I used the SAFC and got some airflow readings. I think they are to LOW. I want to know if you have a LB/CFM or SAFC airflow% reading for 2/3/4 Gears. Any or all.


Thanks

 

I see 4.6v at 14psi

86% injector duty cycle with 516cc

 

I think bags is talking about the % airflow. they are two different calculations because of the different circumference.

then the airflow would read "lower" because of the z32's larger size

 

Yeah, I don't see a voltage, I see 2 different airflow readings.

And Slimer, I saw 2 different readings with the Z32 Maf. That's why I ask

 

i read your other thread. good info.

I just think that it might be reading lower because of the size of the maf.

does anyone have the measurements?

 

Yeah, but with the Z maf, last week @ 8 psi I swore I saw 70% airflow on the SAFC.

And then now @10 psi, I see 50%.

I may have been outta my mind trying to watch the road and watch the SAFC.

That's why I am curious what readings others have seen. And I have a ODBII scanner that shows LB/hr. SO of you have that, That will help as well.

 

The Z32 maf housing is the same internal diameter as the A32 maf housing.

I have seen as high as 4.39V (datalogger), 67% airflow (SAFC). That was boosting at about 12 psi.

50% seems a tad low for 10 psi.

 

Thanks for the info.

Yeah I think so as well. I may have fouled out a plug. I am checking them and compression tomorrow. If I fouled a plug I have to go back to the dyno to check a/f.. darn it

 

ok.. i feel better now.. I am seeing 4.1xxV @ 10 psi

 

is that after checking the plug or was it a fluke?

 

The 70% I think was a fluke, I think I was dreaming or something. This came from a 2nd gear pull today through the SAFC.
