Wifeys car has an automatic, and it never proceeds above 4000
Even in closed loop it must be wasting gas . _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, May 16, 2008 7:03 PM To: [EMAIL PROTECTED]; [email protected] Subject: Re: Increaqsing Miata 1.6 MPG (lpc) 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. Randy 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 30s highway) I wonder if the 1.6 Miata runs rich by design or something. I mean its a lighter car with smaller displacement. Could the O2 Sensor be intercepted top force a leaner condition for cruising? _____ Wondering what's for Dinner Tonight?
