ICP Pressure at idle (hot vs. cold)

I changed my parameters on my Insight CS to read ICP and was watching it over the past few weeks. It seems at idle when the engine is cold, my ICP is about 650psi and when my engine is hot, it is about 570psi. That's 80psi difference just based on oil temp. What is everyone else seeing?

Mine, at cold varies with ambient. But at hot, will be right near 580.

I can watch the ICP lower as engine temp goes up.

I was going to type what I recall, but heck, I'll go start my cold truck now, back in a minute.

EOT 60*

Engine cranking = 1750

Started timing.
At first idle=1020
15 seconds = 1007
30 seconds = 1001
45 seconds = 995
60 seconds = 975

At the end of 60 seconds, ECT 61.8

I run Rotella T-6

Again, hot is always around 580.

Thanks Dave. That's not good with the code. I hope it's nothing serious.

My truck was idling the other day and I noticed that it had a miss to it. It wasn't a consistent miss and only happened once at that time and then was fine. It did it one other time a bit later and again was perfectly fine after that. It's the first time in over 2 years that I was nervous about my truck...

BTW, I didn't even have time to check the Insight to see if ICP dropped when the "miss" occurred. I even had to ask my buddy if he felt it miss because I wasn't sure I had felt it.

Thanks Tom. I wish they (Edge) could update their software to do the conversion behind the scenes and just output the pressure. I also wish they would add the Exhaust Back Pressure PID to be able to be monitored as well. You know what they say about wishes...

I did this test this morning on my CTS - cold start was just over 1000 and warm is 575-585.

It also goes right in line with oil temps - as the oil temp was rising the ICP was falling.

For whatever its worth that is what I found.
