Cruise Status for VMSpc 2.x Step-by-Step setup

Cruise Status for VMSpc 2.x Step-by-Step setup
(Originaly Posted on 25-JAN-2003, by Herb Petersen)

I assume most of you use the Cruise gauge to tell you what speed the Cruise Control is set at.
Here is a little enhancement you may wish to try.

Enter the VMS Edit program.
Hit New.

Call the new guage "Cruise Status".
I call the abbreviation "CS".
Set the PID to 85.
Set Gauge Minimum to 0.
Set Low Red Line to 1.
Set High Red Line to 150.
Set Gauge Max to 150.
Set Low Yellow to 2.
Set High Yellow to 150.
Save the settings.

Start the VMSpc program.

Make a new Simple Guage.
Select Cruise Status.
Select location as Center.
Check only the Show Warning Lamp, box.
Set the color to Black.

Size the guage so all you see is the round indicator lamp in the square.

Place this square next to your Cruise Guage.

Now, when the Cruise Control is turned OFF, the guage will be RED.
When the Cruise Control is ON and active it will be GREEN.
When the Cruise Control is ON but NOT active it will be YELLOW.

Enjoy!

Herb

Thanks Mark for posting

Thanks Mark for posting this. Could you please explain what the numbers mean or are equal to?

Low Red Line to 1, High Red Line to 150, Gauge Max to 150, Low Yellow to 2 and High Yellow to 150.

And how VMSPc knows what to do with this to get the final results.

I had my ECM reprogramed for Cruise/Engine Brake to Latch mode, and at times i do not think the Engine Brake is coming on--just the Tranny downshift. I want to do something like this for the Engine Brake--Green Engine Brake OFF, Red=Engine Brake Switched ON . i made a Simple Guage using PID 40 (Engine Retarder Switches). I can't try it out though--Moho is in shop.

thanks, Ron

The Cruise Status PID works

The Cruise Status PID works like this. If it's all off, it reads Zero. If it's on, it reads 1. If its engaged, it reads 129. (There are other values possible, which give the status of the brakes and switches.)

Extarder/Engine Brake

It's easy to tell when the exhaust brake is engaging. Just watch your intake manifold temperature gauge. When the extarder activates, the temp will jump up to 50 degrees hotter in just seconds. If the temp stays the same, your extarder isn't working.

When my coach was new, the extarder didn't work, it was frozen up (among other problems). So even if you had a gauge for the extarder, it could indicate that it was working, but if the valve was frozen, it wouldn't actually be working.

As a sidebar to this: When it's time to shut off the engine, if the intake manifold temp is within about 50 degrees of the outside temperature, you can shut down, the engine is cool enough. (Thanks to Martin on this, I learned it from his seminars)

The Cruise Status PID works (almost)

I set up the cruise status as shown in the instructions. It seems to be working... _Except_ when I set the exhaust brake "ON". then the cruise status light goes back to green! Can you tell me the other "values possible", Martin? That might help me change the params in VMS edit.

Also, re another note in this thread, I tried the gauge for Engine Retarder (PID 47 on my engine, not 40 as shown in post by ronbo). What are the possible values/meanings for this one?

Interesting.

Your exhaust brake is triggering a "BRAKE" signal in the cruise system, which on most coaches only happens on the service brake. (You should see the same phenomenon when you tap your brakes.) It should add 32 to the value when the brake is on. You can verify exactly what is happening by monitoring the PID value.

The same is true for the retarder. Just make a gauge to watch the value and see what it shows when you turn the retarder off and on. The specific values depend on the model of the retarder - some folks have two-stage, some have three-stage, etc.. (Some have no retarder output.)

The Cruise Status PID works (almost) .. Interesting.

I figured it (the engine brake signal) was setting bit 5 of this PID. Any chance of allowing bitwise extraction of PID's? ;-)

(It should be a fairly common problem as the Cummins ISL engine becomes more popular.)

Hmmmm.

I'll have to give some thought about how to implement that idea.

I have the Cummins ISB with

I have the Cummins ISB with the Allison 3000 transmission. The documentation states that when ever the VG Turbo acts as the exhaust brake, "the vehicle brake lights will be activated".

OBDII plug adapter

Is an adapter available so that I can use the VMSpc in my Chevy Truck? In my truck I find a rectangular OBDII plug; but the plug I use in my motorhome of course is round. Maybe I'm Google searching for the wrong thing. Can someone tell me how to mate the two together?

Thanks!

Engine Type

Here is a search for you.

Cruise Status

I am having a problem getting the Cruise Status to work. It remains Green no matter what the switch positions. I set it to read out the value and it reads 64 with the Cruise Off and 65 with it on. I didn't drive the motorhome so I don't know what it reads when engaged.

Re:Cruise Status

Did you:

Set Gauge Minimum to 0.
Set Low Red Line to 1.
Set High Red Line to 150.
Set Gauge Max to 150.
Set Low Yellow to 2.
Set High Yellow to 150.

Indicator Color

I installed the Cruise Status PID and have the following problem. The green color is too dark. It looks nearly black on my screen. Can I select a lighter green from the color selections available (3rd swatch on 2nd row works for me). While I want to change the Cruise Status PID's green, If it lightens up the green on the other guages, that's fine also.
Dick Zeiter

I'm a frayed knot.

We'd have to do a bit of programming to make that happen. Meanwhile, I have another idea. Make the background color of the indicator the exact same green color. Your eye will see the contrast easily enough. (If you want the title of the indicator to be on a white background, just make a text box that says "Cruise", or make a second indicator.)

I learned that trick from a color-blind user.

Cruise Status Indicator Color

This is a great idea.. only thing is it would be nice to have other color indicators .. TO most people, yellow means *caution*; red means WARNING!

How about alternate colors (by gauge) for "red-line" and "yellow-line"? Maybe just another choice instead of yellow/red... say lightgreen/lightblue??

Cruise status light and Vista

I've been running the cruise status for years on my Windows XP Pro laptop and love it. I just recently bought a new laptop with Vista (jury is still out) and VMSpc seemed to install and run fine once I reset the engine, corrected the com port and resized the screen . One issue, however, the status light does not want to work. It comes on green and stays there. If I need to reinstall it, I cannot find VMS Edit to rewrite it. Any ideas about what happened?

Well, I finally figured it out. In the Advanced tab there is the parameter editor. I opened it for the cruise status and saw that all the parameters had been changed. I reset them to Mark's setting and it seems to be OK. I'll know for sure Sunday when we travel again.

Cruise status Variation

I found that setting the CS gauge like Herb posted but setting
low red line = 0
low yellow line = 128

I get the indicator to go to yellow when cruise is on and exhaust brake is on, red only when the cruise is off.

Cruise Status PID 85

TO update the above, here's the full list of settings that I use for Cruise Status (PID 85) with my Monaco, with ISL 400:

Set Gauge Minimum to 0.
Set Low Red Line to 0. ***
Set High Red Line to 150.
Set Gauge Max to 150.
Set Low Yellow Line to 128. ***
Set High Yellow Line to 150.

The *** lines differ from Mark's setup, may work for some.
