truck falls flat on face during shift
07 ford f150.hpl
wayne's 07 f150 7-31-19.hpt
trying to make some minor adjustments too this 2007 ford f150 5.4l
when it goes to shift at wot from 2/3 or more commonly 3/4 the cluster stops reading, the radio cuts out, and abs module quits responding. The second you let off the gas pedal it completes the shift and everything reads again. ive tried adjusting the wot shift points and it doesnt stop this system.
through logging i have noticed that when it occurs. the injectors stop and o2 sensors stop reading. what am i missing?
near the end of the log, the last wot run really shows the issue

Yea the 3v motors have a common issue with the alternator doing weird stuff causing strange issues. Glad you got it figured out though.
