The automatic certainly isn't helping anything as you probably use more
throttle to get the car moving than you would with a stick shift.

Wifeys car has an automatic, and it never proceeds above 4000

 

Even in closed loop it must be wasting gas..

The 1.6 ECU is very simplistic.  After 4000 rpm it goes to a single fuel
setting and, IIRC, ignores the O2.  To get maximum milage with the stock ECU
you have to drive less than 4000 rpm.  

 

Option 2 is to get an aftermarket ECU.  Option 3 is to put a 3.909 rear gear
or .75:1 5th gear to lower rpm.

Well I was researching the OTM Dodge Neon I will probably be buying, they
have 2 liters, are 300lb heavier, with 20% more horsepower and get 50%
BETTER gas mileage (high 30's highway)

 

I wonder if the 1.6 Miata runs rich by design or something. I mean it's a
lighter car with smaller displacement.  Could the O2 Sensor be intercepted
top force a leaner condition for cruising?
