Hi guys. i have a batch fire 1992 corvette. My question is with tts datamaster, does the left reading correspond to the drivers side and the right one correspond to the passenger side? In the tts instructions, it just says "for sfi systems, this is divided into left and right side values". It doesn't have any notes on what they mean for the batch fire setup.

In short, upon startup of my car, one o2 is in the 400's and the other is much higher, in the 500's to 600's. Ideally I'd like to know which bank is richer so that I can inspect the plugs and wires (again). In my case, the right reading is the high one.

 

Could just unplug one, to see. Unplugged side should show ~.450mv all the time.

 

thanks Ed. Great idea- I'll give it a go

 

Yes left side in Datamaster represents driver Side
