This one is probably best answered by the Apexi dealers - however based on my experience:

The PFC boost control kit uses the same boost solenoid as the AVC-R. The latter has some sexier capabilities such as gear based learning, scramble mode etc as well as having the ricey blue screen.

On my old S15, I had a PFC and an AVC-R. These worked independently ('tho in theory I guess you could run a parallel lead to the PFC to show boost on the H/C). For my current car - I picked up a cheap PFC and will probably use the boost control kit as I'm not particularly worried about the "Blue Screen" look and prefer functionality over looks. In the longer term I suspect an Autronic unit will find its way behind the kick pannel.

There is no need for an S-AFC with the PFC as there is no additional functionality offered by the S-AFC. Likewise with the S-ITC (ignition controller). It would look pretty ricey, however, having 3 blue screens mounted one above the other!

Hi JET-33, I agree with GAV, waste of time and money. Commander will show trace and peak hold, so if you can live without the pretty blue screen then don't bother.

Hi GAV, just gotta ask, why change from PFC to Autronic? I personally like Autronic ECU's we have used them in lots of our race cars. Other than data logging interface with a dash, I can't think of many reasons why an Autronic would be better than a PFC. Care to elaborate?

G'day Sydneykid

Actually I like the PFC, although they aren't really that popular with tuners in Perth (Lumpy excluded).

The reason that I will probably eventually go Autronic is mainly economics.

I expect to take my GTR (probably fairly soon) to the stage where I will max out the AFMs. When I change over terbs I will also want an EBC as well.

By the time you add 2 x Z32 AFMs and the boost control kit to the price of a 2nd hand PFC with H/C, you are getting near Autronic price.

Perth's summers played havoc with my S15 that was probably tuned too near the edge. With the PFC, it's not a simple matter of reverting to a more "conservative" hot weather map unless you go back to the default map, thereby losing your custom map created on the dyno.

I don't have the option of using a Datalogit as this is not (yet) available for the PFC Pro that I have.

    • 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  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
