I'm wondering if anyone has come across a way to get the same performance of an i3s from an i3?
I've googled and searched this form and can't find anything.
Others have reported that the part number for the i3 and i3S motors are identical which means that the same motor is producing more power. I haven't read how this change is implemented. It could be different motor electronics or just different software.
Not sure what you mean by this. There are no electronics in the wheels.
My interpretation is that traction control is now implemented directly in the motor electronics rather than in a separate traction control module. Nevertheless, traction control is much improved in newer i3's.eNate wrote: ↑Sat Oct 05, 2019 11:46 amIt's possible I'm interpreting this wrong:
"...the control process is now calculated directly in the powertrain instead of in a remote unit requiring long signal paths."

But to me this reads as new electronics are involved (including new physical location), maybe not at the wheels, but somewhere directly in line between the geabox and the wheels.
Maximum power output doesn't seem to have been decreased in our 2014 BEV. However, traction control was modified to prevent a wheel momentarily off the pavement from suddenly spinning to high speed before returning to the pavement (e.g., when driving down over a curb). Also, the maximum torque when starting to move from being stopped or at a very low speed seems to have been reduced thus reducing the shock on the motor mount.
This could be confirmed by comparing the motor mount parts numbers at realoem.com. A stronger metal motor mount began being installed on 2016 i3's, so the same motor mount could be used on the i3S. It is reported that the i3S isn't any faster from 0-30 than the i3 but that it has increased power above 30 mph.
At least one i3 owner installed i3S flares and remounted an existing ultrasonic sensor so that it wasn't covered by the flares. However, adding ultrasonic sensors where no wiring likely exists could be challenging.scsikid wrote: ↑Sun Oct 06, 2019 6:56 amI know the fender flares are a thing on the i3s, but then I just read the parking assistant loss which actually is a feature I was looking for with having a tight garage space. Relocation of sensors that are currently in position of the fender flare mounting doable?
