DataMaster Help

I'm looking over my DataMaster log file and I'm noticing Split BLM's at idle. Just want to confirm when looking at the "LTerm Count" values which side represents the Driver side and which represents the Passenger side?

What I mean is the "LTerm Count " has 2 boxes a left side and a right side. I need to confirm that the Left Box is for the Driver's side and the Right Box is for the Passenger side..is this correct??

He has a newer LT1 car. O2 sensors on both sides. Split BLMs not unusual. Some times new O2 sensors may fix it. Among other things.

Yes STerm has 2 boxes as well. Just need to verify if the Left Box represents the Driver Side.

Frankie, I think your overthinking this a bit for tuning purposes. Have you opened the histogram and clicked long term? In a properly functioning engine both o2's should be producing similar results. If they aren't then you have a fault. For tuning just use one side from the histogram and modified the VE tables.
I built a page here for the L98 using Datamaster if it will help you.

Still looking for an answer to confirm which box in the "LTerm Counts" represents the Drivers side. Need to isolate which side is causing my Split BLMs

Unplug an injector while logging the car, and the answer will be apparent. The helps section only says this:
"For SFI systems, this is divided into left and right side values."
However, this statements seems vague at best. Unplugging an injector will lean the bank and values will rise to tell you which side. Just don't put a load on it while doing this.
