Pyro flutters?

My pyro started fluttering around 900' and would shoot up to 1300'. Any ideas?

Re: Pyro flutters?

could just be bad gauge, resistance is what they work off of iirc. or it could be the probe it's self.

I think it is the dreaded pyro surge. Buy a TN as I hear they can't surge. J/K!

Mine did it a couple times. It was the gauge.

Mine was autometer. On the Isspros with that crazy box who knows.

Re: Pyro flutters?

That crazy box on the Isspro is just the same stuff that Autometer stuffs into the gauge itself. I've had WAY better luck with Isspro's than Autometer. Isspro are factory in almost all of our work trucks.

Re: Pyro flutters?

My autometer is doing that now too. Works fine most of the time, then it'll peg out, and bounce around. Stupid gauge. As much as they cost, it should last longer. Bad part is I dont want to switch brands, cause I dont want to replace all the gauges to match.

Re: Pyro flutters?

Yeah, it is usually a bad ground causing it. Unfortunately that bad ground may be through a bad connection inside the gauge!
