Maybe one of y'all have run into this, I'm ex-Parts Mgr of Grubbs Infiniti and was very involved with the F.I. Z's and G35's. One of my customers has a built 350z (Arias Pistons 9.5:1, Pauter Rods, Greddy Twin Turbo's, Return Fuel System, Wabro 255, RC750cc injectors, Unichip). When I try to tune the car I can't get it anywhere near it's potential, the AFM just isn't big enough for the fuel the car is pushing. My question has anyone tried an AFM from the late model Q45/FX45, or for that matter has anyone run into this problem or am I going in the wrong direction with this?
Thanks,
Mark

 

It may just be because it is late...but I can't think of anything off the top of my head that stands for AFM.

Enlighten me.

 

Air Flow Meter aka MAF.

Unless you get away from the blow-through style that the Greddy setup has then even the Q45 MAF isn't big enough for a built motor. MAP tuning is about it.(for the time being)

 

Ahh...i've seen mass air meter and mass air flow meter used...never AFM. Thanks.

Correct. There are a few people/companies working on a larger MAF.

 

I know with the Emanage Ultimate you can do a MAF change, but I don't have my laptop with the software on it with me. Just curious as to what the EU says you can change the MAF to if anyone has the software with them.

 

Thanks for the input guys, I'm feeling my age, old school AFM (Air Flow Meter), today MAF.
