So I notice that with my arduino bypass plugged in, the engine "feels" different with the check engine light off. Idle is a hair lower and there seems to be less torque at low RPM. I suspect the engine map is different when the check engine light is on. Logic would suggest that it may be partly responsible for lower fuel economy.
