I've been working on this gizmo over on IC and some of you might be interested.
IMA Current limit and/or boost device. - Insight Central: Honda Insight Forum
Basically it reduces or increases the car commanded assist or regen by upto 100% using two adjustable pots.
Simple four connections in the footwell and can be mounted on the dash.
It can prevent the car stressing (overusing a weak battery with high assist or regen) or it can be used with a good battery to boost assist or regen levels.
