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?

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?

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
