went for a hard run today through some twisties. afterwards, i noticed that the safc is not reading my throttle percentage (hence not compensating on hi-throttle setting). didnt notice this before and seemed to be working a few days ago. only thing i've done to my car was install a grounding kit. all wires to ecu seem fine and sensor settings (car type, etc) seem right on the money. anyone have any ideas???

side note: check engine light came on. are these issues related?

thanks!

 

My check engine light came on. I tried for 3 1/2 hours playing safcII. I unhooked it and the CEL wnet out and has not came back on.

 

what did you do on the SAFC to get rid of the cel, subman? mine is on too. it does'nt come on the first time after I reset the battery, but after that it lights up.

 

I just unplugged the SAFCII and it went out. I think you have to be a rocket scientist to program the thing right.

 

check all connections. Solder. Dunno what else you may be doing wrong.

 

had a loose vampire clip connecting he throttle wire from safc to ecu. put in new clips problem solved...

 

Sometimes if you get a steady SES light, you will need to unplug the battery for a couple minutes to clear it.

 

but will that solve it? i'm wondering b cuz my original o2 sensor is just hangin out there and not reading anything. i understand that there are other sensors, but is it ok for it to just be hangin out? the guy that helped me install it said the if the SES comes on, then I should put the o2 back in the housing in a new hole....
