its in the FAQ - select VG30 AFM From the menu - the VG30 is the engine which uses the Z32 AFM

this will load the base ramp values for the Z32 - it still needs a full tune when you change AFM

if your car is relatively stock it will be fine if u drive it steady. I put my PFC in for a bit one day for a play and just ran around off boost at lower revs and it displayed next to no knock. The base map is pretty fuely i think but as long as u drive it to your tuner (if hes not a great distance away) really lightly it should be fine. If you have any doubts just run the stock ecu till u get there or nearby and change it then

It wont be driveable.

Yes it will!

I put a Z32 AFM in my R33 GTSt about four weeks ago, changed the PFC over to VG30 AFM, and have been driving it daily on the base PFC maps. Got a wideband Oxygen sensor and it holds around 12 when accelerating hardish, and around 14 when cruising...cruise is a bit rich for my liking...knock is always low though...

Other related mods are FMIC, 3" turbo back exhaust, pod filter, 10psi boost etc...

Going to put bigger injectors in soon, and then off for a tune... :D

Willing to put his motor on it?

It has been tuned for the current AFM, so it wont be running hell rich like a stock map which basically couldnt kill a motor if you tried...

Most likely the tune will be close to perfect, not rich and so on. Adding in a larger AFM could spell disaster.

I think its a silly risk when it is a 15min job to change at best, i would drive to the tuner, change the AFM when you get there, rest assured you will not mince anything.

      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

      M35 VQ25DET starter motor

      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.
