Re: Isspro ev2 questions
My EV2's are a bit twitchy, I think it is because they are electric sending units. I especially notice my boost gauge, I use to have autometers, and the boost gauge was mechanical and it was a bit smoother. I have ridden in some newer Peterbilt's with electric sending units and they operate just like the Isspro's. When I shut the truck off, my pyro temp stays at the temperature at the point which I turned the truck off, once I turn the key on again to start the truck, the gauges reset. As far as the dimmer, mine does the same, I turn the dimmer about half and it turns the gauges all the way off, don't know why, it just does, but I rarely use my dimmer. The lights are a bit twitchy in the morning when the volts are low, but once the glow plugs kick off they are fine. So everything you mentioned is normal, at least when comparing them to my gauges. Hope this helps.
