Roadworthy Some of the maps used for fuel economy for the Cobb Accessport on Mazdaspeeds do have a LOT more spark advance across the entire powerband.

Roadworthy The ecu will always try to compensate. By doing this mod, you're pushing the advance limit higher.

For example: We'll say the ecu can do a max spark advance of 60*. If the ecu detects knock, it will scale things back until there is no knock. Push the physical connection to get, say a maximum effective spark advance of 64*.

Your engine now has the ability to run a higher spark advance but still be able to scale back in the event of knock detection.

Highest power output for combustion occurs just before pre-detonation.

9. Make sure crankshaft position sensor is in the fully advanced position (take off front passenger tire, look to bottom left and see if the slotted sensor is pushed down as far as it can go)

some people on here used 16s with aero covers for winter wheels after using 18 Ti wheels and saw a 4 or 5 mpg improvement. But it makes sense, smaller wheels weigh a lot less. more air and less aluminum and rubber. Also the smaller wheels are narrower so less surface area touching the ground to steal momentum.
