It reads 2.5V, 99-100KPA, KOEO. It has already been confirmed through HP Tuners the missing parameter and they are working on it. The settings are there for previous ECM just were never implemented...
All of those are set, the problem is P2074 which is a TPS MAP correlation. As soon as we raise the linear KPA to reflect the new sensor, code trips.
