Just wondering if anyone has been able to run GTR injectors in a RB20 without running the dropping resistor???

Reason i ask is that there is a topic on NS.com at the moment with a bloke stating he is running GTR injectors in his RB20 and not running the resistor pack as he is using a PFC...

Now i'll be buggered if i can find anywhere in the PFC settings where i can change the impedance of the injectors within the menu's so i dont have to run the resistor pack nor can i find any other information (on SAU or the net) that clarifies it can/has been done :worship:

Can anyone else shed any light on this as im keen if it can be done and how as it would save many of us RB20 owners with a cheap injector mod as its the ballast resistor pack that is the hard thing to come by ;)

Cheers GMB

You dont have to run the resistor pack

BUT you DO have to run resistors inline to each injector

I realise you dont have to run the GTR ballast but it is required like you said, the person has stated that he is not running any resistors and that it has been changed within the PFC settings.

A resistor pack can be easily made for about $10

Which is what was done on my first 32 ;)

My question isn't about running a GTR ballast or making your own, its if you can get away with not running a resistor at all???

It is possible to start and run the GTR low imp injectors on the rb20 remaped ecu or RB20 pfc without a resistor pack.

BUT.... As rpms increase you most certianly stuff/overheat the injector drivers. Its a matter of WHEN not IF.

First you will smell a little electrical burning smell then the car will die and you will be left stranded with a stuffed extremely rare rb20 pfc. ;)

Got a link to this thread on ns.com; keen to check it out?

Which is exactly what i thought Cubes, i just thought i may of missed something though in my searching over the last 5 years ;)

Check here for link :worship:

The microtech's injector drivers are suitable for both high and low imp injectors without a dropping resistor.

The std ecu and powerfc does not.

The PFC is a glorified (knock display, increased load points, faster processor) real time remappable std ecu.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
