tuning AEM wideband
 

i have a s4 T2 and i have a safc2 and a AEM wide band gauge...when the car was sitting at idle i was trying to lean out the mixture and it seems as if it goes richer on the gauge when i lean it out on the safc...could something be reversed or something??

Yes. Go back to the settings for the SAFC and see if they still show 4CYL and the arrow UP and TO THE RIGHT. And that is is FLAP.

yep thats what was wrong i went into the settings and everything was mixed up i dunno how that happend.....oh well i think the car should run alot better now...thanx alot for the help!!!

damnit i had to replace the turbo to manifold gasket and i had the turbo off when i was messing with the safc and i couldnt start it so i guess i shouldnt have assumed that that was the problem cause i started the car and its still doin the same thing....any other ideas???

could it be the wireing to the ecu?

did you ever find out what was wrong?
