re-learning ecm? - Toyota Yaris Forums

curious question CTScott, is it good for a manual tranny? I drive normally, but because of inconsistent fuel economy figures sometimes on a drive it like a stole it manner (some nights/highway).

I still can't figure out the best shifting points that will keep fuel economy figures high. the manual states the best shift points but they're usually on 3k rpm point. are those accurate? or should i unplug the negative terminal then drive normal 100% (or for most of the time)?

The tranny related reset is purely for the AT. If you do a throttle body and/or MAF cleaning, doing the battery disconnect reset is a good idea to reset the fuel trims.
