AFM adjustment

[hertygerty]

Sorry fellows I know this has been around a few times but but forgot to write down I my book of knowledge. Could someone please tell me the impedance and adjustment proceedure of the AFM

[VL Berlina 5speed]

there is a little cylinder on the side off the Afm
pop the lid of the cylinder thing and there should be a screw in there,
get a philps head scredriver and turn the screw to adjust the sensor,

think right for more richer and left for leaner (if not other way round)


this pic is where the screw is located in

O and there is a way to test the Ohms its producing, get a circet tester and set it to ohms touch the 2 prons to the to little legs on inside of the AFM, the reading should be 382ohms (factory) if its not change it till you get that reading by simpaly turning the screw as discribed b4
and the engine has to be running while doing this
(not postive this is the way, some 1 plz confirm it 4 me)

[prizedbnx]

well its probably reassuring you saying all that then having doubts

[VL Berlina 5speed]

im 95 % sure justn not positve on the multi tester points eg wat touches which 1

[harry3]

the AFM cant work properly if there are any leaks between it and the engine in the air intake pipe, such as a split in a rubber section or a loose clamp

[NORTI]

touch multimeter to points 1 & 6. turn screw til reads whatever you need to suit whatever your running, ie factory or advanced.

By the way I had to use a flat screwy ya know cus of the flat headed screw thats in there... hehehehehe

Thanks fellows problem 98% fixed AFM was at 512 ohms I reset it to factory setting making car run less rich ,it still has a little flat spot when you first start to drive.

[Stewart1000]

you wanna make it run a little rich if you have those odd moments when you liek to get off fast

When you say pins 1 and 6 do you mean the pins where the plug connects or somewhere inside the intake?

I measured mine on the plug pins there and got zero ohms between 1 and 6??

Leave it pluged in and slide the rubber cover back, then you can get to the pins..ok

[hobnog]

Pulled back the plug and ran car to test.

Zero ohms between terminal 1 and 6.

Does this mean my AFM is rooted??

[SMOKN_LJ]

Being at zero ohms doesnt mean its stuffed just adjust it untill it gets to 381 ohms, the lower the ohms the richer it will run so the higher the ohms the leaner it will run. When i checked mine it was on 760 ohms.

[DVS87]

so how many ohms do u boys and girls have???

[VLACS]

how the hell do you get that little blue nobbie off the screw part. its seems well stuck in there

[DVS87]

effort i used a real small flat head and shoved it in and pried it out

[VLACS]

yep
that wont work on mine. its well and trully fkn stuck. how are they stuck in. if there screwed in il be pissed. glue? any one

sorry mine was gone when I got the car, but I'd say glued as joe average wasn't ment to turn the screw!!

[DVS87]

yeh im thinkin glue. maybey someone before super glued it or somethin just to play with your head??!!??

[DVS87]

lol, not if u close your eyes and dont read this thread

[VLACS]

right so theyl give me a warning and ill say why cos i got my eyes close. then ill back up onto his roof with a milo tin still with sticker attached and do burn outs on his roof with my 600 decibel exhaust going....

so ill delete it then

k guys.. im bringing this post back from the dead..
im trying to adjust the afm, n ur meant to do it while the car is running, when i unplug, the car dies.. how do i keep it plugged in and have the 2 points from the multimeter in there?

[tougHnA]

pull the cover thing of the plug to expose wires the place the prons 1-6 while car on u should get a reading of 3.66 ohms is aftermarket afm spec.

[My Car Pwns]

k i got to it and its reading -1194
if i turn the screw it goes worse (-1200+)
but if i turn it the other way it wont go past -1102
reckon my afm is stuffed?

[My Car Pwns]

anyone? i got a date tonight and i dont wanna borrow my moms car.. lol
