My car is originally OBD2 but i used a chipped P28 and harness to convert them to OBD1...since my car has 2 O2 bung on them(before cat and after cat)...can i move my primary cat to the secondary location and mount my AEM UEGO O2 sensor on the primary cat location? Or is there any rule on how far should i put this Uego O2 away from the exhaust? where would be the best place to mount this to get the most accurate reading possible...

thanks much
