Air Flow Meter Upgrade

[EGA41T]

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.

if you go Z32 you will have to get your DFA re-tuned

[EGA41T]

what would it do to the A/F Ratios if i was to drive before it gets tuned?

and how much does it cost to get the DFA Tuned?

U can use either a Jaycar DFA or a Apexi SAF-C2. I am waitng 4 my Apexi 2 turn up that I scored on ebay 4 $260.00 here, around $390.00 new.

EGA i have a standard afm sitting here if you want a cheaper option.

[EGA41T]

how much power can the standard AFM handle (4wkw)

[wolverine]

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.

[EGA41T]

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

[wolverine]

i'll take 10% of your fuel savings on a recurring basis and i'll slip you your bills back if you want?!?!

[EGA41T]

lol, you would be making money in a matter of weeks!

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.
