When are you likely to be scheduled to go to LEAF-training?

Possibly in November?

Same as Toyota most likely with a torque sensor on the column that dictates assist as well as a link to the speed sensor to reduce assist at a higher speed. I have "hacked" into one of these ECU units before, the motors are very efficient and use only a couple amps at times. The Toyota EPS on the Yaris has a nice tight feel at freeway speeds and feels much more European than American cars, I hop the Nissan is similar.

I thought the techs were already to have had at least some training....the Intro to EV Tech course? Then they've got a 4-day Diagnostic and Repair course some time between now and December.

Anyone here own a mini cooper or did own one? Some EPS feels similar.

yes I have done intro to ev course it was more a saftey course than anything else. no word as yet when hands on course will be. from what i hear they will be launching in different regions at different times in the south east where i live will be the last i think.(proabally jan. or feb.) some of you will probally have your leaf before we get one at my dealership. that is one reason i joined because informed buyers like you all usally know more than alot of sales people and techs. alot of the info i have is in nissan in general until i go to the hands on course. any info i get i will try to pass on. i am certified on the hybrid altima even though they were not even sold in our area.

MINI E has a lot more road feel (less boost). For me the LEAF seems over boosted at slow speeds. But it is a preference. This could be to minimize torque steer in variable traction conditions (which can be a hand full in the MINI). A nod to the mass market nature of the car. My wife said she preferred the steering feel in the LEAF to the MINI after her test drive. Since all this is software these days it would be nice to be able to vary some of these parameters, or select say a "Sport" setting that decreases the steering boost for more road feel.

Yes - one of these days on the date of delivery they will let you personalize a bunch of these parameters.
