Ok, Put on your thinking Caps. Question about monitoring a Non-DDEC engine

[bevans6]

these guys are the leaders in entry level price point (under a grand for a beginner system, which is cheap!) data aq. systems for race cars.  and their stuff is good, reliable and it works.  http://www.aimsports.com/

You can get various analog to digital pressure and temp sensors that you could use for various things, speed related things are done with a square wave input, wheel speed for example is a magnetic sensor that picks up a metal object that rotates and passes the sensor, so you could do road speed and rpms.  it all feeds a dash, there is a download ability so maybe you could feed the computer or just use the dash.  You can buy whole systems from these guys for the cost of a couple of sensors with other systems, fwiw.

Why not go with a Murphy system a system that been in the marine and industrial world for years on mechanical engines


good luck

Dallas all this baffles me and at the same time brings back a fond memory of many moons ago.
Back when Robert owned buses and Dad & I worked for him he had old MC9's and one in particular had some serious ground problems that we never could catch all of!

Anyway when you turned on the headlights or A/C the temp gauge would go up 20* for each turned on. George Ford (god rest his cantankerous soul!) was one of the drivers and he'd been to Tunica all day. He called me from his last stop on the way home (K-mart in Jackson) and told me "Bryce this bus is running 225-230*!"
I told him "George that is impossible I just put new shut down stats on that bus last week and tested them to boot!"
He said "Well I'm tell'n ya that is what the gauge says! And I want you and yer smarta** uncle to know about it, and don't blame me if it blows up. Because I told ya all about it!"
I told him "George stop and go check the temp gauges in the rear (one on each head!), and see what it says!"
He responded "I did that already when your uncle told me the same thing, and by the time I got back ther it was only showing 185-190*, but when I got back on the road it shot back up!"
I told him "George it will be fine, come on home! It has bad grounds and if you have the A/C and headlights on it will show 40* hotter!...Not to mention if it was really that hot it would have shut down on ya already!"

He got mad and said "Well how the He** am I supposed to know that? What am I supposed to hire a little man to ride back there and have him call me if it gets to hot, or looses oil pressure!?"
I laughed my butt off and responded "No just have him watch both temp gauges, we've never had a problem with the oil pressure! So you'll only have to pay him half as much since he'll only be watching temp gauges and not oil! "

OH he got mad cussed me and my uncle while hanging up on me!

I still wanna know how much he paid that little man, and if he needs extra work these days!

It's the nature of electrical gauges, if you have a problem the temp will read high and pressure will read low.

I have that problem in my motor home when I turn on the lights.  I haven't been able to find it yet, but I no longer get too exited about it.

You don't have to monitor it all the time.  Obviously, such a system would have voice alerts of any potential problem.  You could also have voice query, "System, what is the oil pressure?"

Hmm....sounds scary to me  GOOD MORNING DAVE!
