During the last final the car was fast then slowed then fast and so on . Almost like it was going from sensored to sensorless. Brand new sensor lead was in place. This also happened for the first two runs last week when changing the lead cured it and enable a qualifying time and two subsequent fast finals.

Today four good runs and then fast-slow-fast. Motor temps max at 42oC

Any ideas?? Anyone??
