Saw 114A briefly at about 170V which was just over 19kw but it gave a P1440 error after a couple of seconds.
This is a generic IMA system problem. Interesting that is wasnt directly related to voltage or current sensors that we are spoofing.
I suspect this is linked to
1) A second current cross check perhaps in the phase sensors? Not sure if that's likely or not.
2) My BCM current hack pot is not man enough to deal with the BCM current sensor 5-20ma output so I need a 300R resistor capable of a couple of watts (same as stock parts).
When using 50A of assist in top gear it worked for a good 10 seconds before error occured. More gradual heating of my tiny pot?
With WOT error occurs in couple of seconds max.
I might also try setting the current limit back to stock and just using the voltage hack so the increased voltage gives us more power rather than the increased voltage & current.
180V at 100A is still 18kw
Cells are so cold <0C could be due to voltage sag under load being so high IMA thinks there is a problem somewhere like a bad connection causing voltage drop. Drop from resting V at present is around 30V at 100A, the higher the system voltage, the higher the percentage voltage drop becomes.
Anyway it hasnt blown up, just got a bit more fiddling to do. DC-DC converter seems happy.
Desperately need some warm weather but no nope of that for a few weeks.
