I have just got myself a Z32 AFM and was wondering if I plug it in and replace it with the standard one in a R33 will it stuff up the power fc tune and run lean or anything?

Do I need to tell the FC its an Z32 AFM? What happens if you dont?

Does it need a retune?

Will it cause any damage?

The stock AFM was not maxing out, but rather would just go the tuner and get the Z32 tuned together with injectors etc.

The problem is that iam trading in the stock AFM hence need to run off the Z32 for a few weeks.

Thanks.

ok, the Z32 will not just plug in. you will need to wire it up. you can select the VG30 AFM option in the PFC this will help it to run, but in my experience it will still need a tune and probably wont run very well until this is done.

Beer Baron is correct. I've also just bought one recently and was told by my mechanic that my PFC will need to be retuned once it is fitted. I'm sorta in the same position as gtrGhosTDoGG11, I've also got injectors and new fuel pump on the way, so I'm just going to get them all fitted at the same time as the AFM and then do the tune.

if it was my car i wouldnt expect a powerfc retune would be required.

you simply select the vg30 afm in the setting, airflow menu and that should be it.

the powerfc will recalcuate airflow vs voltage and go based off that

id be pretty surprised if u had to retune as well as choose the new vg30 setting

correct me if im wrong cos id like to know, but just amazed if it needed retune

I'm pretty damn sure that you are right.

Just plug it in and select Z32 from the AFM list, and thats it. The powerfc re calculates it.

Thats what I assumed. But had to make sure, cause I didnt want to stuff anything up.

Iam not adjusting boost or anything, its just by upgrading the AFM i can handle more air coming in, but since the air coming in hasnt changed, why need to retune?

Maybe the diamter is different? Hence air volume coming in might be different? Hence yous elect the Z32 from the list hence this should recalulate it since it knows the different diamter? etc?

Those are my thoughts.

Is there a step by step guide to get into that menu and changing to Z32. Its in JAP i remember when you go in there.

Lets start at the main menu and tell me the exact seqenece of keys to press. =p

in my experience a re-tune has always been required. yes it will run once you plug it in and select VG30, but it won't be all that crash hot.

have you actually fitted a Z32AFM? if so what was your experience? I have seen GTSTs, silvias, GTI-Rs all needed some re-tuning after fitting the Z32 AFM.

the diameter is the same mate, it's the sensor which is different. electrically speaking.

my advice is to take it to someone who knows what they are doing.

and BTW it's not in jap, it's in english.

Sorry to be abit of a hi-jacker to this thread, but my current set up with stock turbo and the car pushing 202rwkw, I still have the current series 2 afm in my R33.

On the PFC, im not too sure if the AFM ismaxing out, but my reading is 5115 on the AFM voltage all the time after a quick sprints.

Does this mean the AFM needs to be upgraded to say a Z32 on my car?

Will the Z32 afm provide any benefit in terms of economy or power delivery?

      Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.

      J50 clock date suddenly reset to January 1

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
