Here is yet another reason why gauges are important.

For a while I have had a bad pin connection in my Coolant temp sensor plug. Which will lose connection and make my coolant temp show over 300. The dealer refuses to fix it becuse my commander plug runs in line with it and said that is the reason. what ever.
so when the truck sits for 8 hours or more on really cold days the connection will not be good and make my gauge show over 300.
Usually it happens when I first turn the truck on then goes away quick. I get the little engine light and the check gauges light.
Now to get to my point.
Because I have the commander I can double check the trucks coolant gauge. Well I had an accurance yesterday when I started my truck. I just happened to be looking at the commander when it showed 300 degrees. I looked at the truck gauge and it hadnt moved. It was at least 5-6 seconds before my trucks gauge read what my commander saw and then it coded and the alarm sounded.
I was like holy cow! My engine could have been blown by that time.

So if you dont have gauges and you are modded, get them

 

So your message is that the Commander can relay information 5 seconds faster than the factory gauges?


Oil pressure might be a good thing to have a shorter warning period on. Don't see 5 seconds making a difference on anything else...

 

if done repededly it could be bad.

The commander uses the same senor as the factory gauge does.

 

If done repeatedly what could be bad?

Coolant temperature rise should be slow enough that a 5 second delay isn't going to hurt anything.

Does boost have the same 5 second delay? That'd be annoying.

You know that some the ECM controls and reads a lot of parameters, like injector PWM, rail pressure, TPS, boost pressure and engine position, in milliseconds, so any delay is probably just in the translation to the gauge. I only see delay being important if the ECM was programmed to derate or kill the engine in the instance of an extreme parameter. But I don't see a five second delay in coolant temperature being enough to hurt anything.

The question would be whether the ECM reads oil pressure, if it's programmed to kill or derate the engine if the oil pressure drops, and if so whether or not it kills it faster than 5 seconds.

It's not that big of a problem either way. I bet that it could do it within 5 seconds no problem if it was programmed to do so; who knows how it's programmed from Dodge?

 

uh, if it went from 180 (operating temp) to over 300 degrees in 5 seconds while I had it mashed to the floor. yeah thats an issue.
the other thing is when that happens to my truck while it moving and it does make connection quick enough it runs like crap and actually slows me down, I cant remeber if it shut me down or not but something weird happens.
