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