i just bought a homemade kit for a y8 from a fellow ht member...and i put everything on and came across the o2 sensors...there is a bung for one o2 sensor on the DP...i was just wondering if i would be able to use the primary and only that o2 sensor...if i dont will i throw a cel...would i have to put an o2 sensor on after the DP for instance the cat?...any suggestions... i am lost and i cant find the seller to see how he set this part of the kit up -thanks

 

u need 1 on the down pipe(primary) secondary is not as important,excetp for emmisions. u will throw a cell if secondary is not there but it wont create problems.youll just have to be driven nuts staring at the eng light,lol

 

haha ok well you know what that means time to put pics on my cluster...haha jk i will find a spot thanks...

 

yes please do i want to see a pic of your eng light. i have my own eng light that i could stare at as soon as i put my test pipe back on.
