Just wondering if anybody could answer a question on the Ford type ECU in the 6s.

On some ECUs when you do a reset the ECU defaults to a "Best" setting (Max advance, ect) and then learns/adjusts down as the sensors gather data (ping, ect). Others go to a "Worst" default and then learns/adjust "better" from the sensors.

Any idea on the Mazda6 s?

On the EEC-V computers I am used to, a reset would typically yield more power and then the power would go down over the next 50-200 miles driven....

The Mazda6 is using an EEC-V computer, but call it a generaion II EEC-V.. I am not sure if this computer acts the same as other Duratec EEC-V computers found in cars like the Escape, Taurus, and Cougar.

People say to reset the computer before dynoing or in between modifications. Or if you install a new part, like an intake, to reset the computer so that it learns all over again, but also takes the new part into account, etc.

how do you reset your computer yourself? unplug the battery for 1 minute?

hm... so installing the headers with a complete exhuast will be drastically improving the performance after reseting the ECU???

Drastically? No, resetting the ECU just speeds up the readjusting to the new parts. Starting with a clean slate, so to say.

The only problem is, will this cause the stereo to no longer work? I know it's a weird question, but I know on more higher-end Mitsubishi's, and few other makes, if you disconnect the battery and don't keep a constant supply of power to the car, the stereo goes into a security lock-down mode and requires a certain code to unlock it again.

Doesn't the ECU also keep a permanent memory regardless? We've replaced dozens of ECUs over the years, but everytime we replaced the ECU and PROM chip at the same time, we had to ship if off the dealer to get reprogrammed because the fuel maps were way off, this was on a 96 Cadillac Deville.

Is code resetting different from resetting the ECU? Everytime we reset a code, or set of codes, we break out the $2,000 Snap-On scantool to reset them.

No, but you will lose your radio pre-sets. The feature you are thinking of is anti-thief. The 6 radio doesn't have that feature.

Yes, it keeps the default fuel and timing maps, it just forgets all that it has learned. IIRC any error codes are still in memory until cleaded the proper way.

The ECU would probably adjust to any new parts in time, reseting is just believed to speed up the process.
