VCM Remapping & Recoding

The Vehicle Control Module (VCM) in a Nissan Leaf monitors and controls most aspects of the electric drive-train.  The battery controller, inverter, charger, etc, all report to their boss – the VCM.  Therefore VCM reprogramming opens up the following possibilities:

  • Replacing complete battery packs without needing to open the pack to fit the original Lithium Battery Controller (LBC)
  • More aggressive regenerative braking in B or Eco modes – reducing or even eliminating the need to use the conventional friction brakes under normal driving conditions.
  • Simplify EV conversions using Leaf parts, by reducing the number of unwanted controllers/parts that must be retained as part of the transplant
  • Higher performance

We have made considerable progress with the VCM found in the 2011/2012 Nissan Leaf. Using tools that we have developed in house, we are now able to reprogram these ECUs via the OBD2 port.  However we are not yet at a point where we are ready to offer our VCM reprogramming services to the public.

The VCM in the 2013-2017 Nissan Leaf is considerably different to the earlier version.  We have not shifted our focus to these yet.
