HyRev 7500 ECU box

Earlier in this thread it was mentioned the Chrome ECU should not be used on the street [ under 2000 rpm in the MP book ]. This unit uses a 0.25 ohm bal res, lower than the other boxes. I suspect the reason is that the coil current 'on' time is too long at low rpms; this coupled with the low resistance bal resistor could overheat the coil.
