I can monitor both at the same time, but the LTFTs are more important here. I also monitor knock, which never happens as far as I've seen, since I run conservative timing. Scan gauges are awesome, you can change what you are monitoring off the OBD buss on the fly and log two variables at a time. Anybody who mods their car this extensively should be running them. Anyway, if I am in tuning mode, I use the Diablosport to log all the important things at the same time. Then I can make graphs or play it back on the computer and send the data to my SCT tuner.
