Guys relax a bit. 
    I've mapped and I'm supporting several 600-800hp 2.0 to 2.3l time attack engines/cars with a Link ECU and multimap strategy.  Such an engine runs usually for 5000 race track kilometers until a rebuilt is needed. That's a similar distance to a 24h race.  I like to answer your question.: 
    All LINK ECU use the same PC-Software and the same Firmware. The main difference between all LINK G4+ ECU's is only the hardware.
    your tuner should tune the main Fuel and ign Maps from the lowest to the highest boost levels. There are 3 main Boost Maps in the LINK ECU. You can additionally span one of the axis of the Boost Wastegate or Target table to a driver Rotary Switch. So it's possible to have up to 33 different boost maps, which all can be switched on the fly. 
    On top of that, you can activate 4D fuel and ignition tables on one or several of the boost maps. This allows trimming Ignition and Fuel on some maps if you or your tuner like to do that. 
    The Link Ecu is really flexible. Usually, the only limit what you can do is the creativity of the tuner. 
    As an example, we installed 3 rotary switches in a Time Attack/ Hillclimb car.  One 12-Position Rotary Switch is used to choose between 12 different torque maps (mainly altered by boost strategy). The Launch RPM can be chosen over another 12-Position Switch, depending on whether and Track conditions. And lastly, we have a 3-Position Rotary Switch to choose one of 3 Drive by wire Throttle Maps.  
    For engine Safety, we set up Limits for too low and to high Coolant temp, Oil temp, Oil press and Fuel press. We are also using full time closed loop lambda and sending a lot of Data over a custom CAN. 
    As you see, the LINK is a very capable system.  But as every ECU, it needs a capable tuner to use it properly.

    I think on the nissan the injectors are hot fed. So will have a permanent fed to them direct from the battery.
    Generally when a drive is damaged it will short to ground but I would not then expect a back feed.
    But I do think there is drive damage that will need to be repaired.

    You will first need to confirm if the sender has been wired back to the ECU and if it has what Volt input it is on.
    You can then set up a cal for that AN volt channel. You will need to know the Voltage to pressure values for a couple of points in the senders range.

    Simon got a reaction from Ted in Aux injectors on the G4+ plugin   
    Ideally avoid wiring the injectors in series, If high impedance then you can do up to 3 injectors per drive in parallel.
    Low impedance would be a push at 2 per drive. 
    Assuming 8 injectors then primaries on to drives 1 and 3 and then the secondary on drive 2 and 4. Two injectors per drive. 
    Then run as group staged

    Simon reacted to AlexLSX7 in Slow reacting   
    I have just done some testing on my Dell laptop which only has 2 USB ports. One is USB 3 (Blue) and the other is USB 2 (Black). I have been using the left USB 3 port as it was easier to plug in while in the car. I swapped it over to the USB 2 port on the other side and i now no longer have any lag what so ever in the software. It was really bad before,.
    I have found this the case many times in Windows 7 and Windows 10. A lot of devices just dont work well in a USB 3 port unless they are USB 3 themselves. Most likely a driver issue.
    Check your laptops and see which port you are using as it may be the same case for you too.

    No issue to retain the paired wiring, The benefit of individually wiring the injectors is you can then do individual cylinder trims and the firing of the injectors is timed correctly to the cylinder position (this is also adjustable).

    Simon got a reaction from M1tch in Can I adjust speedo?   
    Its a function in the ECU. On the Digital input there is a calibration figure. Adjusting this allows for different wheel sizes.
     
    A Digital Input may be connected to an electronic wheel speed or vehicle speed sensor (typically located near the output of the gearbox, or as an output from the vehicle dash board) to enable speed to be calculated.  These Digital Inputs can then be used to configure the Driven and Non-Driven Speed Sources.
     
      The Calibration number allows the ECU to calculate speed in km/h.
     
      Note:  In some cases erratic speed signals can occur due to unusual speed signal shapes.  Changing from Rising Edge to Falling Edge or vice versa may help with this problem.  This problem usually presents as random spikes of increased speed.
     
      Set-up Procedure:   The Calibration number is the number of pulses received over a 100 m distance.
     
      Method 1:  Drive the vehicle at a known speed and adjust the calibration number until the Vehicle Speed Runtime Value displays correct.
     
      Method 2:  Wheel Speed Sensors Only.  Calibration Number = (Number of Sensor Teeth / Wheel Diameter) * 31.83.  Note that wheel diameter is in meters (m).
     
      Typical values for speed calibration numbers range from about 170 to 280. The maximum frequency the digital input can accept is 500 Hz.
     
     
      Note:  Wheel Speeds can be checked in the Runtime Values Digital Inputs tab

    Most likely a mistake during packaging missing putting one jumper in.

    The jumpers are relatively common and often used in PCs so a very good chance one can be found locally.

    Starter Control
     
    Starter Control provides ECU managed operation of the Starter Motor.
     
    There are two requirements for starter control to function:
     
    · A Digital Input Function must be setup as Start Position. This could be a conventional key activated ignition switch or a push button. and
    · An Auxiliary Output Function must be setup as Starter Solenoid. This output should be connected to starter solenoid relay.  
     
    Starter Control Settings
     
    Start Switch Mode
     
    Selects the mode of starter control. Options available are:
    · OFF - No starter motor control by the ECU. · Test - Use for testing input/output functionality only. When Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. No other conditions are checked, this could potentially lead to starter damage, engine damage or personal injury if operated at the incorrect time. · Normal - Behaves the same way a typical vehicle starting system.  The key is turned and the engine will crank until the key is released.  However it offers the added protection of preventing the starter being engaged at a high engine speed and the option to disable starting if the vehicle is not in Park/Neutral or is immobilised. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park  Lockout are met AND Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. The auxiliary output will stay active until the Start Status turns off OR the the Deactivation RPM is reached. · Start/Stop - Allows the use of a single button for both starting and stopping the engine.  When the engine is stalled, pressing the button will crank the motor over.  Once the motor is running, pressing the button again will stall the engine.  This mode is suitable for a single start/stop button on the handle bar of a motorbike or jet ski. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park  Lockout are met AND Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. The auxiliary output will stay active until the Start Status turns off OR the Deactivation RPM is reached. Once the engine is running, if the engine speed is above the Deactivation RPM AND the Start Status becomes active the ECU will apply a 100% Fuel and Ignition cut to the engine. · Touch Start - Allows a starter motor button (or key) that can be momentarily pressed to start the engine.  The driver taps the button and the ECU will take care of starting the engine.  Typical applications for Touch Start mode would be remote starting or a jet boat. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park Lockout are met AND Start Status is momentarily active the ECU will activate the Starter Solenoid Auxiliary Output until the Max Crank Time is met or the Deactivation RPM is reached.  As of firmware version 5.5.6, pressing the start button again while the engine is running will stop the engine.  
    Starter Deactivation RPM
    Specifies the engine speed (RPM) above which the Starter Solenoid Auxiliary Output turns OFF.
    Use Anti-theft Lockout
    An option to make the Starter Solenoid Auxiliary Output conditional upon Anti-theft status. If set to Yes and Anti Theft Status is Active the Starter Solenoid Auxiliary Output will not function.
    Use Neutral/Park Lockout
    An option to make the Starter Solenoid Auxiliary Output conditional upon Neutral/Park status. If set to Yes and Neutral/Park Status is OFF the Starter Solenoid Auxiliary Output will not function.
    Max Crank Time
     
    Used only on Touch Start Start Switch Mode, this is the maximum amount of time the starter will be allowed to crank if the engine does not start.
     
     
    Starter control Examples
     
     
    Example 1:  Normal Mode with Anti-theft
     
    Assume Starter Control is set up as:
     
    Start Switch Mode = Normal
    Starter Deactivation RPM = 600 RPM
    Use Anti-theft Lockout = Yes
    Use Neutral/Park Lockout = No
     
    With the above settings the ECUs Starter Control would activate the starter motor if:
    · Engine speed is less than 600, and · The anti-theft signal is off and · The driver presses the start button (or turns the key).  
     
    Example 2:  Start / Stop Mode with Neutral / Park Lockout
     
    Assume Starter Control is set up as:
     
    Start Switch Mode = Start / Stop
    Starter Deactivation RPM = 550 RPM
    Use Anti-theft Lockout = No
    Use Neutral/Park Lockout = Yes
     
    With the above settings the ECUs Starter Control would activate the starter motor if:
     
    · Engine speed is less than 550, and · The Park/Neutral signal is active and · The driver presses the start/stop button.  
    With the above settings the ECU would apply a 100% cut to both fuel and ignition if:
     
    · Engine speed is greater than 550, and · The driver presses the start/stop button.  
    Note: The fuel and ignition cut will remain until engine speed is zero RPM.
