Factory ones support ~280rwkw

2x Z32 would support over 400rwkw

You need aftermarket ECU to use anything other than factory however.

Plenty of more detailed info on the forums - have a search.

can u still run z32 wif factory ECU?

Come on ash, you know better than that, z32's can be used with a remapped factory ecu, but unless you have well over 400rwkw, there are better options

im tryin to find threads about it but cant, can u help me out please..

i wanna know why i cant run z32 wif a factory ecu

[R31Nismoid]

Why do you want to find threads?

I've told you quite clearly with a 100% factory ECU Z32 AFM's cannot be used as the factory ECU is not setup to support anything other than the factory ones.

It's as simple as that.

It's not factory if it's been modified in my book - you know better than that

Nistune USES a factory ECU, but it's not a factory offering as it's remapped/chipped/retuned etc.

Z32 are bigger.....

my 2 cents

[paulr33]

std GTR AFM is 65mm vs Z32 AFM which is 80mm

std nismo GTR AFM is 65mm but with higher resolution sensor (like Z32 in 65mm shell)

Z32 flows more, is larger and has higher resolution.

for BNR32/BCNR33/BNR34 depending on ECU options you have choice of

2 x RB25 AFMs

2 x Z32 AFMs

2 x Nismo AFMs

Nismo is usually preferred as everything mates up, ie its still 65mm

whereas if you use Z32 or RB25's its 80mm each so you have to change pipework etc

a pair of RB25 AFMs is probably cheapest option.

all of the listed options need a different ECU or a piggyback or a remap to make it work

and besides, why would use a STOCK ECU (no remap) and need to replace the AFM's

its kinda a conumdrum, ie you wouldnt be able to make enough power to max the stock AFMs' but retain factory ECU (without a remap) and no other piggyback or standalone

i wanna know why i cant run z32 wif a factory ecu

wif??? oh with...

To understand why you cant use a z32 Air Flow Meter WITH the factory tuned ecu, you will need several things:

-Basic understanding on how a modern engine managment system works

-Basic understanding of how a hotwire air flow meter works

-Basic understanding of the relationship between the two

My suggestion is to get some education on the subjects above. All the info you need is well covered with in these hallowed forum walls OR you can find plenty of BOOKS (those thick paper things) written on the subjects.

Cheers
