  1. Aim MXS Dash displaying incorrect Fuel Pressure on display

    in G4+

    Posted

    I've just updated RS3 to 3.64 and updated MXS dash to 2.40.77 and problem still persists.

    At this stage the following:

    Fuel pressure 2 is working

    Fuel pressure 1 is not working / displaying (-)

    Boost pot is not working / displaying (-)

    Diff F pressure is not working / displaying (-)

    Turbo speed is not selectable / visible

     

    Thanks for the help. Much appreciated

    So you havent changed anything in either of those 2 files?  You've left the cal 5 set up in kpa? I just loaded your map in an ecu and the CAN output is correct.  Is FP1, FP2, and diff FP all showing the same problem in the dash?  What firmware does your dash show in RS3?

    Apologies, I had loaded the incorrect aim file. 

    Fuel pressure 2 is working now. Although, fuel pressure 1 is not displaying anything (-). Boost pot is not displaying a figure either (-). Turbo RPM / Speed sensor off efr turbo DI7 is not visible.

  10. Quick tune - "No WB Signal

    in G4+

    Posted

    I'm trying to quick tune my idle as I've just installed a new FPR, to be able to drive my car to the tuner. Although I'm having an issue trying to get it idling. It is constantly stalling.

    When I select quick tune, auto or manual - I get an error "No WB Signal". I've checked my can lambda and it is indeed connected to the ECU. Lambda 1 in runtime values is "OK"

    How do I go about getting this working?

  11. Aux output to fuel pump

    in G4+

    Posted

    I'm running dual walbro 460's radium hanger -8an feed, -6an return.

    They're currently both hardwired on the same oem fuel pump wire trigger. This would mean the both pumps run at 13-14v constant and creating too much pressure. (I have a new FPR otw to try and bypass more fuel)

    I've done a bit more research and;

    I can have 1 pump hardwired to the oem fuel pump to run at 13-14v constant and the 2nd pump hardwired to a link aux output to run the 2nd pump at 13-14v constant when injector dc rises.

    Or I can hardwire both pumps at 10v at low load and 13-14v high load. Does the link ecu have tables I can edit to control the oem fuel pump relays? At certain loads / rpm's? I thought this would be an advantage as it will allow the pumps to run less power / cooler at idle / low load?

     

  12. Aux output to fuel pump

    After a bit of research, the stock Evo wiring should be running the fuel pumps at a slower speed when at low load and engaging fuel pump relay 3 at high load. Is load RPM based or based off the stock fuel pressure regulator?

    I’ve deleted the stock fuel pressure regulator due to an aftermarket intake manifold and installed an aftermarket fuel pressure regulator but can’t seem to get the pressure down whilst idling

  14. Aux output to fuel pump

    in G4+

    Posted

    I've 2 fuel pumps and I want to stage the 2nd one, as my fuel system is creating too much pressure whilst my FPR is wide open.

    A bosch pressure sensor is on the fuel rail to monitor pressures.

    I want the ecu to turn on the 2nd fuel pump when fuel pressures drop below a certain point.

    Can AUX 11 on evolink g4+ achieve this?

    Would the attached wiring diagram work?

  16. G4+ E-throttle set up error

    in G4+

    Posted

    I'm in the middle of setting up E-throttle on my G4+ and am getting an "error 5: TPS (Main ) Movement zero".

    Pedal has been calibrated, although when trying to calibrate the electric throttle body an error occurs.

    When I enter "Set up" mode with "run throttle" mode the T/B opens 100%. I then select to calibrate throttle body, it tries to calibrate from WOT / open the T/B wider and then comes up with  "error 5: TPS (Main ) Movement zero".

    TP Main & TP Sub both have voltage readings and change when I manually open & close the T/B.
    I've gone over the wiring and can't seem to work out what's going wrong. How do I rectify this issue?

  18. How do I add more inputs to G4+ when expansion connectors are both full?

    in G4+

    Posted

    Thank you very much. This is basically what I've come up with:

    I'm short a 1x Temp sensor & 2x pressure sensors. These are all liquids and I will wire these to my AIM MXS.

    AN VOLT    
    NAME PART INPUT
    MAP SENSOR - onboard Link onboard AN VOLT 1
    Fuel pressure @ surge tank BOSCH COMBI TEMP/PRESSURE SENSOR AN VOLT 2
    TPS 2 (OUT) BOSCH ELECTRIC T/B  AN VOLT 3
    EFR Turbo speed sensor   AN VOLT 4
    POWER STEERING SWITCH OEM AN VOLT 5
    FUEL RAIL PRESSURE BOSCH COMBI TEMP/PRESSURE SENSOR AN VOLT 6
    TPS 1 (OUT) BOSCH ELECTRIC T/B  AN VOLT 7
    OIL FILTER PRESSURE BOSCH COMBI TEMP/PRESSURE SENSOR AN VOLT 8
    PEDAL POSITION LOW BOSCH ELECTRIC PEDAL AN VOLT 9
    PEDAL POSITION HIGH BOSCH ELECTRIC PEDAL AN VOLT 10
    LCA2 ZEITRONIX FLEX SENSOR AN VOLT 11

     

    AN TEMP    
    NAME PART INPUT
    ECT OEM AN TEMP 1
    OIL FILTER TEMP BOSCH COMBI TEMP/PRESSURE AN TEMP 2
    IAT @ MANIFOLD MOTORSPORT IAT AN TEMP 3
    FUEL TEMP ZEITRONIX AN TEMP 4

     

    AUX    
    NAME PART AUX
         
    BOSCH ELECTRIC T/B MOTOR (+) BOSCH ELECTRIC T/B AUX 9
    BOSCH ELECTRIC T/B MOTOR (-) BOSCH ELECTRIC T/B AUX 10
    TRANS OIL PUMP   AUX 11


     

  19. How do I add more inputs to G4+ when expansion connectors are both full?

    in G4+

    Posted

    AN volt 2 - maf sensor is not in use as I'll be utilizing onboard map sensor and will be used for fuel pressure sensor.

    AN volt 4 is not in use as I have a link can lambda and will be used for an EFR speed sensor. I believe it is Volts.

    AN temp 3 is currently used for MAF / intake temp

     

    Aus evo ix didn't have:

    MAP sensor / AN volt 1

    or IAT / AN temp 2 from factory.

    Can I utilize these if there are pin outs on the G4+?

     

     

    Ok great. I think I'll be able to manage to fit all my sensors without the need to upgrade ECU.

     

     

  20. How do I add more inputs to G4+ when expansion connectors are both full?

    I've an Evo 9 with a G4+ - E-throttle. Converting to Bosch DBW and have used up all the inputs on expan. 1 & 2 for the electric T/B & pedal. I also have sensors I'd like to connect to the ECU such as Temp / pressure sensors for fail safety. How do I go about adding more inputs to the G4+? Do I need another unit to add more inputs?

    I also have an AIM MXS digital dash that accepts sensor inputs, can the input information collected from the AIM MXS be streamed to the Link G4+ to allow for fail safety?

  22. How do I wire 8 injectors individually to G4+ Evo 4G63

    in G4+

    Posted

    Basically I ran out of fuel / injectors at my last dyno tune. 2000cc Bosch injectors were at 90-95% duty cycle.

    I've since upgraded the system and am now running 2x 2200cc Bosch injectors per cylinder.

    The car is an Evo 9 - 4G63 so originally only has 4 injectors and I'd like to be able to wire them in to my existing Link G4+.

    And I'm running E85 @ 43.5psi base fuel pressure. I hope this makes sense!
