i beleive that my AFM is crook as my fuel economy is progressively getting worse, and im thinking of replacing it.

if i was to replace it with a Z32 would i have to get my fuel ratios tuned with a DFA or the like? or would it just go straight on without any of the hassles?

i cant replace mine with a new one the same, as there arent any in the country, and i can get it repaired for about $300 but i will have to send it to melbourne and i'll be without it for 1-2 weeks. my standard (R34) AFM has a pink sticker.

i am not qualified to answer that exactly but it will probably run out of resolution just over 200awkw however that doesn't mean u need to upgrade, i think that depends on how linear the tuning response is above 5.1v.

SK no doubt should be able to answer the question acurately.

Stock AFM and injectors will be good for the magic 200awkw.

All the differnce in AFM's is resolution as highlighted above. I would personally just replace it with a stock one.

Have you just thought about cleaning your afm? Just get some contact cleaner and spray the filament...

well i bought the standard AFM from wolverine (cheers heaps for that Andrew) and ive fitted it to my stag.

i noticed straight away that the small amount of backfiring i used to have, has ceased, so hopefully it will answer my fuel economy crisis.

I went and filled up my tank at the servo and reset the trip odometer, so i'll let you guys know the outcome.

WOOHOO!!!

after replacing my AFM with the second hand one that i bought from wolverine, my fuel consumption has gone from 23L/100Kms to 14.3L/100Kms

the backfiring did come back, so a tune with the DFA will increase it even more. ill probably get it done once ive finished my exhaust

>_<:D:D:(:):D:D:D:D

Nice one EGA. I'm assembling my DFA and Controller this week.I'll see if I get better than usual 16. If not much better an AFM might be next.

P>S> I thought I had sent this before but it sank.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
