Isspro ev2 questions

So I just got done installing my isspro ev2 gauge kit from diesel manor and I have a couple of questions. First, the gauges seem to be a bit twitchy, especially the boost gauge. I got boost and pyro, both are electric. Is there some sort of break in period or anything? It seemed to get a bit better once i drove a little. Second, when i shut the truck off the pyro stays at the last temp it was until the truck is started again. Is this normal? Third, the lights on the gauges seem to pulse at night (the lights) unless they are turned all the way up on the gauge dimmer switch. The gauge dimmer switch only uses about a quarter of the knob unitl they go blank (no light) for the last 3/4 of the knob. I have them tapped into the dash dimmer as well and when I dim the dash lights they only dim slightly until they go to this inbetween flash type thing (same this as when i use the gauge dimmer) and then they go blank when the dash keeps on dimming.
Is this normal?
Does it sound like the gauges are bad or the wiring or something? I followed the instructions exactly.
Any and all help appriciated.
Thanks,
Dan

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.

Thanks for your reply. I can live with all of the above, just things i noticed and thought if this is not how it should be I better get it fixed right away. The more i drive, the more i relise that i dont really use the dimmer anyway... Guess it would just be nice if they could dim low but not the end of the world by any means.

Re: Isspro ev2 questions

They're LED lit so that is normal for them when you dim them down. It's like trying to put a dimmer on a florescent house lamp. They will flicker if dimmed below a certain point. I have them in my truck too and they do the same thing. As for them stopping when the truck is shut off, that's also normal. They use a stepper motor for the needle movement, so when you shut down the eng. the gauges loose power also. Just like your windshield wipers. When turn the key off, your wipers will stop in mid-motion. It's only when you re-power the ign back up that they'll go down again. Let me know if you have any other questions.

Didnt even think about emailing you guys about this. Thanks for the reply and thanks again for the kit.

Re: Isspro ev2 questions

Looks like the answers have been covered, but one question for 03machstock - does your truck have the auto-headlight option? If so, then it has a different voltage vs light output curve than the standard headlight versions, and that is why the gauges don't dim at the same rate. You can adjust this curve using the EV2 programmer R82003 (which is also used to activate and adjust the warning lights), or you can send them in to have us change the curve for you.

My truck does not have the auto headlight option. Just off, parking, and on. No Fog or auto. Does this still affect anything, or are they set up for my truck as is.
Also, the more i drive it, the more i realise i leave everything full blast anyway so its not really an issue. These things are sweet though!
