It exists.
That is what the Dead time table is for.
-
Edit z is a way of adjusting values whilst the engine is not running.
Suggest having a read or this manual should cover most things.
-
Knock detection equipment is almost a must have for tuning safely. It doesn't have to be connected to the ECU. But should always be monitored whilst tuning. If your tune is way off no amount of correction from the knock control is going to save your engine.

Prim is active when engine temp is under the prim temp. It gives a quick opening of all injectors at key on. Typical value is 20 deg.

Hi Dennis
We are still pushing towards a release for this application but it is requiring a substantial amount of development.
There is every chance we are still over 6 months away.
-
Yep you got it. The input to the igniters can be paralleled up.
This will give full current to all coils but still fire the two leading coils together.

With both G3 and G4 PCLink open (G4 PCLink connected), begin setting up the ECU using your existing G3 map. This must be done manually noting the following:
-
All table axis must be configured to exactly match the G3 axis. The copy and paste function works well between tables once the axis have been correctly setup.
-
G3 ECUs have a parameter named 'Dwell Edge'. In G4 ECUs this is now called 'Spark Edge'. A rising 'Dwell Edge' is the same as a falling 'Spark Edge' and a falling 'Dwell Edge' is the same as a rising 'Spark Edge'.
-
G3 ECUs have channels named Load Input. G4 ECUs have renamed these as AnVolt channels. This causes G3 AnVolt channel numbering to differ from G4 AnVolt channel numbers. For example Load Input 1 becomes AnVolt1, Load Input 2 becomes AnVolt2, Load Input 3 becomes AnVolt3, AnVolt1 becomes AnVolt4, AnVolt2 becomes AnVolt5... etc.
-
AFR correction must be turned off on the G4 firmware.
-
Fuel Equation must be set to Load = MAP on the G4 firmware.
-
If the car fails to run, it is very unlikely to be a hardware fault. Please double check all settings.
-
G3 LinkPlus Aux11 is not supported by G4 firmware.
-
After setting up the ECU perform a 'Store'.
-
It is recommended that the engine is then checked by your Link dealer to ensure everything is operating correctly.
-
-
The map can be copied and pasted across.
Just make sure that the axis setup is the same on the table being pasted into.
-
What is happening is that the two coils being run off the single channel are only getting at best 3 amps of current. Causing a very week spark. Only solutions are another igniter so each coil has its own igniter channel or to go to a dual post coil as you mentioned.
-
To get the overlay table to cover a wider range you will need to adjust to bigger steps between rows.
As the the trims are not large you don't need the fine steps between rows.
The Knock settings will need adjusting to find a good base level.
I would really suggest getting the tune done professionally if at all possible as the results if a mistake is made will not be pretty.
-
The main problem will be you will have to run the accel fuelling off MAP which is often not as good as TPS.
Not sure of an alternative TPS sensor but im sure someone else will be able to help on this one.
-
If you have free outputs these can be wired direct in to the short loom between the adapter and LEM
Effectively disconnecting the outputs from the adapter.
-
I would suggest using the distributor modified to fit a trigger. What sort of trigger is open but I would suggest 24-1 or maybe fitting nissan 360 opto trigger disk and pickup.
-
If you have a look at the attached file it will give some idea. It is a G3 file so will need to be opened in 3.40 PClink.

Hi Lawrence.
I would suggest getting the tune sorted first and then work on acceleration fuelling.
As you have a GTR I am assuming that you have retained the 6 butterflies.
This requires a different fuelling configuration to most.
I would suggest spanning the main fuel table over TPS and then running a overlay table based on MGP.
This will give much better results than trying to tune just on MGP. This is because a very small change in throttle results in a massive change in MAP on multi butterflies.
-
Hi can you post your full map or email it through.
-
You don't have to it can all be done remotely.
Have attached a PDF of what is involved.
-
From the photos you are in luck you have a matching set. The adapter is also a G1.
The switches are for two functions. The single switch is for setting the stepper motor step size. 1/2 or full steps. Normally set this to off.
The 4 way switch set the trigger edges from the CAS these are currently set in there correct positions so should not need changing.
-
This is a starting point
-
Coil normally has a +12 feed and we then ground the other side of it.
What you should have is a common supply across all 4 coils.
The Nissan ones will also have a common ground and then the third terminal will be connected to our or the factory igniter.
-
Not something I have come across before. Well as far as the battery type goes.
However different battery types certainly require different charging methods. Just have no idea what is required for a calcium based one.
-
Not very easily. Can you post a photo of the adapter just so we can confirm its generation.
-
Hi Glen are you referring to the printed manual or the online (pclink) one?
-
Hi Shoaib
Have you had success with this?
Haven't had a call so thinking you got it sorted?
Link V4 Misfire or Hickup in my tune
in Link G1

Hi Ron
Might need a little more to go on. Could be many things but something to try would be to try the other option under priority setting. ie if its on Cyl try Sync or visa versa
Failing that post up your map and we can have a look at that.
