A complete budget version of an analog gauge kit cost about $300. I doubt there is a good location for gauges to mount in the cab. You can get a mult-display digital gauge that is smaller.

Does anyone know if the transmission temp is available via ODB2? Trans Temp, Boost PSI, and EGT (known as a Pyrometer Gauge) are the 3 things to watch when towing heavy or running hard.

Installing a Pyro gauge involves drilling and tapping a hole for a thermocouple sensor in the exhaust system. The closer to the exhaust ports, the better. The exhaust manifold is preferred.

Re: 2014 diesel production

Well a lot depends on whether EGT or CHT is available on the OBD-II connection. If so a sensor is already in place and all you need is a readout.

A good complete system will run US150-U$200 plus installation. Personally I prefer to mount the sensor just downstream of the turbo. The relative temp is what you look for and do not need to know the exact peak. If you mount upstream and anything fails you could wipe out the turbo. Not cheap and unlikely to be covered by the warranty.

That said I prefer to run any engine on the cool side of spec and not to exceed 200F coolant temp. Diesels and particularly TDs with aluminum heads even more so. It makes a difference when you tend to keep vehicles for decades.

Would prefer to run my Pentastar about 15F cooler but AFAIK there is no 180F or 185F thermostat available. Please let me know if one is available.

Re: 2014 diesel production

@ Excursion-
The transmission temp is selectable for display in the EVIC. I recall reading a while back that " Gauge A' and 'Gauge B" were also options but I haven't seen any reference to those recently.
I would like to be able to read engine oil pressure and engine oil temp concurrently also.

Thanks. I'm sure we'll know more in a few weeks when they ship. It would be awesome to have everything available via ODB2 although I doubt it.

Regarding EGT sensor location, there are pros and cons to pre turbo and post turbo. The issue with post turbo temps is the drop in temperature across the turbo. It is significant (200+) and not consistent (linear). There is no way to know what the driven side is seeing and that's where the damage occurs. Also, protecting the exhaust valves is important. Temps at the manifold are generally more accurate. I do agree that the installation is more risky. I broke a tap in my manifold but fished the fragments out with a magnet through the hole. Always drill in a low spot so shavings fall back through the hole!

Re: 2014 diesel production

That is why if I were designing a production setup, the test mule would have a number of sensors at different places so a correlation could be drawn between a downstream (collective) reading and upstream readings at each exhaust port.

However that is something only a tuner would really need.

But for personal use I have enough experience that a downstream sensor is safer and will give me what I need and is just one thing I'd be watching. On my RV I can just watch the boost and revs and tell what the EGT is doing.

BTW to max power you want to keep the backpressure as low as possible & just a turbo itself quiets things down A Lot.

Re: 2014 diesel production

I guess one important thing is first to determine does the vehicle have a stock EGT sensor. Would the ECU typically need one? Anyone have a service manual to check ECU wiring diagrams?

Would be a lot easier to tap off that, unless no one knows what the signal voltage reference is to calibrate the gauge. In the end a stand-alone system may be easier.

EDIT: Found this:

http://thesensorconnection.com/egt-p...race-series-dp

You could hide it under the dash and have it alarm when reaching a set temp, pretty cool. I guess you would just need to drill and tap a hole just south of the turbo on the down-pipe? I wonder how much cooler the temp would be there versus right at the head/manifold connection.

EDIT: http://en.wikipedia.org/wiki/Exhaust...perature_gauge

According to that the temp drop from head outlet to post turbo could be as much as 200-300 degrees. Quite dramatic... Would definitely not drill pre-turbo, especially with the warranty issues you would run into. Can't hide a hole in your manifold!

Re: 2014 diesel production

Got an email today from my dealer. He told me that my unicorn is shipped to storage (which should be correct), and has a shipping date of 10/25. He never BS'ed me and kept radio silence as long as he didn't have something he could trust to tell me, so I really hope the date is going to hold.
