I 've made the same request at ScanTool.Net to add audio alarms. Yeah you can have visual warnings but does nothing if your focus on roadway conditions and can be looking at your gauges. So if it visual warning I might not ever see it on either my OBDLink or Quadzilla because the position they are sitting in.So audio warning is need to alert me to out of range problem. I've gotta drive and don't always have a co-pilot to watch the gauges.

Factory feature? 

 

I am not following.  

Yes sorry, not sure what else you guys talked about 

 

That is awesome on timing stuff, is it not available to general public yet?  I haven't been driving my truck lately as I got a little car to get around, plus it's been pretty cold. But I would love to try it some time if you don't mind shearing it. If it will be available soon then I can wait, thanks for the offer I feel special. And great video on explaining how things work, made some things clear. Did you make the video?

You are a man as usual, just when I thought wow finally quad is where it should of been long ago, you and quad keep coming up with better things, :thumb1: it's getting hard to keep up but definitely worth the wait. Glad I didn't get rid of my quad after they left the stage few years back. Pays off waiting sometimes.

I am betting dimes to dollars that once temp comes back up boost will read right again.  I don't know that there is a way to solve the issue.  

 

I could make it read 0 right now, then you would have a 2psi delay in the summer.  I am not sure what is worse?

When I did that screenshot the IAT temperature was 85F now it's 100F so the sensor isn't cold. After a period of high idle it still right at 90F for IAT.

 

I admit this morning at -31F outside I got IAT down to as low 18F that's cold and would say that holds true.

Only thing I know is that in the summer the reading was correct, now everyone seems to be off by 2*.    I would say this is because the ECM has an internal baro sensor, so IAT sensor temp wouldn't change baro.

 

HOWEVER,

 

I just reviewed the SPN's for 65270, which include boost, IAT, and Air filter pressure......   There is another SPN for Barometer, but I am assuming that maybe our ECMS use "air filter pressure" as baro.  So I coded up that and I will test it at some point to see if maybe we can read baro.....

I wasn't saying IAT temp was alyeri,g the value but if the IAT temp is warm so is the MAP sensor in physical temperature being they are just a few inches from each other.

 

Now considering temperature of the ECM now that might be something. :think: Is it possible the cold is messing with hardware of the ECM?

I think the ECM is using a sensor built into it plus battery temp or something to calculate baro pressure.  The ECM would not be using values from a sensor in the intake track.

 

We will see if there is a baro reading be reported.

So I coded up some stuff to read baro.

 

Baro sensor reports 0 all the time haha

 

Air filter pressure ( same PGN 65270 as boost) reports 36 all the time when calculated via the standard in the j1939 standards.  

 

not really sure what to make of that.

The only sensor we've got that that can see any pressure at all in the intake tract is the MAP sensor. Just getting back to the simple way of looking at stuff there is only a handful of sensors on these trucks. MAP is the only one that can measure pressure for the boost value. The ECM is a seal tight can so I didn't think there would be a baro number available. As for air filter pressure there isn't a sensor like the CR engine before the turbo. So that is out.

So if there is no baro sensor then how does the cummins ECM handle altitude?  Does it even?  

 

Why is it that the early trucks map sensors take baro into consideration, yet cummins switched sensors on late trucks to ones that don't consider baro?  

 

Seriously odd stuff going on.  I can make it show 0 psi right now, but in the summer it will have a -2* offset.  Nothing has changed in the sensor offset since summer.
