ah, your good then. Never realized Autometer had a complete seuplike that
I'm not so certain, that appears to be a gauge only. The controller is what is needed to datalog and provide the signal to the gauge. To 94coupe, go to the Zeitronix site I referenced in post #34 to see what all the components needed are. The gauge is not necessary but you will need a laptop to run the WB software and see the AFR readings.
