====== V3 Hard Reset ======

In some rare situations, it may be necessary to do a hard reset of your V3 flash device (reset back to original defaults).  The following describes how to do that.

  - Turn the ignition on (don't start the engine)
  - Wait for the CEL light to go back off after a few seconds just as a check that the ECU is up and running normally.
  - Press the throttle to the floor and keep it there as you cycle the ignition key off and then back on 3 or 4 times. I usually go for 4 but 3 is the minimum.  Pause for just a moment between on/off switches (about a 0.5-second pause, but not more than 1.5 seconds).

Once you have done that, the ECU should reset back to the hard coded defaults in the chip.


Additional notes:

  - The vehicle speed must be zero.
  - ThrotPos must exceed 72%.  (Verify by logging.)
  - Beginning with the ignition on but the engine not running, the minimum sequence is:  turn the key off (first time) for 1/2 second, on for 1/2 second, off (second time) for 1/2 second, on for 1/2 second, off (third time) for 1/2 second, then on and leave on. (The speed of the off-on should be about like a clock going tick-tock or a bit faster.  Failure to reset usually is caused by toggling the key too slowly.)
  - If you initiate logging prior to performing the reset sequence, the logging will halt (the seconds counter will stop updating) the instant the reset happens.
  - With firmware v3.18.205 or earlier in the ECU, to be sure that the default settings are properly saved after executing the hard-boot procedure, use the PC app to modify any configuration value and Save to ECU before shutting off the ignition.
