[Tach Needle sweep issue.]

Found the problem .... the ECU is seeing 14500+rpm on startup so is cutting fuel and ignition. So I am now searching for the wiring issue, will most likely replace the whole EFI Harness.

Oh, and the Tach needle is still doing it's thing.

Hi Simon,

Thanks for the response.

ECU = G4 Plugin into a 1992 300zx ... engine = Twin Turbo

Fault has developed ... Have fitted new Cams and discovered issue upon trying to start the car for 1st time.

ECU is giving the following faults:

AN6 at 5V

AN V6 at GND

AN V3 at GND

AN T2 at V5

The tach needle sweeps all the way around to the stopper pin then comes back to 2000rpm and won't go lower even with key off.

The car will fire but won't run -  are the 2 related ?

[2nd Fuel Pump]

Hi,

I have installed a 2nd Fuel pump.

Can I set it to come on after say, 2000rmp ? if so how ?

Or, am I better to just have both pump run at the same time ?

Cheers

[Object has no name]

Hi,

I am getting a 'object has no name' error when trying to connect to the ECU,

The car still runs fine, just can't connect... I am wanting to install a larger MAP sensor.

What's happened??

[5 volt supply]

I want to have the ECU read fuel pressure, can I use the same 5 volt supply for the Fuel Pressure Sensor which is used with the Air Temp. Sensor ?

Which 'an volt' is the interal MAP Sensor connected to. ?

Was using a external sensor connected to 'an voly #4' ... the ecu seems to be looking for this and won't use the internal one

Hope this makes sence to someone.

Sorted.

[MAP Sensor]

Does the Plug n Play Nissan R32 GTR Link G4 have a onboard MAP Sensor?

[Auto Tune]

How effective is this feature?

[ECU "knock" recording]

I have "knock" sensitivity set to "150" ... the ECU is recording "knock" events of "100" is this ok, or do I have a Detonation issue?

[300ZLink]

There is adjustment for the activation of the VTC (cam timing) at lower rpms but doesn't appear to be any way of adjusting the release point at higher rpms. Does this mean that the oem release point is being used?
