Twin Oxygen Sensors?

I was wondering if there is a way to add a chuck of code to the '7730 ECM PROM so that I could run a set of modified 3.4L exhaust manifolds in a twin turbo/divorced twin plenum set up I am planning on building.

That way I could have an oxygen sensor in each log and have a much more honest reading of how each side is running.

I tried the search, but it seems that nobody else has had this particularly crazy idea before.

Re: Twin Oxygen Sensors?

It's been discussed.

The general consensus is that the entire fueling code will need to be re-written to take advantage of it, and the gains would be extremely minimal since there is no way (in the '7730) to control each injector bank independently, seeing as there is a single injector driver in the '7730.

You're best off using a single sensor in one bank, and if you want monitor the other bank independently, or with a dual channel WBO2 set-up.
