If your trying to make your car driveable, which means a good idle and cruise AFR, tuning with the front o2 sensor is fine. Your just watching it cycle from rich to lean (.8v to .2v) and making sure the ECU is trying to maintain a stoich mixture. Get the car driveable so you can get back to North Carolina and install your WB o2 sensor, then you can start doing WOT tuning.

Watch these demo videos, if you do EXACTLY what he says your car will drive just fine all the way to North Carolina.

When I originally posted I was at work and could'tn view your log, I just looked at it though and have a few things for you on top of what I mentioned above.

- Your launch limit is 7k which is WAY too high, bring it down to 4.5k to 5k.

- What injectors are you running, your global settings are -34% in your logs but you IDC's are 93% towards redline, I'll take a guess and say you've got 660's in?

- Your MAFComp sliders need adjusted, post an idle log after you car has warmed up (180* coolant temp) and log AirflowPerRev and MAFRaw. For this you can really watch that V3 Fuel Trims demon video, this will really help you get those sliders where they need to be if you want to do it on your own.

- Any reason why you have your AuxMaps enabled?

- In your ECU Inputs tab I noticed you have the front o2 sensor set to WB, you don't have a WB yet so why?​
