Hi William. Version 1 to 6 WRX all trigger in the same way so this shouldn't be an issue.

Hi Mike, We do a 150psi 1/8 BSP-T oil/fuel pressure sensor. Please email [email protected] for pricing information. Otherwise, any correctly rated oil pressure sensor that gives a voltage output 0-5V proportional to oil pressure can be used. Honeywell make nice sensors, but these can be quite expensive.

Hi All, We are very sorry about this issue and we know it's a major problem. Please be assured that we have poured hundreds and hundreds of hours into development of a logging analysis software package. This is making excellent progress and a beta version will be released in the near future. Regards, Phil

In the back section of the manual http://www.linkecu.com/support/documentation/g4-engine-management-documentation/NissanGTS you will find a pinout and pin function information. You can use this as a guide. The manual does not show all of the power and ground connections that are also critical. Basically you should only remove something if you are 100% sure you don't need it. Looking on google for a pinout for your loom might also be of use.

Hi Brett, The G3 doesn't support low impedance injectors directly, although you can run them with ballast resistors. Neither injector can be considered better. It's just more common for high flow injectors to be low impedance. Regards, Phil

A likely reason that it starts in row 200 is due to the fact that when its starting its not pulling infinite vacuum, where a throttle position sensor can go to 0% if this makes any sense? Regards, Phil

Hi Chris, We recommend the Innovate Motorsport LC1 Wideband Controller and Sensor package. This can be purchased from us directly if required. The LC1 has two configurable analogue outputs; one of these can be wired to an analogue input on the G4 ECU. Once connected to the ECU via PCLink you will need to configure the calibration of the input voltage to read the correct AFR, the calibration is listed in the LC1 manual. Closed loop lambda via wideband can be configured from the 'Closed Loop Lambda' menu inside the 'Fuel' menu. You have a number of lockouts and closed loop settings available to optimize the performance of the system. (see the help section within PCLink for further information on how these all work). Once configured you can adjust the AFR target table. The numbers in here represent the AFR that the closed loop system will target. The second main advantage of running a wideband sensor is to setup a Limit system based on AFR, this can be configured to protect the engine against a failing fuel pump. As an example you might require that the AFR stays richer than 12.2 at 100kPa of boost. If this threshold is exceeded for a defined amount of time, the ECU will bring on a rev limit to protect the motor from detonation due to lean mixtures. Regards, Phil

Hi Kerrie, Read through this and let me know if it helps: The Nissan 360 Opto Trigger Decoding Trigger Mode is designed for use with Nissan optical Crank Angle Sensors (CAS) that have 360 evenly spaced slots and 4,6 or 8 different width slots. Digital trigger decoding uses all of the 360 slots to achieve precise engine position calculation. Of the 4, 6 or 8 slots, one will be wider than the others. This 'Widest Slot' is used by the ECU to determine the engines position in the firing order. As the width of this slot varies depending on the exact CAS used, an automated setup procedure has been provided. Note: THE ENGINE WILL NOT START when Test ECCS Sync is turned ON. Setup Procedure: Setup ECCS Trigger Decoding as follows (Read the entire process and ensure you understand before starting): 1. Ensure the 360 slot signal is wired to the ECU's Trig 1 input. 2. Ensure the 4,6 or 8 slot signal is wired to the ECU's Trig 2 input. 3. Switch the key on, do not start the engine. 4. Connect to the ECU using PCLink. 5. Ensure all Configuration options are correct. 6. Under the Fuel heading, select Fuel Setup. Set Injection Mode to OFF. This will prevent the engine from starting. 7. Under the Triggers heading, select Trigger Setup. 8. Select Nissan 360 Opto as the Trigger Mode. Note that this will initialise all trigger inputs to default values. The default values are as follows: · Trigger 1: · Trigger 1 Type = Opto/Hall Sensor (Not adjustable when Nissan 360 Opto Trigger Mode selected). · Trigger 1 Pullup = ON · Trigger 1 Filtering = Level 1 · Trigger 2: · Trigger 2 Type = Opto/Hall Sensor (Not adjustable when Nissan 360 Opto Trigger Mode selected). · Trigger 2 Pullup = ON · Trigger 2 Filtering = Level 1 9. Select the Engine Type. Note that all this does is place a suitable number in the Trigger Offset value to make setting the base timing faster. If your motor is not listed, select Other. 10. Select the resolution mode. Select Low Res Mode = ON for engines with aggressive cam shaft profiles or lightweight flywheels. This will provide improved timing stability on engines that have large variations in CAS rotation speed per revolution. 11. Set Test ECCS Sync to ON. This will put the ECU into a special mode where it will automatically calculate the position of the widest slot. Note that in this mode the ECU will disable both fuel and ignition. Enabling this function will also initialise the ECCS Widest Slot value to 0. 12. Click on the Triggers Runtime Status tab in the bottom section of the PCLink screen. The following runtime values will be displayed for diagnostic purposes: · Trig 1 Signal - Will display as YES if the ECU detects a correct 360 slot trigger signal. If this value displays as NO during cranking, check sensor output and wiring. · Trig 2 Signal - Will display as YES if the ECU detects a correct 4, 6 or 8 slot trigger signal. If this value displays as NO during cranking, check sensor output and wiring. · ECCS Sync - Will display as YES if the ECU is using the widest slot correctly for a synchronisation signal. 13. Crank the engine. This will start the widest slot calculation procedure. This procedure will take about 4 seconds. If the procedure executes correctly, the following should be observed: · The Trig 2 Signal run time value will indicate YES first, closely followed by the Trig 1 Signal runtime value indicating YES. · The ECCS Sync runtime value will indicate YES when the process has finished. · ECCS Widest Slot will change from zero to a value indicating the width of the slot (typically between 5 and 25). 14. If after 10 seconds of cranking the ECCS Widest Slot value is still zero, an error has occurred. Recheck all trigger wiring and test the CAS output. If this is OK, repeat the entire procedure. 15. If the process completed successfully, switch Test ECCS Sync to OFF. 16. Remembering that the Injection Mode is still set to OFF, crank the engine and check that a stable RPM is obtained and the value is consistent with a typical cranking speed. 17. Set Injection Mode back to the desired option. 18. If all is OK, perform a store to permanently save all settings to the ECU. 19. Set the base timing before attempting to start the engine (DO NOT JUST TRY STARTING THE ENGINE!).

Hi, We don't have the trigger offset information here, but somebody else may be able to help you. Best bet is to get a timing light and calibrate it yourself. By dash you mean a Link Dash or the factory dash? In the case of a factory dash you can 'T' into the electronic speedo wire and run this to a Digital Input on the ECU. A calibration number will need to be adjusted to get the ECU reading the correct speed.

A Potentiometer generally refers to a dial with an analogue voltage output. A 3 position rotary switch can be wired with resistors to an analoge channel just how Matt has done. The G4 has configurable axis so it doesnt matter how many switch positions you have.

http://www.linkecu.com/support/documentation/g4-engine-management-documentation/NissanGTS is the installation manual for the ECU you will most likely recieve. Section 4.3.1 Nissan Skyline GTS/GTR of the manual shows the expansion connector. There are two avaliable DIs and these can be used with the additional purchase of an expansion loom. Looking again at that switch, I cant tell you exactly how it works as there is no datasheet for it on the web address you gave me. I'd assume it would work if there are three pins on the back of it. Otherwise your local electronics store will sell something that will work. This does confirm that you will be able to run three seperate boost maps.

Scott, Yes the G4 is capable of running a V12 engine using a wasted spark setup and group fire fuel. Please provide the engine code so we can confim that the G4 will or will not decode the engine position sensor signal. Regards, Phil

The first switch would be ideal, only disadvantage I can see is that it would consume two digital inputs. If you are running a Storm you only have four in total. The other more complicated option is to wire the switch to an analogue channel with a special arrangement of resistors around the switch. Then setup two vitual aux channels to determine the state of the switch, and then trigger the boost tables off the virtual aux states. If you want to go down this path, please let me know and ill provide you with the information to set this up.

Hi Brad, I wouldn't block the idle valves off as these often bleed some air when unplugged. Assuming the car wasn't tuned with the leak your best option is to fix the leek. After your repairs it would be advised to get the tune checked by your nearest Link Dealer. Regards, Phil

Hi Shaun, You have two main option; either an Analogue Potentiometer, or a two position switch. The analogue potentiometer would allow you to adjust the boost over the range you configure. The switch allows you to select between two boost settings. Regards, Phil

Good to hear you have it sorted.

please email me at [email protected] for further support

Hi Ferenc, Sorry for your frustration, this is on our to do list. Regards, Phil

Hi Brain, To switch an AUX off a DI, you select 'DI Value1 = ON/OFF', and enter the DI channel you require in the box beside it. Regards, Phil

Hi Allen, With 100% DC in the fully closed position it would suggest that the motor is wired with the incorrect polarity. Is there anything else you need help with? Regards, Phil

can anyone supply me with a .pcl file base map for the 3sge ? even if its just a roughie i just need 2 get my motor started. cheers

I've had a look at the information you have provided. Seems like a good idea, but i disagree with "Again my understanding is this type of system is superior and less costly then a "knock box"." for the simple fact that 99% of vehicles on the road do not run CDI from factory which means this would need to be installed before even considering the costs of the knock controller. Installation would also be far more difficuilt as each spark plug needs its own interface, where with the standard method one knock sensor can be used to detect individual knock on up to four cylinders using data windowing techniques. We appreciate the suggestion but I don't think any development will be done on this anytime in the near future.

Hi Daniel, Interms of pricing of a G1, your best bet is to check www.trademe.co.nz and see what they sell for on there. The manual for the G1 GTSLink is here: http://www.linkecu.com/support/documentation/g1-engine-management-documentation/gtslinkinstructionmanual Regards, Phil

Hi, Sorry for the delayed reply. Datalogging is fully active when the G3 ecu has been upgraded to run G4 firmware. Please contact [email protected] for further information on this. Regards, Phil
