How much work does it take to install an af gauge say innovative and does it make a cel light come on?

 

it fairly easy you have to weld in a o2 bung unless your running a stand alone and have no need for your stock o2 sensors. if you just adding one in you

wiring is like wiring in any item power, ground, and maybe signal

 

were should you weld the new o2 bung in on. should i weld it on the my test pipe or to the header?

 

test pipe.

 

the test pipe can be easily removed and taken to a welding shop and you can mount it (the bung) completely vertical but for a header you have to take the car in and they have to some how drill it and weld it.

 

will the af gauge come with the bung or will they have to fab one up??

 

whats better innovate or aem

 

are you running a wide band or just narrow band off the oem sesnsor?

if you are running the signal off the oem o2 secondary then don't, it's going to be a flashing light show with hi/low reading only.
