[G4+ plug in - 300Z questions]

So got this fired up on the weekend, which was great. I have a couple of questions now. The attached trigger scope, normal looking? Seems pretty uniform, just the little variations at top and bottom of some that I am asking about. If not normal, possible causes? I have not tried adjusting the crank sensor placement and/orientation yet. Using a Cherry Hall sensor, and modified Cas for sync. I have circled some of the bits I am asking about in the screenshot.

Next question is around fuel pumps again. I have Inj7 set as function 'Fuel Pump' and wired to trigger OEM FP Relay, whose output in turn triggers 2 relays (one for each pump) that give battery power to both in tank lift pump and external large fuelab pump. I have Aux 2 wired to the speed control input on the big external pump.

I am seeking clarification on the fuel pump control settings, and which settings relate to which outputs.

Is Inj7 prime, then on where engine speed > 0, and all the other options there relate to Aux 2 only?

[GP Output Question]

The 3rd condition, you select DI as 'on', and then the next selection is the DI 'number', in this case (Jay's example), 1.

Oh well, thanks for the reply

[Setup Analog to Can Converter]

Just did a search for SSI-4 and found this thread.

 

I have an Innovate SSI-4 that I purchased to use with the Adaptronic ECU I had previously. Never used it, not really worth my time/loss to sell it.

Can it be put to any use whatsoever with the G4+ plug in I have?

[G4+ plug in - 300Z questions]

Cool thanks mate. All this is purely theory for me at the moment. Have not yet connected the ECU to the car.

[G4+ plug in - 300Z questions]

So I have another question about the flex sensor. I have read the info about wiring it in to a DI (1-8) etc. So I was looking at what is spare in the 300z basemap. Turned on DI5 and allocated ethanol sensor. Then I happened to notice the 'Ethanol Sensor' listed at the bottom of the DI list. Is this some kind of preconfigured input? If so, where do I wire my sensor if not (one of) DI5 to DI8 on the expansion looms?

[G4+ plug in - 300Z questions]

Thanks again for all the info Adam. Screens attached of help and software menus regarding FP cont etc. Assume they have just been mixed up somewhere along the line?

Is it possible to know if there are any conditions etc applicable to any of these 4 being active? Only asking as the factory pump control does the prime etc.

 

[G4+ plug in - 300Z questions]

Hi all,

I am in the process of mapping out what I need to wire in to where for my application (Z32 with plug in g4+). While I do have 2 XS looms which should be enough for me, I am also trying to establish what factory pinouts are used, which ones are not used, and which ones are configurable.

I have aligned the info in the link manual (and the descriptions provided in the software for the 300z basemap) with the factory pin functions, but there are some gaps I think. I have attached the lot, but mainly interested in these: EGR, AIV, FICD, PRVR. The ones below are not mentioned (and aren't plainly obvious like grounds/powers etc).

PIN	Link Manual/Help	Desc from Link Basemap/Software or Nissan Data
47		Check Signal on Diagnostic
22		Diagnostics Send Data
21		Diagnostics Receive Data
8		AIV control solenoid valve
5		Signal to Automatic Transmission
102		EGR
56		Signal to Automatic Transmission
54		Throttle Valve Switch (idle position)
40		Signal to Automatic Transmission
37		AFM Orange Wire (Not Used)
33		F.I.C.D. Solenoid Valve (fast Idle control)
31		Diagnostic Clock
16		ECCS Relay Coil Ground
15		Signal to Automatic Transmission
14		Signal to Automatic Transmission
115		Oxygen Sensor Heater
111		PRVR

 What does the ecu do with these? Can I get control of them?

 

Next, Aux - Inj 8 is tagged against 2 ECU PIN's, 19 and 6. Nissan says that 19 is the Rad Fan Relay and 6 is Rad Fan Sub Relay. Assume I have removed my fan and would like to use this driver for something else, which pin would I use?

 

Next, I am interested in the fuel pump controls.

PIN	Link Manual/Help	Desc from Link Basemap/Software or Nissan Data	???
4	Aux - Inj 7	Fuel Pump	Nissan says this is AAC valve
104	Aux 2	FP Control 1
35	Aux 5	FP Control 2	Nissan says FPCU
18	Aux 6	ISC Solenoid	Nissan says Fuel Pump Relay

 

Interestingly, Nissan says that PIN 4 is the AAC Valve? FPCU, PIN 18 is the fuel pump relay (Link says ISC Solenoid???) Have these been mixed up somewhere?

PIN 35 and PIN 104 are for the FPCU.

With my fuel setup, I have the FPCU replaced with a relay (still triggered by ECU) to control the in tank pump (full time full speed). I have my big external powered with direct battery power via a relay off the same signal as the in tank, but the pump has another speed control by PWM. I assume I can use either PIN 35 or 104 for this? Looking at some kind of PWM by injector duty relationship.

 

Finally, silly question (if the others weren’t also). What is the function difference between a temp input and a volt input?

I had to source a donor ecu to use for the case. Luckily a mate recently sold his GTR as a shell so I got his Mine's ecu cheap enough to bin its guts. Only last night installed the link and XS looms.

Ross balancer and Cherry sensor are installed. I pretty much just have to finish the wiring for all the other inputs and then hopefully try and fire it up (or at least be able to crank it and check the triggers).

[FP Regulator/Pressure]

Not being able to adjust pressure down lower than 3 bar isnt ideal, I can drop mine to nearly nothing. But factory askes for 3bar without manifold reference, so it is on spec.

Can has previously made 616hp @‌24psi on pump fuel. This was pre fuel system upgrade with Nistune. Car has gone 11.3 @‌ 120something, when it had about 500rwhp.

 

Current work in progress is setting up the crank trigger system. I have the crank sensor mounted, and I have just modified the CAS for the cam pickup last night (aluminium tape over the optical slots). Still haven't decided exactly how to attack the cam sync, but figured this is a good, cheap start.

 

I had previously got all the wiring in order for an adaptronic ECU, but since sold that (never used) in favour of the link. So I have to have another look at all the wiring for all the extra sensors again. Also have a fancy Specialty Z sump to go in at some stage when I could be assed.

 

Then it should be nearly ready for start up again.
