My throttle mapping issue is not time-dependent, so it's not any kind of "delay". It's not "dying for a second then picking up". That sounds like a hesitation. There's no delay/confusion caused by positive boost readings. The ECU is recalibrated to account for MAP readings into the positive boost range.

Also, "eco mode" is not a mode that the ECU tries to operate in. "eco mode" is simply an indicator of whether you are currently operating the vehicle in a way that makes for good fuel economy.

My problem is that there is a wide range of throttle positions (25%-95% pedal position) in this particular situation (freeways speeds in the 2700-3300 rpm range) where pressing the throttle more will never cause the Jeep to accelerate more. The above 95% pedal position, I SUDDENLY get full throttle boost and acceleration.
