Remove Afm?

[SKY 34]

hi...I've heard of ppl not using afm in their cars at all...what is the advantage and disadvantage to that?

how does the comp read the amount of air entering then?

is it more to legality issues? I heard it's illegal for car to have no afm here in W.A?

You need to change the type of ECU in your car if you want to get rid of AFM's eg: Pfc or Microtech etc that use a MAP sensor to guage the amount of air the engine is using.Cant just take them out.

I intend to use Z32afm but i's out of stock..I got no option but to take them out...what's a MAP sensor?

[Lippo]

MAP sensors measure engine load by measuring how much vacuum the engine is producing where AFM's measure how much air is flowing into the engine

MAP stands for Manifold Air Pressure and the senor reads pos and neg pressures the ecu then adjusts the settings to accomodate.

MAF stands for Manifold Air Flow and uses the air flow meter.

You need one or the other.

i have a link ecu in my S1 R33 with a map sensor, works fine far as i know.

I do know that when i got defected...i didnt have an AFM and as the car came with one stock, i needed one to get my engineers cert for pod filter. i had to go and get a AFM so that they could take a picture showing I had one installed...( which was borrowed from a work shop off a VL and fake wireing lol)

altho they do the same thing, they think/"say" it changes the emmisions output of your car from stock...

i was under the impression that

MAF sensor was a mass air flow sensor

MAP sensor was manifold absoloute pressure sensor

AFM was air flow metre

IMO AFMs are evil i hate em and will never use one if i can help it

im running a microtec ECU which uses a MAP sensor setup instead of the AFM

other ECUs which use MAP sensors are

Haltech

Autronic

Motec

Link

Wolf 3D(i think)

Apexi Power FC (DeJetro version)

as for the defect issue

like ive always said if ur worried about being defected dont modify your car at all

nop...I have no problem with legalities..I dind't know abt MAP thingy...so I'm always wondering why ppl spend so much money to get Z32 afm when they can remove the whole thingy....I thought it's because they want their car to be legal..

nyways...does normal pfc has MAP?

waht advantage does MAP gives over AFM? why so eager to remove afm?

People arent eager to remove the AFM at all.
