While road tuning using the Infinity and PnP harness, using the base map, I randomly get throttle cut offs. I have the DBW channels set to log now through USB but last time it happened the log file was 0kb. The one thing that might be the problem is that I did the DBW calibration when the cat battery was around ~12-11.9v. I plan to charge the battery up to full and use a 12amp battery charger hooked up before performing another calibration. Is the calibration something that could cause DBW errors at random? At other times, the DBW works great and the Throttle Position follows the DBW target pretty well.
