If you interrupt the regen triggered at 65%, the stock tune will wait until the 80% trigger for the next regen. If the regen triggered at 80% is interrupted, the next regen will attempt at the 90% threshold and you'll get the EVIC message.Not true of my truck... I drive short trips and have frequent regens, which I occasionally monitor. If I shut down during a regen, it just takes less time before another regen starts. Mine seldom gets down to the 8% regen completed, but I have never had the EVIC message to drive on the freeway. This truck is very forgiving of incomplete regens, by my experience.
