Extra pin use for g4x 350

[WAC performance]

Here comes another newbie question. When it says "using unused injector or coil pins" does that mean I have to look at factory harness and look for that pin, then use it for the an volt that I need for? (temp/pressure sensor) Also, there's a fuel tank temp sensor I guess in my g35 but I have a temp sensor on the rail, (temp/pressure) can I use that pin if needed? One more question. When my key is in the first position, my o2 sensor gauge comes on. Does that mean the sensor itself is on and heating up? Thanks in advance and sorry for the newbie questions, just trying to learn this stuff.

To add context to your question, where does this quote come from?  You cant use an output as an input?  If you want spare inputs in the engine bay then there is AN Volt 3 in the MAF plug or AN Volt 10 & 11 in the O2 sensor plugs.

Pin 107 is marked as fuel tank temp sensor, AN Temp 3 in the ECU software.  I would expect it is in the fuel tank rather than the fuel rail, but you will have to either beep it out yourself to confirm or find a factory wiring diagram.

I would assume most wideband gauges have a single source that powers both the display and sensor so I would say most likely yes, but Link dont make or sell an O2 sensor gauge so you really need to check the documentation for whatever device you have.

Sorry. I've already ran the temp/pressure sensor wires into the interior and I have an expansion loom from ecu, I'm already using temp 4 on the loom but need an volt for pressure part no? Sorry I probably sound like a tool. I have a tuning session coming up and was trying to have everything ready for the tuner. And it's an INNOVATE wideband with controller. Wich is another an volt in I need no? That's why I figured I can use the extra injector or coil pins on ecu.

You will need an AN Volt input for the press sensor and another for the wideband.  If you already have both wires ran to the ecu then I would connect to AN Volt 10 on pin 35 and AN Volt 11 on pin 16

That's what I was looking for. Just didn't know how to word it. Sorry man I'm slower the molasses. I truly appreciate the time you take to reply.

I'm looking at my harness and I see 16 but 35 underneath it is empty. I'm looking at my fsm and it shows them both as AF sensor bank 1

Actually I just figured it out. The pins on the harness were different but figured it out. 16 and 35 were on the bottom of my connector. The colors you told me were correct and both sensors are working now. I think im getting the hang of it lol. Any advice for steps in trying to tune it somewhat myself, I'd like to drive it to the tuners instead of trailering it. The car starts, but runs like shit. Realizing I've put bunch of upgrades (1300x injectors, return fuel system, turbo, fully built engine and so on) anyway any advice on where to start would be huge, like the steps to getting it starting better and to idle normal.  I dont expect a full lesson lol, maybe the steps to learn. thanks on my part. Seriously appreciate the advice you guys offer.  Awesome group and product.

Have you adjusted the master fuel?

[WAC performance]

I got ID 1300 injectors but set on traditional mode. I've put all the injector info in and set up the fuel pressure and it's reading same on the radium gauge on the regulator as far as accuracy. The master fuel is 5 ms. Min effective pulse with is .05 ms. I'm just watching your video on how to send a file link. Once I figure it out I'll send a file. Maybe someone can look at it for me. Thanks for the fast response brother, and on a Sunday too. Appreciate it.

So does adjusting the master fuel not make it run any better?

It does somewhat but wants to stall. Or if I rev it a bit and let off of the gas, it dips down to almost a stall. I was thinking now that I have all sensors hooked up I can us quick tune. Or modelled mode.
