that should help

 

Good post PSI, but it doesn't speak to the O2 sensor hook up., just everything else.

Silver - You will need an aftermarket Wideband if you plan on using the Automatic timer function on the Apexi TT (I assume this is the one you are reffering to since you are asking about the O2 sensor). I am ordering a wideband in the next week and plan on hooking up my Apexi TT to it, so i will post what I discover since I can't find directions on how to do it either...

If anyone else knows this process please post! It will save me a lot of trial and error, although it shouldn't be that difficult....

 

from what i remember, a wideband o2 sensor will not work. the issue with this tt isn't the reading of the o2 sensor, the stock one is perfectly fine for it to get what it needs. it's that the voltage that it's looking for is different from the one that we use, so it won't work. you would need to install a different o2 sensor that uses the voltage it's looking for (i think it's 0-5v).
