Just to come back to this and to ask another question.
I decided to go a single wideband LC-2 sensor and controller with a dash display.
Until I get my 4.6 all sorted I will stay with the 3.5 manifolds and exhaust then upgrade to RR P38 manifolds and large exhaust.
With the current exhaust the pipes from each bank do not come together until near the rear of the vehicle just in front of the muffler. So I have mounted the bung and wideband there where it will sense gasses from both banks - the cables are long enough to reach the cabin area where the ECU will be etc. But that will all be temporary.
With the new exhaust I want to go a twin system with one exhaust from each bank with just a balance pipe joining them.
So my question is - if I put the O2 sensor bung in the balance pipe and not either of the main exhaust pipes will that be OK? Will I still get valid input or will the gasses in the balance pipe tend to just sit there and not move?
If that is not a good idea, I will weld a bung in each exhaust pipe and run the O2 sensor from one of them so when driving will only read O2 on one bank. However when tuning the engine I will test O2 in each bank by moving the sensor from one bank to another.
Thoughts?
Thanks
