20955, S-AFC sensor problem? Posted by dsm2g, Apr-30-02 06:06 AM
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..

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 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?
