Reading Airflow Meter On Safc.

[SECURITY]

on my safc ive got an airflow meter. it reads in %.

does anyone know what it means and how its read?

[paulr33]

Airflow (Hotwire/Flap) usage ratio

If you go to the sensor check screeen you can get a voltage read out.

I don't trust the % read out at all.

whats it mean? what is it a reading of is what im asking.

[paulr33]

the airflow meter maximum amount of airflow it can show the ecu.

0% is no airflow currently going through and 100% is the maximum amount of airflow the meter can show to the ECU. its a 0.00v to 5.00v scale, with 5.10v being the absolute max

[justin911]

how does the safc no 5.10v is the max though ??

or is like 5.10v a generic standard or something ?

Fancy that i just discovered that lastnight on me SAFC aswell. Interesting little tool there.

Flat to the floor, 6000rpm was reading about 75% - got pleanty more mods to go till i would need to bother with a larger AFM.

if you are maxing out the stock afm and want to upgrade perhaps its about time you consider a stand alone engine management ecu instead of piggybacking on the stocker. theres a world of great tunability locked into a stand alone ecu that you can't achieve with the safc.

400 load points to tune

I've tuned around 90 of mine and the car feels fantastic and is good on fuel economy too

^ Damn you PowerFC people, i shoulda bought one instead of the SAFC2

Nah for the moment it should be sweet, does its job fine. I cant really justify spending so much more when i know im gonna be using the stock turbo for a while.

[paulr33]

im on the stock turbo still

[RedDrifter]

SAFC is good for a basic modded car but not so good for masive mods etc but I have seen a an safc series 1 running larger injectors for a bigger turbo on a VR4 Galant and it didn't do a too bad of job. Got it into the 12's.

So it can be ok but a stand alone power fc is by far a better chioce.

On the SR20 I could only get to about 75% on the stock AFM using the SAFC so you'd think you wouldnt have to upgrade. But the thing is so bloody small (50mm) that an upgrade is warranted anyway.
