Sorry for no before/after dynos or anything but I'm successfully running the Q45 MAF with my hybrid 3.5 swapped 98. I searched and only found one other mention of someone running this MAF but no real info. Below is how I went about adapting it to my setup.

Wiring is it in is a joke.

A32
Red - +12v
White - Signal
Black - Ground

Q45
Black w/ White stripe - +12v (could also be black with red stripe)
White - Signal
Black - Ground

A lightning MAF adapter will work if you re-drill it. It's a little larger than the MAF opening but a 3.5" coupler will still stretch over it.




I used this for the IACV port.
It's for silicone couplers no larger than 3" but you can easily bend it out a little for a 3.5" coupler.

I'm still waiting for my velocity stack. So I just took the filter off my other car and shoved it into the MAF adapter for now.

The bay is 100% beater status but here it is installed:


I'm using 01 in 04 out on my VAFCII and I increased my fuel pressure to 70 psi. I still have a lot of messing around to do but the VAFCII only making corrections 1000rpm and up is the reason for the crazy high fuel pressure.

The midrange feels healthier but I haven't really pushed it due to lack of tuning.

 

What afpr are you using?

 

It's an Aeromotive.

 

Nice, you beat me to it!

 

cool man...

 

Good stuff!

 

Its funny you post this now since I started to take one off of an M45 I found at the junkyard but decided not to. iFail

 

The a33b is:
yellow/green
red/green
black
white

Anyone know how i can wire the Q45 MAF up to this?

nicely done man,i also have a Q45 MAF but i havent done any before and after dynos ,but i felt it pulls a little more in the top end(maybe my Z33 IM with 5/8 spacer helps too)
i have a VAFC2 and DE-K injectors and i had to had something like 8-9% almost everywhere,i ant to get all the parts to do a returnless fuel sistem and then i will tune it to perfection

 

I SSIM'd the intake a few days before I installed the MAF to get an idea of what each mod would do. The Q45 MAF definitely compliments the SSIM.

I wasn't expecting a noticable midrange increase from just the MAF but the power just comes on sooner and smoother than before. The top end obviously pulls harder too.

 

Why not get a LRMAF housing instead?

 

yes and i felt the engine more responsive, but a dyno would be nice,just ti see what it does on a 4.5 maxima
