Good work. This is an extremely important feature for people in states like PA, where we have annual inspections and they check the readiness via OBDII. That's why I raised the question a few weeks ago about your O2 sim method for V3 (and at that time you thought it was fine as it was, I believe).
Anyway, this is good news. Did you say that the feature is able to be toggled on or off by the end user, since people who don't have or intend to get DPs would have no need for the trickery?
