Z32 Afm And Pfc Question

Ok guys I have a couple of questions that I was hoping someone may be able to help me out with. Firstly I currently have a PFC, EBC, and Z32 AFM waiting to be fitted to my R33. Only other mods are 3in turbo back exhaust and a FMIC. I have plans to upgrade to GT-RS turbo early next year (also injectors etc.). My question is would it be worthwile fitting the Z32 AFM at the same time as I get The PFC and EBC fitted/tuned (now), or would I be better of waiting and getting it done at the same time as the turbo upgrade (next year)? Basically what I really want to know is will the Z32 AFM give me any sort of additional power gain when installed with my current mods?

I was also wondering is it alright just to use the PFC hand controller as a boost gauge? As I currrently only have the stocke boost gauge. Or is there an advantage in installing a conventional boost guage? Like as a back up or whatever.

Sorry guys im a bit of a novice when it comes to this stuff, thanks in advance!

z32 afm wont give any power increase....but it gives the ecu more scope for airflow with using bigger turbos and more boost and more fuel. It will only be useful when you go for the larger turbo, but regardless with the powerfc it wont hurt to put it on now...its one less thing to do later on.

Boost gauge doesnt matter...i know heaps of people who just use the commander to monitor all the engine stats including boost. There is no special thing to do, just do whatever your comfortable with and suits your taste.

PFC would only show boost if you get the otpional Map sensor for it ..

Z32 i would install now as you cant just plug them in and select Z32 and the tune be same as before... you will need to shift the load map to match the Z32 .. which is usually back to the tuners.. so save any mucking around and going back to the tuner and get it installed originally..

Personally i would say it doesnt matter when you do it.

Now or later wont really matter.

You are gonna have to get a full re-tune with Turbo/Injectors anyway.

I would do the Z32 then, rather than now as you stand nothing to gain by going it now.

Just personal preference, and its been a while since i disagreed with Chris :)

nah that makes sense t oo Ash :) hehe i just am going through the hassles of having to swap mine over for new inlet piping etc with the change to a Q45 AFM and now need a retune...

so i learnt that i should have got it all out of the way in the first tune :)

so realistically, i would wait til i had the turbo and injectors and save that $300 tune .. thats 1/3 of your injectors that you wont get back :)

      Got this r31 silhouette flood car to rebuild.

      So we have most the interior back in, and for the first time with one OEM speaker hooked up. The 31 is running, driving and now tunes!!! Hahaha yet another step for the sub that sat 10m under for two weeks!!! unbelievable really 👌 lots of love work and not giving up on her. Seen so many youngsters part way less, and in way better condition. I’m stubborn, thinking another problem is just a hurdle to overcome, One at a time. IMG_9277.mov

      That is correct. I'm using a modified ABS ring and a ZF speed sensor on my rear diff for speed input. I'm running a Haltech ecu.

      Been busy with the newborn. We originally thought we were going to go for a third, but we're good with two lol. He's starting to actually sleep now so I've had some energy to work on the car. It's been parked away in the garage since late November due to winter.  I went ahead and redid all my head oil drains. I originally had my front and rear head drain going into the same pipe but have since split them up. I also added an Ethanol content sensor to get ready to run E85 this summer. Tossed it on my return line. Sensor sits nicely under my intake manifold.    I also have a lot of parts that came in for my rear end. I'll be swapping over to a 3.3 final drive and doing the GK teck anti squat mod. While the rear subframe is off, I'll also change every bushing. We're planning on buying another house soon with the condition that I get at a minimum a 2 door garage, so I'll wait to have more room for this. Now onto the strange things that recently happened... After changing the lower rad hose (It had been sitting in my cabinet for well over a year and was the last hose I had to replace), I let the car idle in the garage to bleed my coolant. After running for a few minutes, it started missing. Got much worst within a minute or two and then stalled and would not restart. My crank sensor decided to crap itself. No damage, no explanation, just died. I went ahead and replaced it with another ZF sensor but the heavier duty stainless model with a shield. Tossed that in and started right up. Has anyone else seen this? I hate when things fail without cause. Luckily this was a blessing in disguise... This lead me to recheck my timing. It seems I may have had a beer or two the last time I had set my TDC angle as I was off exactly 5 degrees... I miscounted a line haha. I was running 5 degrees less then commanded. It's a little embarrassing but helps explain why my dyno operator seemed to think I should be making more then 478rwkws.

      Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!
