Jaguar "Whiplash"

Our team has had issues with fried Jaguars in the past, mostly from drivers going from full forward to reverse too quickly. Theoretically, the Jags should cut off automatically when there's too much load on the circuit, but they don't.

Have other teams dealt with this? Does anyone have precise numbers (or a spec sheet somewhere with numbers) for how much "whiplash" it takes to kill a Jag? (eg, signal changing faster than 500%/sec or whatever)

We can easily program around this, using the same kind of trick everyone used for traction control for Lunacy, but we need a max-acceleration parameter first because experimenting to figure it out could get expensive...

Thanks,
Team 2877
