#4255, "Tuning MsNs for fuel economy, how easy would it be..."
Thinking ahead here to when my MsNs is installed and everything is running smoothly, I was hoping I'd be able to do a simple adjustment via laptop and re-tune the car for fuel economy instead of power. I read that all you would have to do to accomplish this is adjust the AFR? I read 12-14 is good for high power but 15-17 for great fuel economy?
My question is this: Is it true that you can make a simple switch via the laptop hooked up to the MsNs to go from high power to high fuel economy? If so, what kind of fuel economy could you expect @ 15-17 AFR? I know this is TOTALLY dependent n how good/bad of mileage the car was getting BEFORE such change was made so let's assume it was getting 18/22mpg with good power; would like 22/28mpg be likely by robbing the car of all that power and increasing the AFR or do I just have this whole idea comnpletely wrong? thanks for reading...

True, you can add a switch to the unit for map switching, but a properly tuned vehicle should already be configured for both maximum fuel efficiency and power. You control how much fuel is expended with the throttle pedal, not the tune. A map switching switch is better used for switching between two completely different configurations (i.e. C16 and pump gas).

I'm planning on using that for E85 and 91
