#20955, "S-AFC sensor problem?"


          


I'm having airflow reading probs.
I have my sensor at pressure aT 7-7
I leave the hot and flap at 1-1 and keep hot highlighted and exit and get 4% airflow at idle.
But when I zero hot and flap I get around 30+% at idle.
I'll highlight pressure at any time and get 0% readings.
When I have my S-AFC my car seems to hesitate going into boost only.
It also throws a code.
I've had it hooked up for about 5 months now and this just started to happen.
Anyone experienced any of these problems?
Please let me know whats up here.

The way it is supposed to be..

>I leave the hot and flap at 1-1 and keep hot highlighted and
>exit and get 4% airflow at idle.

The airflow parameter is not applicable to our cars. Set it to pressure.

>But when I zero hot and flap I get around 30+% at idle.

See above.

>I'll highlight pressure at any time and get 0% readings.

Because you're looking at airflow. Those wires aren't even used in an AFC installation on our cars. Set the Monitor to display pressure, not airflow.

>When I have my S-AFC my car seems to hesitate going into
>boost only.
>It also throws a code.

Because it is looking on the wrong wires for the signal. Set it to pressure.

>I've had it hooked up for about 5 months now and this just
>started to happen.

I see -400+ mm hg @ idle
I have flap and hot at 0 in 0 out
pressure at 7 in and 7 out
pressure highlighted and exit.
still between hesitates in boost only.
Feels like almost a fuel cutoff.
When I disconnect the safc to the map sensor it runs perfect no hesitation or fuel cutoff feel.
When in boost I see pressure readings go to -4 mm hg going into boost.
In wot it feels fine to.
What kit are you running?
I'm thinking of disconnec the black box that I got from HRC to the map sensor and just use the safc to adjust fuel curve.
What do you think?
