Cobb had no trouble feeding his pack with 2 kW constantly, but 4 kW caused problems when driving slow.
I believe that was because the IMA system has no way to spend 4 kW on average when driving slow, so the voltage must have risen too much.

So it looks that whatever the current does, if the voltage is good the system will not cause trouble. And if it does I can reset the codes with my UltraGauge.
I would not have to worry about that, as in my setup the current strength will depend on the voltage drop compared to the parallel pack voltage. When driving slow the IMA voltage should float around the base voltage of the parallel pack, and the current would be low.
