The Renesis does NOT run rich

Stoich produces "ideal" combustion theoretically, but a point richer produces more torque.
The additional torque is generally greater, as a percentage, than the fuel used.
MBT>stoich
It is flame speed and combustion efficiency. At stoich, there is still a lot of left over oxygen.
BTW - In reviewing the tables above, keep in mind that "commanded" values don't always equal "output" values.
Mazda was less concerned with "nailing" the MAF calibration than we are since they had such a wide deviation to deal with.

Well, my mileage is fantastic! I spend a lot of time cruising north of 6,000rpms and i still get 20+ And at american highway speeds I can get better than 25 pretty easily. My only relavent mods are coils, cat delete, and tune.
and FWIW my compression is nice and balanced, but a bit on the low side. IMO this car can make 30mpg. I've had 27 a few times. I think with the addition of the right choice in wheels, clutch/fly/PP, removing the 120lbs in my trunk, and a few other minor things - that this car could make 30

Are the tables only divided into the 1-2-3 and 4-5-6 pieces? Is there a way to do a 1-2-3, 4-5, and 6 map? If so, it would leave an option of creating a cruising-only 6th gear map where one could push the lean limit.
Perhaps another way to eliminate lambdas under 12.5 or so would be to water/meth inject, to get a higher octane for detonation-prevention. However that would require a fairly sophisticated method of determining when that injection should occur.

WV to FL is mostly downhill.... I got 40MPG last time I did it in a Tercel mind you.... but still.
All the Fuel Maps can have a cruising area set up - since the load and RPM create the scales.
Even in 3rd gear, a load of less than 30% constitutes cruising in most situations...

(I'm just going by what some older builds of ATR offered, but I assume it follows the stock pcm logic)
