[RESOLVED] Pumpgas log of small 16g at 36 lbs/min . . . Questions about fake maf

[dsm-onster]

I plan on switching over to fake maf. I thought I'd get some insite on this log. My MAFSD oscillates up to about 2200Hz. . . Is this normal? I have my maf "switch over" set at 1000Hz. I see that the standard dsmlink VE table is about right for my set up even though I have a cam upgrade. . .

What's going on here?

i always had problems when i used the fakemaf function. The airflow signal would always get erratic.

I just went ahead and upgraded to a 2g maf after the problem because i remember tuning it was a pain. Sorry i cant be too much help, but thats how i solved my wierd symptoms with fakemaf!

So I'm not the only one that sees the graph get choppy. . .

Did your signal ever do like mine: clear up after a certain Hz level?

Why are you switching to fake maf?

Time to put in the 2g maf or Evo maf. Ig mafs suck 30lbs air limited!

But his profile says he's using a MAFT.

Yea he is running a maf-t, I dont see why you would want to run fake maf. DSMlink and the maf-t work great together.

Oops, I really need to update my profile again. I sold my maft to my brother (kind of. . . I still have it but not installed). The GM maf accumulated water during a water injection solenoid failure. . . .I know I could get another, but I like knowing my intake temps.

I was just wondering if I could push the stock maf. It doesn't seem too choppy even over 2000Hz. That seams to be well over the 30Lb/min threshold...

Received an update from Thomas of ECMtuning. It definately was the "fake maf" bug.
