View Full Version : O2 sensors before turbo

I'm not sure how familiar most are with a Syclone style turbo setup, but the exhaust manifolds face forward with a crossover pipe in front of the engine where the bank 1 NBO2 sensor is. The turbo sits on top of the R exhaust manifold and the turbo goes into the down pipe where the bank2 and wideband sensor is.

I tried using the output of the AEM UEGO in narrow band mode, but it didn't match the bank 2 sensor. As far as I know, there won't be a way to get accurate readings for each bank and honestly, the life expectancy of the AEM sensor isn't that great anyways.

I am thinking about just assigning all of the injectors to bank 2 but I'm not sure this the best idea, especially since I eventually plan on installing a high resolution crank sensor and adding individual coils later.
