Unplug the safc, and resest your ecu?

and that narrowband that you have gives terrible readings, if that was reading rich or lean, it was probably inaccurate.

Before you even mess with an SAFC you should get a Wideband at the very minimum. Unplugging the SAFC will not reset the ECU, you need to reset the SAFC to the previous settings or just zeroing everything out. You may have added too much fuel and it bogs down because you are drowning the cylinders. Not knowing the mods to the car then touching the current tuning settings is asking to blow something apart. I recommend going back to the previous setting or at least finding out the injector size, what type of fuel pump, ect.

Well, i guess i should have been more clear. As you put it up there ^^

Ok i will rest the safc and zero everything out and see what happens. And i will contact dealer and see if he can give me the perivouse owners info. hopefully.

zeroed out everything and runs worse! #### im really kicking myself!!!!

What type of car is it? I've seen in some of your other threads that you say its a TSI. Also find out what type of injectors you have and I'll be able to give you general settings for the SAFC.

Check your MAF and the connection. Also how many Hz does the SAFC say you're flowing? Remember to make sure the SAFC settings say its a Karman sensor, 4 cylinders and the arrow is pointing towards the right. This thread I'm about to link you to will help you with settings and wiring check.

Yeah , the ECU doesn't really get reprogrammed by the SAFC, just tricked. If he did unplug the SAFC the settings would no longer apply but he also wouldn't get a MAF signal since its being re-routed through the SAFC by cutting the MAF wire and plugging it into the pink and orange ends of the SAFC harness.

the sensor type was set wrong se t to karmen and runs now!
