There are two parameters in the latest version of the VCM editor that I'm unfamiliar with: Fuel/Oxygen Sensors/Closed Loop Enable/Enhanced RPM and Simplified RPM. The note mentions that at RPM below the Enhanced RPM limit the ECU uses "enhanced closed loop algorithms" and at RPM over the Simplified RPM it uses O2 sensor rich/lean thresholds. What are the "enhanced algorithms?" A stock ZR1 tune has 3000 and 3100 RPM for those parameters; my 430 HP crate engine E67 has 0 for both values so I assume my ECU never uses those "enhanced" algorithms. Should I care? Maybe my crate ECU lacks those enhanced algorithms?
Back in 2017 there was a forum post (https://forum.hptuners.com/showthrea...t=enhanced+rpm) asking for these two additional parameters among many others.
