So is that to say that the ROM still to this day hasn't been completely decoded? That sucks!!
The evo5/6 has been to maybe 75-80%, more than enough to get a car running. The 4g93 is maybe 25%, but enough for what the car is.

Q: When in open loop, the only thing that changes is that the ECU no longer references the 02 sensor, correct?

Correct, it used the same calculations of air temp and flow, and rpm, but no longer attempts to put effort into making it stoich/reading the narrowband
