Try to keep the car in closed loop mode as much as possible (more on that in the advanced section). When you're done, you can click on the "MAF Adj: CombinedFT" menu item to see what the application comes up with. Review this, smooth the points as you'd like, extend the points to cover areas where you did not collect data and then hit "Save to ECU" when you're done. | + | Once you're satisfied that the requirements above have been met, you're ready to grab a datalog.
