Z32 AFM Install

[gtrGhosTDoGG11]

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.

[gtrGhosTDoGG11]

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

If you change the AFM, the load points in the fuel map and ignition map will change won't they? If they do then it will need to be re-mapped.

Read the stuff on Pauls site. It will answer your questions.

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?

[PyroIndustries]

I'm still waiting for my PFC to arrive and have been told its better to have a z32 afm

if i was to wire it in on the stock ECU would it work or lean out?
