Before I start messing with my ECU I want to get some basic instrumentation in place (manifold pressure and WBO2). I'm interested in hearing what you guys do for WB02 monitoring on your 2.7tt.
I was considering getting two AEM UEGOs, one for each bank, but I feel that may be a waste of money. However, if I go with a single gauge, I can only monitor a single cylinder bank. Is there a measurable difference between the drivers side and passenger side banks, i.e. is one bank more susceptible to lean conditions? I know with certain engines there can be specific cylinders that are inherently lean.
Thanks for the feedback.
When approaching the limits of the stock pump it is possible for the driver's bank to run leaner. For that reason I monitor that side (bank2). We either log both wideband and me7logger and overlay, or connect the wideband output to an unused input of the ecu and edit the .cfg and .ecu files in order to display the data.
